+ * HAL when a camera device's status changes:
+ *
+ *  1. A previously-disconnected camera device becomes connected. After

+ *      ICameraProviderCallback::TorchModeStatusChange() unless the flash unit
+ *      is unavailable to use by ICameraProvider::setTorchMode().
+ *
+ *  2. A previously-connected camera becomes disconnected. After

+ *      the camera service that the camera device is not present, the framework
+ *      must not call ICameraProvider::setTorchMode() for the disconnected camera
+ *      device until it is connected again. The camera provider HAL does not
+ *      need to invoke ICameraProviderCallback::TorchModeStatusChange()
+ *      separately to inform that the flash unit has become NOT_AVAILABLE.
+ *
+ *  3. openCameraDevice() or openCameraDeviceVersion() is called to open a
+ *      camera device. The camera provider HAL must invoke
+ *      ICameraProviderCallback::TorchModeStatusChange() for all flash units
+ *      that have entered NOT_AVAILABLE state and can not be turned on by
+ *      calling ICameraProvider::setTorchMode() due to this open() call.
+ *      openCameraDevice() must not trigger AVAILABLE_OFF before NOT_AVAILABLE
+ *      for all flash units that have become unavailable.
+ *
+ *  4. ICameraDevice.close() is called to close a camera device. The camera
+ *      provider HAL must call ICameraProviderCallback::torchModeStatusChange()
+ *      for all flash units that have now entered the AVAILABLE_OFF state and
+ *      can be turned on by calling ICameraProvider::setTorchMode() again because
+ *      of sufficient new camera resources being freed up by this close() call.
+ *
+ *  Note that the camera service calling ICameraProvider::setTorchMode()

+     * service.
+     *
+     * The camera service must be able to simultaneously open and use any

+     * the resource costs of these cameras is <= 100. For determining cost,

+     * the maximally resource-consuming framerate and stream size settings
+     * available in the configuration settings exposed for that device through
+     * the camera metadata.
+     *
+     * The camera service may still attempt to simultaneously open combinations

+     * fail. If this succeeds, combinations of configurations that are not
+     * supported due to resource constraints from having multiple open devices
+     * must fail during the configure calls. If the total resource cost is <=
+     * 100, open and configure must never fail for any stream configuration
+     * settings or other device capabilities that would normally succeed for a
+     * device when it is the only open camera device.
+     *
+     * This field may be used to determine whether background applications are
+     * allowed to use this camera device while other applications are using
+     * other camera devices. Note: multiple applications must never be allowed
+     * by the camera service to simultaneously open the same camera device.
+     *
+     * Example use cases:
+     *
+     * Ex. 1: Camera Device 0 = Back Camera
+     *        Camera Device 1 = Front Camera
+     *   - Using both camera devices causes a large framerate slowdown due to
+     *     limited ISP bandwidth.
+     *
+     *   Configuration:
+     *
+     *   Camera Device 0 - resourceCost = 51
+     *                     conflicting_devices = empty
+     *   Camera Device 1 - resourceCost = 51
+     *                     conflicting_devices = empty
+     *
+     *   Result:
+     *
+     *   Since the sum of the resource costs is > 100, if a higher-priority
+     *   application has either device open, no lower-priority applications must
+     *   be allowed by the camera service to open either device. If a
+     *   lower-priority application is using a device that a higher-priority
+     *   subsequently attempts to open, the lower-priority application must be
+     *   forced to disconnect the the device.
+     *
+     *   If the highest-priority application chooses, it may still attempt to
+     *   open both devices (since these devices are not listed as conflicting in
+     *   the conflicting_devices fields), but usage of these devices may fail in
+     *   the open or configure calls.
+     *
+     * Ex. 2: Camera Device 0 = Left Back Camera
+     *        Camera Device 1 = Right Back Camera
+     *        Camera Device 2 = Combined stereo camera using both right and left
+     *                          back camera sensors used by devices 0, and 1
+     *        Camera Device 3 = Front Camera
+     *   - Due to do hardware constraints, up to two cameras may be open at
+     *     once. The combined stereo camera may never be used at the same time
+     *     as either of the two back camera devices (device 0, 1), and typically
+     *     requires too much bandwidth to use at the same time as the front
+     *     camera (device 3).
+     *
+     *   Configuration:
+     *
+     *   Camera Device 0 - resourceCost = 50

+     *   Camera Device 3 - resourceCost = 50
+     *                     conflicting_devices = empty
+     *
+     *   Result:
+     *
+     *   Based on the conflicting_devices fields, the camera service guarantees
+     *   that the following sets of open devices must never be allowed: { 1, 2
+     *   }, { 0, 2 }.
+     *
+     *   Based on the resourceCost fields, if a high-priority foreground
+     *   application is using camera device 0, a background application would be
+     *   allowed to open camera device 1 or 3 (but would be forced to disconnect
+     *   it again if the foreground application opened another device).
+     *
+     *   The highest priority application may still attempt to simultaneously
+     *   open devices 0, 2, and 3, but the HAL may fail in open or configure
+     *   calls for this combination.

+     *        Camera Device 1 = Front Camera
+     *        Camera Device 2 = Low-power Front Camera that uses the same sensor

+     *                          resolutions that can be used in low-power mode
+     *  - Using both front cameras (device 1, 2) at the same time is impossible
+     *    due a shared physical sensor. Using the back and "high-power" front
+     *    camera (device 1) may be impossible for some stream configurations due
+     *    to hardware limitations, but the "low-power" front camera option may
+     *    always be used as it has special dedicated hardware.

+     *   Camera Device 0 - resourceCost = 100

+     * post-processed JPEG buffers in a later call, once it is available. Each
+     * call must include the frame number of the request it is returning
+     * metadata or buffers for.
+     *
+     * A component (buffer or metadata) of the complete result may only be

+     * output buffers or result metadata is not allowed.
+     *
+     * The order of returning metadata and buffers for a single result does not
+     * matter, but buffers for a given stream must be returned in FIFO order. So
+     * the buffer for request 5 for stream A must always be returned before the

+     * metadata; the metadata for request 5 must be returned before the metadata
+     * for request 6.

+     * However, different streams are independent of each other, so it is

+     * returned after the buffer for request 6 for stream B is. And it is
+     * acceptable that the result metadata for request 6 for stream B is
+     * returned before the buffer for request 5 for stream A is.
+     *
+     * The HAL retains ownership of result structure, which only needs to be
+     * valid to access during this call. The framework must copy whatever it
+     * needs before this call returns.
+     *
+     * The output buffers do not need to be filled yet; the framework must wait
+     * on the stream buffer release sync fence before reading the buffer
+     * data. Therefore, this method should be called by the HAL as soon as
+     * possible, even if some or all of the output buffers are still in
+     * being filled. The HAL must include valid release sync fences into each
+     * output_buffers stream buffer entry, or -1 if that stream buffer is
+     * already filled.
+     *
+     * If the result buffer cannot be constructed for a request, the HAL must
+     * return an empty metadata buffer, but still provide the output buffers and
+     * their sync fences. In addition, notify() must be called with an
+     * ERROR_RESULT message.
+     *
+     * If an output buffer cannot be filled, its status field must be set to
+     * STATUS_ERROR. In addition, notify() must be called with a ERROR_BUFFER
+     * message.
+     *
+     * If the entire capture has failed, then this method still needs to be
+     * called to return the output buffers to the framework. All the buffer
+     * statuses must be STATUS_ERROR, and the result metadata must be an
+     * empty buffer. In addition, notify() must be called with a ERROR_REQUEST
+     * message. In this case, individual ERROR_RESULT/ERROR_BUFFER messages
+     * must not be sent.
+     *
+     * Performance requirements:
+     *
+     * This is a non-blocking call. The framework must return this call in 5ms.
+     *
+     * The pipeline latency (see S7 for definition) should be less than or equal to

+     *
+     * The streamList must contain at least one output-capable stream, and may

+     * If the stream is new, the maxBuffer field of the stream structure must be
+     * set to 0. The usage must be set to the consumer usage flags. The HAL
+     * device must set these fields in the configureStreams() return values.
+     * These fields are then used by the framework and the platform gralloc
+     * module to allocate the gralloc buffers for each stream.

+     * processed. That is, all results have been returned to the framework, and
+     * all in-flight input and output buffers have been returned and their
+     * release sync fences have been signaled by the HAL. The framework must not
+     * submit new requests for capture while the configureStreams() call is
+     * underway.
+     *
+     * Postconditions:
+     *
+     * The HAL device must configure itself to provide maximum possible output
+     * frame rate given the sizes and formats of the output streams, as
+     * documented in the camera device's static metadata.
+     *
+     * Performance requirements:
+     *
+     * This call is expected to be heavyweight and possibly take several hundred
+     * milliseconds to complete, since it may require resetting and
+     * reconfiguring the image sensor and the camera processing pipeline.
+     * Nevertheless, the HAL device should attempt to minimize the
+     * reconfiguration delay to minimize the user-visible pauses during
+     * application operational mode changes (such as switching from still
+     * capture to video recording).
+     *
+     * The HAL should return from this call in 500ms, and must return from this
+     * call in 1000ms.

+     * @return Status Status code for the operation, one of:
+     *     OK:
+     *          On successful stream configuration.
+     *     INTERNAL_ERROR:
+     *         If there has been a fatal error and the device is no longer
+     *         operational. Only close() can be called successfully by the
+     *         framework after this error is returned.
+     *     ILLEGAL_ARGUMENT:
+     *         If the requested stream configuration is invalid. Some examples
+     *         of invalid stream configurations include:
+     *           - Including more than 1 INPUT stream
+     *           - Not including any OUTPUT streams
+     *           - Including streams with unsupported formats, or an unsupported
+     *             size for that format.
+     *           - Including too many output streams of a certain format.
+     *           - Unsupported rotation configuration
+     *           - Stream sizes/formats don't satisfy the
+     *             camera3_stream_configuration_t->operation_mode requirements
+     *             for non-NORMAL mode, or the requested operation_mode is not
+     *             supported by the HAL.
+     *         The camera service cannot filter out all possible illegal stream
+     *         configurations, since some devices may support more simultaneous
+     *         streams or larger stream resolutions than the minimum required
+     *         for a given camera device hardware level. The HAL must return an
+     *         ILLEGAL_ARGUMENT for any unsupported stream set, and then be
+     *         ready to accept a future valid stream configuration in a later
+     *         configureStreams call.

+     * its associated buffers are available. In a normal preview scenario, this
+     * means the function is generally called again by the framework almost
+     * instantly.
+     *
+     * The actual request processing is asynchronous, with the results of

+     * call. This call requires the result metadata to be available, but output
+     * buffers may simply provide sync fences to wait on. Multiple requests are

+     *
+     * The framework retains ownership of the request structure. It is only

+     * no frame rate degradation or frame jitter introduced.
+     *
+     * This call must return fast enough to ensure that the requested frame
+     * rate can be sustained, especially for streaming cases (post-processing
+     * quality settings set to FAST). The HAL should return this call in 1

+     * Flush all currently in-process captures and all buffers in the pipeline
+     * on the given device. Generally, this method is used to dump all state as
+     * quickly as possible in order to prepare for a configure_streams() call.
+     *
+     * No buffers are required to be successfully returned, so every buffer
+     * held at the time of flush() (whether successfully filled or not) may be
+     * returned with CAMERA3_BUFFER_STATUS_ERROR. Note the HAL is still allowed
+     * to return valid (CAMERA3_BUFFER_STATUS_OK) buffers during this call,
+     * provided they are successfully filled.
+     *
+     * All requests currently in the HAL are expected to be returned as soon as
+     * possible. Not-in-process requests must return errors immediately. Any
+     * interruptible hardware blocks must be stopped, and any uninterruptible
+     * blocks must be waited on.
+     *
+     * flush() may be called concurrently to processCaptureRequest(), with the
+     * expectation that processCaptureRequest returns quickly and the
+     * request submitted in that processCaptureRequest call is treated like
+     * all other in-flight requests. Due to concurrency issues, it is possible
+     * that from the HAL's point of view, a processCaptureRequest() call may
+     * be started after flush has been invoked but has not returned yet. If such
+     * a call happens before flush() returns, the HAL must treat the new
+     * capture request like other in-flight pending requests (see #4 below).
+     *
+     * More specifically, the HAL must follow below requirements for various
+     * cases:
+     *
+     * 1. For captures that are too late for the HAL to cancel/stop, and must be
+     *    completed normally by the HAL; i.e. the HAL can send shutter/notify
+     *    and processCaptureResult and buffers as normal.
+     *
+     * 2. For pending requests that have not done any processing, the HAL must
+     *    call notify CAMERA3_MSG_ERROR_REQUEST, and return all the output
+     *    buffers with processCaptureResult in the error state
+     *    (CAMERA3_BUFFER_STATUS_ERROR). The HAL must not place the release
+     *    fence into an error state, instead, the release fences must be set to
+     *    the acquire fences passed by the framework, or -1 if they have been
+     *    waited on by the HAL already. This is also the path to follow for any
+     *    captures for which the HAL already called notify() with
+     *    CAMERA3_MSG_SHUTTER but won't be producing any metadata/valid buffers
+     *    for. After CAMERA3_MSG_ERROR_REQUEST, for a given frame, only
+     *    processCaptureResults with buffers in CAMERA3_BUFFER_STATUS_ERROR
+     *    are allowed. No further notifys or processCaptureResult with
+     *    non-empty metadata is allowed.
+     *
+     * 3. For partially completed pending requests that do not have all the
+     *    output buffers or perhaps missing metadata, the HAL must follow
+     *    below:
+     *
+     *    3.1. Call notify with CAMERA3_MSG_ERROR_RESULT if some of the expected
+     *         result metadata (i.e. one or more partial metadata) won't be
+     *         available for the capture.
+     *
+     *    3.2. Call notify with CAMERA3_MSG_ERROR_BUFFER for every buffer that
+     *         won't be produced for the capture.
+     *
+     *    3.3. Call notify with CAMERA3_MSG_SHUTTER with the capture timestamp
+     *         before any buffers/metadata are returned with
+     *         processCaptureResult.
+     *
+     *    3.4. For captures that will produce some results, the HAL must not
+     *         call CAMERA3_MSG_ERROR_REQUEST, since that indicates complete
+     *         failure.
+     *
+     *    3.5. Valid buffers/metadata must be passed to the framework as
+     *         normal.
+     *
+     *    3.6. Failed buffers must be returned to the framework as described
+     *         for case 2. But failed buffers do not have to follow the strict
+     *         ordering valid buffers do, and may be out-of-order with respect
+     *         to valid buffers. For example, if buffers A, B, C, D, E are sent,
+     *         D and E are failed, then A, E, B, D, C is an acceptable return
+     *         order.
+     *
+     *    3.7. For fully-missing metadata, calling CAMERA3_MSG_ERROR_RESULT is
+     *         sufficient, no need to call processCaptureResult with empty
+     *         metadata or equivalent.
+     *
+     * 4. If a flush() is invoked while a processCaptureRequest() invocation
+     *    is active, that process call must return as soon as possible. In
+     *    addition, if a processCaptureRequest() call is made after flush()
+     *    has been invoked but before flush() has returned, the capture request
+     *    provided by the late processCaptureRequest call must be treated
+     *    like a pending request in case #2 above.
+     *
+     * flush() must only return when there are no more outstanding buffers or
+     * requests left in the HAL. The framework may call configure_streams (as
+     * the HAL state is now quiesced) or may issue new requests.
+     *
+     * Note that it's sufficient to only support fully-succeeded and
+     * fully-failed result cases. However, it is highly desirable to support
+     * the partial failure cases as well, as it could help improve the flush
+     * call overall performance.
+     *
+     * Performance requirements:
+     *
+     * The HAL should return from this call in 100ms, and must return from this
+     * call in 1000ms. And this call must not be blocked longer than pipeline
+     * latency (see S7 for definition).

+     *   1. The HAL must support up to 2 streams with sizes reported by
+     *      android.control.availableHighSpeedVideoConfigurations.
+     *   2. In this mode, the HAL is expected to output up to 120fps or
+     *      higher. This mode must support the targeted FPS range and size
+     *      configurations reported by
+     *      android.control.availableHighSpeedVideoConfigurations.
+     *   3. The HAL must support IMPLEMENTATION_DEFINED output
+     *      stream format.
+     *   4. To achieve efficient high speed streaming, the HAL may have to
+     *      aggregate multiple frames together and send to camera device for
+     *      processing where the request controls are same for all the frames in
+     *      this batch (batch mode). The HAL must support max batch size and the
+     *      max batch size requirements defined by
+     *      android.control.availableHighSpeedVideoConfigurations.
+     *   5. In this mode, the HAL must override aeMode, awbMode, and afMode to
+     *      ON, ON, and CONTINUOUS_VIDEO, respectively. All post-processing
+     *      block mode controls must be overridden to be FAST. Therefore, no
+     *      manual control of capture and post-processing parameters is
+     *      possible. All other controls operate the same as when

+## Camera Device HAL ##
+---
+
+## Overview: ##
+
+The camera.device HAL interface is used by the Android camera service to operate
+individual camera devices. Instances of camera.device HAL interface can be obtained
+via one of the ICameraProvider::getCameraDeviceInterface_V<N>_x() methods, where N
+is the major version of the camera device interface.
+
+Obtaining the device interface does not turn on the respective camera device;
+each camera device interface has an actual open() method to begin an active
+camera session. Without invoking open(), the interface can be used for querying
+camera static information.
+
+More complete information about the Android camera HAL and subsystem can be found at
+[source.android.com](http://source.android.com/devices/camera/index.html).
+
+## Version history: ##
+
+### ICameraDevice.hal@1.0:
+
+HIDL version of the legacy camera device HAL. Intended as a shim for devices
+needing to use the deprecated pre-HIDL camera device HAL v1.0.
+
+May be used in HIDL passthrough mode for devices upgrading to the Android O
+release; must be used in binderized mode for devices launching in the O release.
+
+It is strongly recommended to not use this interface for new devices, as new
+devices may not use this interface starting with the Android P release, and all
+support for ICameraDevice@1.0 will be removed with the Android R release.
+
+This HAL interface version only allows support at the LEGACY level for the
+android.hardware.camera2 API.
+
+Subsidiary HALs:
+
+#### ICameraDevice1PreviewCallback.hal@1.0:
+
+Callback interface for obtaining, filling, and returning graphics buffers for
+preview operation with the ICameraDevice@1.0 inteface.
+
+#### ICameraDevice1Callback.hal@1.0:
+
+Callback interface for sending events and data buffers from the HAL to the
+camera service.
+
+### ICameraDevice.hal@3.2:
+
+HIDL version of the baseline camera device HAL, required for LIMITED or FULL
+operation through the android.hardware.camera2 API.
+
+The main HAL contains methods for static queries about the device, similar to
+the HALv3-specific sections of the legacy camera module HAL. Simply obtaining an
+instance of the camera device interface does not turn on the camera device.
+
+May be used in passthrough mode for devices upgrading to the Android O release;
+must be used in binderized mode for all new devices launching with Android O or
+later.
+
+The open() method actually opens the camera device for use, returning a Session
+interface for operating the active camera. It takes a Callback interface as an
+argument.
+
+Subsidiary HALs:
+
+#### ICameraDevice3Session.hal@3.2:
+
+Closely matches the features and operation of the pre-HIDL camera device HAL
+v3.2, containing methods for configuring an active camera device and submitting
+capture requests to it.
+
+#### ICameraDevice3Callback.hal@3.2:
+
+Callback interface for sending completed captures and other asynchronous events
+from tehe HAL to the client.

+control is overridden by the AWB routine.<wbr/> When AWB is disabled,<wbr/> the
+application controls how the color mapping is performed.<wbr/></p>
+<p>We define the expected processing pipeline below.<wbr/> For consistency
+across devices,<wbr/> this is always the case with TRANSFORM_<wbr/>MATRIX.<wbr/></p>
+<p>When either FULL or HIGH_<wbr/>QUALITY is used,<wbr/> the camera device may
+do additional processing but <a href="#controls_android.colorCorrection.gains">android.<wbr/>color<wbr/>Correction.<wbr/>gains</a> and
+<a href="#controls_android.colorCorrection.transform">android.<wbr/>color<wbr/>Correction.<wbr/>transform</a> will still be provided by the
+camera device (in the results) and be roughly correct.<wbr/></p>
+<p>Switching to TRANSFORM_<wbr/>MATRIX and using the data provided from
+FAST or HIGH_<wbr/>QUALITY will yield a picture with the same white point
+as what was produced by the camera device in the earlier frame.<wbr/></p>
+<p>The expected processing pipeline is as follows:</p>
+<p><img alt="White balance processing pipeline" src="images/camera2/metadata/android.colorCorrection.mode/processing_pipeline.png"/></p>
+<p>The white balance is encoded by two values,<wbr/> a 4-channel white-balance
+gain vector (applied in the Bayer domain),<wbr/> and a 3x3 color transform
+matrix (applied after demosaic).<wbr/></p>
+<p>The 4-channel white-balance gains are defined as:</p>
+<pre><code><a href="#controls_android.colorCorrection.gains">android.<wbr/>color<wbr/>Correction.<wbr/>gains</a> = [ R G_<wbr/>even G_<wbr/>odd B ]
+</code></pre>
+<p>where <code>G_<wbr/>even</code> is the gain for green pixels on even rows of the
+output,<wbr/> and <code>G_<wbr/>odd</code> is the gain for green pixels on the odd rows.<wbr/>
+These may be identical for a given camera device implementation; if
+the camera device does not support a separate gain for even/<wbr/>odd green
+channels,<wbr/> it will use the <code>G_<wbr/>even</code> value,<wbr/> and write <code>G_<wbr/>odd</code> equal to
+<code>G_<wbr/>even</code> in the output result metadata.<wbr/></p>
+<p>The matrices for color transforms are defined as a 9-entry vector:</p>
+<pre><code><a href="#controls_android.colorCorrection.transform">android.<wbr/>color<wbr/>Correction.<wbr/>transform</a> = [ I0 I1 I2 I3 I4 I5 I6 I7 I8 ]
+</code></pre>
+<p>which define a transform from input sensor colors,<wbr/> <code>P_<wbr/>in = [ r g b ]</code>,<wbr/>
+to output linear sRGB,<wbr/> <code>P_<wbr/>out = [ r' g' b' ]</code>,<wbr/></p>
+<p>with colors as follows:</p>
+<pre><code>r' = I0r + I1g + I2b
+g' = I3r + I4g + I5b

+<li>Starting in auto-AE mode:</li>

+              <p>This entry is normally set to IDLE,<wbr/> or is not
+included at all in the request settings.<wbr/> When included and
+set to START,<wbr/> the camera device will trigger the auto-exposure (AE)
+precapture metering sequence.<wbr/></p>
+<p>When set to CANCEL,<wbr/> the camera device will cancel any active
+precapture metering trigger,<wbr/> and return to its initial AE state.<wbr/>
+If a precapture metering sequence is already completed,<wbr/> and the camera
+device has implicitly locked the AE for subsequent still capture,<wbr/> the
+CANCEL trigger will unlock the AE and return to its initial AE state.<wbr/></p>
+<p>The precapture sequence should be triggered before starting a
+high-quality still capture for final metering decisions to
+be made,<wbr/> and for firing pre-capture flash pulses to estimate
+scene brightness and required final capture flash power,<wbr/> when
+the flash is enabled.<wbr/></p>
+<p>Normally,<wbr/> this entry should be set to START for only a
+single request,<wbr/> and the application should wait until the
+sequence completes before starting a new one.<wbr/></p>
+<p>When a precapture metering sequence is finished,<wbr/> the camera device
+may lock the auto-exposure routine internally to be able to accurately expose the
+subsequent still capture image (<code><a href="#controls_android.control.captureIntent">android.<wbr/>control.<wbr/>capture<wbr/>Intent</a> == STILL_<wbr/>CAPTURE</code>).<wbr/>
+For this case,<wbr/> the AE may not resume normal scan if no subsequent still capture is
+submitted.<wbr/> To ensure that the AE routine restarts normal scan,<wbr/> the application should
+submit a request with <code><a href="#controls_android.control.aeLock">android.<wbr/>control.<wbr/>ae<wbr/>Lock</a> == true</code>,<wbr/> followed by a request
+with <code><a href="#controls_android.control.aeLock">android.<wbr/>control.<wbr/>ae<wbr/>Lock</a> == false</code>,<wbr/> if the application decides not to submit a
+still capture request after the precapture sequence completes.<wbr/> Alternatively,<wbr/> for
+API level 23 or newer devices,<wbr/> the CANCEL can be used to unlock the camera device
+internally locked AE if the application doesn't submit a still capture request after
+the AE precapture trigger.<wbr/> Note that,<wbr/> the CANCEL was added in API level 23,<wbr/> and must not
+be used in devices that have earlier API levels.<wbr/></p>
+<p>The exact effect of auto-exposure (AE) precapture trigger
+depends on the current AE mode and state; see
+<a href="#dynamic_android.control.aeState">android.<wbr/>control.<wbr/>ae<wbr/>State</a> for AE precapture state transition
+details.<wbr/></p>
+<p>On LEGACY-level devices,<wbr/> the precapture trigger is not supported;
+capturing a high-resolution JPEG image will automatically trigger a
+precapture sequence before the high-resolution capture,<wbr/> including
+potentially firing a pre-capture flash.<wbr/></p>
+<p>Using the precapture trigger and the auto-focus trigger <a href="#controls_android.control.afTrigger">android.<wbr/>control.<wbr/>af<wbr/>Trigger</a>
+simultaneously is allowed.<wbr/> However,<wbr/> since these triggers often require cooperation between
+the auto-focus and auto-exposure routines (for example,<wbr/> the may need to be enabled for a
+focus sweep),<wbr/> the camera device may delay acting on a later trigger until the previous
+trigger has been fully handled.<wbr/> This may lead to longer intervals between the trigger and
+changes to <a href="#dynamic_android.control.aeState">android.<wbr/>control.<wbr/>ae<wbr/>State</a> indicating the start of the precapture sequence,<wbr/> for
+example.<wbr/></p>
+<p>If both the precapture and the auto-focus trigger are activated on the same request,<wbr/> then
+the camera device will complete them in the optimal order for that device.<wbr/></p>

+              <p>When afMode is AUTO or MACRO,<wbr/> the lens must not move until an AF trigger is sent in a
+request (<a href="#controls_android.control.afTrigger">android.<wbr/>control.<wbr/>af<wbr/>Trigger</a> <code>==</code> START).<wbr/> After an AF trigger,<wbr/> the afState will end
+up with either FOCUSED_<wbr/>LOCKED or NOT_<wbr/>FOCUSED_<wbr/>LOCKED state (see
+<a href="#dynamic_android.control.afState">android.<wbr/>control.<wbr/>af<wbr/>State</a> for detailed state transitions),<wbr/> which indicates that the lens is
+locked and will not move.<wbr/> If camera movement (e.<wbr/>g.<wbr/> tilting camera) causes the lens to move
+after the lens is locked,<wbr/> the HAL must compensate this movement appropriately such that
+the same focal plane remains in focus.<wbr/></p>
+<p>When afMode is one of the continuous auto focus modes,<wbr/> the HAL is free to start a AF
+scan whenever it's not locked.<wbr/> When the lens is locked after an AF trigger
+(see <a href="#dynamic_android.control.afState">android.<wbr/>control.<wbr/>af<wbr/>State</a> for detailed state transitions),<wbr/> the HAL should maintain the
+same lock behavior as above.<wbr/></p>
+<p>When afMode is OFF,<wbr/> the application controls focus manually.<wbr/> The accuracy of the
+focus distance control depends on the <a href="#static_android.lens.info.focusDistanceCalibration">android.<wbr/>lens.<wbr/>info.<wbr/>focus<wbr/>Distance<wbr/>Calibration</a>.<wbr/>
+However,<wbr/> the lens must not move regardless of the camera movement for any focus distance

+<p>To put this in concrete terms,<wbr/> if the camera has lens elements which may move based on
+camera orientation or motion (e.<wbr/>g.<wbr/> due to gravity),<wbr/> then the HAL must drive the lens to
+remain in a fixed position invariant to the camera's orientation or motion,<wbr/> for example,<wbr/>
+by using accelerometer measurements in the lens control logic.<wbr/> This is a typical issue
+that will arise on camera modules with open-loop VCMs.<wbr/></p>

+<p>In this scene mode,<wbr/> the camera device captures images

+picture of a object in front of a bright window,<wbr/> both
+the object and the scene through the window may be
+visible when using HDR mode,<wbr/> while in normal AUTO mode,<wbr/>
+one or the other may be poorly exposed.<wbr/> As a tradeoff,<wbr/>
+HDR mode generally takes much longer to capture a single
+image,<wbr/> has no user control,<wbr/> and may have other artifacts
+depending on the HDR method used.<wbr/></p>
+<p>Therefore,<wbr/> HDR captures operate at a much slower rate
+than regular captures.<wbr/></p>
+<p>In this mode,<wbr/> on LIMITED or FULL devices,<wbr/> when a request
+is made with a <a href="#controls_android.control.captureIntent">android.<wbr/>control.<wbr/>capture<wbr/>Intent</a> of
+STILL_<wbr/>CAPTURE,<wbr/> the camera device will capture an image
+using a high dynamic range capture technique.<wbr/>  On LEGACY
+devices,<wbr/> captures that target a JPEG-format output will
+be captured with HDR,<wbr/> and the capture intent is not
+relevant.<wbr/></p>
+<p>The HDR capture may involve the device capturing a burst
+of images internally and combining them into one,<wbr/> or it
+may involve the device using specialized high dynamic
+range capture hardware.<wbr/> In all cases,<wbr/> a single image is
+produced in response to a capture request submitted
+while in HDR mode.<wbr/></p>
+<p>Since substantial post-processing is generally needed to
+produce an HDR image,<wbr/> only YUV,<wbr/> PRIVATE,<wbr/> and JPEG
+outputs are supported for LIMITED/<wbr/>FULL device HDR
+captures,<wbr/> and only JPEG outputs are supported for LEGACY
+HDR captures.<wbr/> Using a RAW output for HDR capture is not
+supported.<wbr/></p>
+<p>Some devices may also support always-on HDR,<wbr/> which
+applies HDR processing at full frame rate.<wbr/>  For these
+devices,<wbr/> intents other than STILL_<wbr/>CAPTURE will also
+produce an HDR output with no frame rate impact compared
+to normal operation,<wbr/> though the quality may be lower
+than for STILL_<wbr/>CAPTURE intents.<wbr/></p>
+<p>If SCENE_<wbr/>MODE_<wbr/>HDR is used with unsupported output types

+<p>For the high speed video use case,<wbr/> the application must

+configure output streams.<wbr/> Once the size is selected,<wbr/> application can filter this metadata
+by selected size and get the supported fps ranges,<wbr/> and use these fps ranges to setup the
+recording requests.<wbr/> Note that for the use case of multiple output streams,<wbr/> application
+must select one unique size from this metadata to use (e.<wbr/>g.,<wbr/> preview and recording streams
+must have the same size).<wbr/> Otherwise,<wbr/> the high speed capture session creation will fail.<wbr/></p>
+<p>The min and max fps will be multiple times of 30fps.<wbr/></p>
+<p>High speed video streaming extends significant performance pressue to camera hardware,<wbr/>
+to achieve efficient high speed streaming,<wbr/> the camera device may have to aggregate
+multiple frames together and send to camera device for processing where the request
+controls are same for all the frames in this batch.<wbr/> Max batch size indicates
+the max possible number of frames the camera device will group together for this high
+speed stream configuration.<wbr/> This max batch size will be used to generate a high speed
+recording request list by
+<a href="https://developer.android.com/reference/android/hardware/camera2/CameraConstrainedHighSpeedCaptureSession.html#createHighSpeedRequestList">CameraConstrainedHighSpeedCaptureSession#createHighSpeedRequestList</a>.<wbr/>
+The max batch size for each configuration will satisfy below conditions:</p>
+<ul>
+<li>Each max batch size will be a divisor of its corresponding fps_<wbr/>max /<wbr/> 30.<wbr/> For example,<wbr/>
+if max_<wbr/>fps is 300,<wbr/> max batch size will only be 1,<wbr/> 2,<wbr/> 5,<wbr/> or 10.<wbr/></li>
+<li>The camera device may choose smaller internal batch size for each configuration,<wbr/> but
+the actual batch size will be a divisor of max batch size.<wbr/> For example,<wbr/> if the max batch
+size is 8,<wbr/> the actual batch size used by camera device will only be 1,<wbr/> 2,<wbr/> 4,<wbr/> or 8.<wbr/></li>
+<li>The max batch size in each configuration entry must be no larger than 32.<wbr/></li>
+</ul>
+<p>The camera device doesn't have to support batch mode to achieve high speed video recording,<wbr/>
+in such case,<wbr/> batch_<wbr/>size_<wbr/>max will be reported as 1 in each configuration entry.<wbr/></p>
+<p>This fps ranges in this configuration list can only be used to create requests

+Note that for all high speed video configurations,<wbr/> HAL must be able to support a minimum

+<p>The HAL may support multiple sensor modes for high speed outputs,<wbr/> for example,<wbr/> 120fps
+sensor mode and 120fps recording,<wbr/> 240fps sensor mode for 240fps recording.<wbr/> The application
+usually starts preview first,<wbr/> then starts recording.<wbr/> To avoid sensor mode switch caused
+stutter when starting recording as much as possible,<wbr/> the application may want to ensure
+the same sensor mode is used for preview and recording.<wbr/> Therefore,<wbr/> The HAL must advertise
+the variable fps range [30,<wbr/> fps_<wbr/>max] for each fixed fps range in this configuration list.<wbr/>
+For example,<wbr/> if the HAL advertises [120,<wbr/> 120] and [240,<wbr/> 240],<wbr/> the HAL must also advertise
+[30,<wbr/> 120] and [30,<wbr/> 240] for each configuration.<wbr/> In doing so,<wbr/> if the application intends to
+do 120fps recording,<wbr/> it can select [30,<wbr/> 120] to start preview,<wbr/> and [120,<wbr/> 120] to start
+recording.<wbr/> For these variable fps ranges,<wbr/> it's up to the HAL to decide the actual fps
+values that are suitable for smooth preview streaming.<wbr/> If the HAL sees different max_<wbr/>fps
+values that fall into different sensor modes in a sequence of requests,<wbr/> the HAL must
+switch the sensor mode as quick as possible to minimize the mode switch caused stutter.<wbr/></p>

+<p>Since the camera device has a pipeline of in-flight requests,<wbr/> the settings that
+get locked do not necessarily correspond to the settings that were present in the
+latest capture result received from the camera device,<wbr/> since additional captures
+and AE updates may have occurred even before the result was sent out.<wbr/> If an
+application is switching between automatic and manual control and wishes to eliminate

+<ol>
+<li>Starting in auto-AE mode:</li>
+<li>Lock AE</li>
+<li>Wait for the first result to be output that has the AE locked</li>
+<li>Copy exposure settings from that result into a request,<wbr/> set the request to manual AE</li>

+              <p>This entry is normally set to IDLE,<wbr/> or is not
+included at all in the request settings.<wbr/> When included and
+set to START,<wbr/> the camera device will trigger the auto-exposure (AE)
+precapture metering sequence.<wbr/></p>
+<p>When set to CANCEL,<wbr/> the camera device will cancel any active
+precapture metering trigger,<wbr/> and return to its initial AE state.<wbr/>
+If a precapture metering sequence is already completed,<wbr/> and the camera
+device has implicitly locked the AE for subsequent still capture,<wbr/> the
+CANCEL trigger will unlock the AE and return to its initial AE state.<wbr/></p>
+<p>The precapture sequence should be triggered before starting a
+high-quality still capture for final metering decisions to
+be made,<wbr/> and for firing pre-capture flash pulses to estimate
+scene brightness and required final capture flash power,<wbr/> when
+the flash is enabled.<wbr/></p>
+<p>Normally,<wbr/> this entry should be set to START for only a
+single request,<wbr/> and the application should wait until the
+sequence completes before starting a new one.<wbr/></p>
+<p>When a precapture metering sequence is finished,<wbr/> the camera device
+may lock the auto-exposure routine internally to be able to accurately expose the
+subsequent still capture image (<code><a href="#controls_android.control.captureIntent">android.<wbr/>control.<wbr/>capture<wbr/>Intent</a> == STILL_<wbr/>CAPTURE</code>).<wbr/>
+For this case,<wbr/> the AE may not resume normal scan if no subsequent still capture is
+submitted.<wbr/> To ensure that the AE routine restarts normal scan,<wbr/> the application should
+submit a request with <code><a href="#controls_android.control.aeLock">android.<wbr/>control.<wbr/>ae<wbr/>Lock</a> == true</code>,<wbr/> followed by a request
+with <code><a href="#controls_android.control.aeLock">android.<wbr/>control.<wbr/>ae<wbr/>Lock</a> == false</code>,<wbr/> if the application decides not to submit a
+still capture request after the precapture sequence completes.<wbr/> Alternatively,<wbr/> for
+API level 23 or newer devices,<wbr/> the CANCEL can be used to unlock the camera device
+internally locked AE if the application doesn't submit a still capture request after
+the AE precapture trigger.<wbr/> Note that,<wbr/> the CANCEL was added in API level 23,<wbr/> and must not
+be used in devices that have earlier API levels.<wbr/></p>
+<p>The exact effect of auto-exposure (AE) precapture trigger
+depends on the current AE mode and state; see
+<a href="#dynamic_android.control.aeState">android.<wbr/>control.<wbr/>ae<wbr/>State</a> for AE precapture state transition
+details.<wbr/></p>
+<p>On LEGACY-level devices,<wbr/> the precapture trigger is not supported;
+capturing a high-resolution JPEG image will automatically trigger a
+precapture sequence before the high-resolution capture,<wbr/> including
+potentially firing a pre-capture flash.<wbr/></p>
+<p>Using the precapture trigger and the auto-focus trigger <a href="#controls_android.control.afTrigger">android.<wbr/>control.<wbr/>af<wbr/>Trigger</a>
+simultaneously is allowed.<wbr/> However,<wbr/> since these triggers often require cooperation between
+the auto-focus and auto-exposure routines (for example,<wbr/> the may need to be enabled for a
+focus sweep),<wbr/> the camera device may delay acting on a later trigger until the previous
+trigger has been fully handled.<wbr/> This may lead to longer intervals between the trigger and
+changes to <a href="#dynamic_android.control.aeState">android.<wbr/>control.<wbr/>ae<wbr/>State</a> indicating the start of the precapture sequence,<wbr/> for
+example.<wbr/></p>
+<p>If both the precapture and the auto-focus trigger are activated on the same request,<wbr/> then
+the camera device will complete them in the optimal order for that device.<wbr/></p>

+<p>In this scene mode,<wbr/> the camera device captures images
+that keep a larger range of scene illumination levels
+visible in the final image.<wbr/> For example,<wbr/> when taking a
+picture of a object in front of a bright window,<wbr/> both
+the object and the scene through the window may be
+visible when using HDR mode,<wbr/> while in normal AUTO mode,<wbr/>
+one or the other may be poorly exposed.<wbr/> As a tradeoff,<wbr/>
+HDR mode generally takes much longer to capture a single
+image,<wbr/> has no user control,<wbr/> and may have other artifacts
+depending on the HDR method used.<wbr/></p>
+<p>Therefore,<wbr/> HDR captures operate at a much slower rate
+than regular captures.<wbr/></p>
+<p>In this mode,<wbr/> on LIMITED or FULL devices,<wbr/> when a request
+is made with a <a href="#controls_android.control.captureIntent">android.<wbr/>control.<wbr/>capture<wbr/>Intent</a> of
+STILL_<wbr/>CAPTURE,<wbr/> the camera device will capture an image
+using a high dynamic range capture technique.<wbr/>  On LEGACY
+devices,<wbr/> captures that target a JPEG-format output will
+be captured with HDR,<wbr/> and the capture intent is not
+relevant.<wbr/></p>
+<p>The HDR capture may involve the device capturing a burst
+of images internally and combining them into one,<wbr/> or it
+may involve the device using specialized high dynamic
+range capture hardware.<wbr/> In all cases,<wbr/> a single image is
+produced in response to a capture request submitted
+while in HDR mode.<wbr/></p>
+<p>Since substantial post-processing is generally needed to
+produce an HDR image,<wbr/> only YUV,<wbr/> PRIVATE,<wbr/> and JPEG
+outputs are supported for LIMITED/<wbr/>FULL device HDR
+captures,<wbr/> and only JPEG outputs are supported for LEGACY
+HDR captures.<wbr/> Using a RAW output for HDR capture is not
+supported.<wbr/></p>
+<p>Some devices may also support always-on HDR,<wbr/> which
+applies HDR processing at full frame rate.<wbr/>  For these
+devices,<wbr/> intents other than STILL_<wbr/>CAPTURE will also
+produce an HDR output with no frame rate impact compared
+to normal operation,<wbr/> though the quality may be lower
+than for STILL_<wbr/>CAPTURE intents.<wbr/></p>
+<p>If SCENE_<wbr/>MODE_<wbr/>HDR is used with unsupported output types
+or capture intents,<wbr/> the images captured will be as if
+the SCENE_<wbr/>MODE was not enabled at all.<wbr/></p></span>

+<p>The camera device may be tuned to expose the images in a reduced

+FPS ranges in <a href="#static_android.control.aeAvailableTargetFpsRanges">android.<wbr/>control.<wbr/>ae<wbr/>Available<wbr/>Target<wbr/>Fps<wbr/>Ranges</a>.<wbr/> For this case,<wbr/> all normal

+the high speed fps ranges,<wbr/> the same as all other fps ranges.<wbr/> This capability describes
+the capability of a specialized operating mode with many limitations (see below),<wbr/> which
+is only targeted at high speed video recording.<wbr/></p>
+<p>The supported high speed video sizes and fps ranges are specified in
+<a href="https://developer.android.com/reference/android/hardware/camera2/params/StreamConfigurationMap.html#getHighSpeedVideoFpsRanges">StreamConfigurationMap#getHighSpeedVideoFpsRanges</a>.<wbr/>
+To get desired output frame rates,<wbr/> the application is only allowed to select video size
+and FPS range combinations provided by
+<a href="https://developer.android.com/reference/android/hardware/camera2/params/StreamConfigurationMap.html#getHighSpeedVideoSizes">StreamConfigurationMap#getHighSpeedVideoSizes</a>.<wbr/>
+The fps range can be controlled via <a href="#controls_android.control.aeTargetFpsRange">android.<wbr/>control.<wbr/>ae<wbr/>Target<wbr/>Fps<wbr/>Range</a>.<wbr/></p>
+<p>In this capability,<wbr/> the camera device will override aeMode,<wbr/> awbMode,<wbr/> and afMode to
+ON,<wbr/> AUTO,<wbr/> and CONTINUOUS_<wbr/>VIDEO,<wbr/> respectively.<wbr/> All post-processing block mode
+controls will be overridden to be FAST.<wbr/> Therefore,<wbr/> no manual control of capture
+and post-processing parameters is possible.<wbr/> All other controls operate the
+same as when <a href="#controls_android.control.mode">android.<wbr/>control.<wbr/>mode</a> == AUTO.<wbr/> This means that all other

+<ul>
+<li><a href="#controls_android.flash.mode">android.<wbr/>flash.<wbr/>mode</a> (TORCH mode only,<wbr/> automatic flash for still capture will not

+</ul>
+<p>For high speed recording use case,<wbr/> the actual maximum supported frame rate may
+be lower than what camera can output,<wbr/> depending on the destination Surfaces for
+the image data.<wbr/> For example,<wbr/> if the destination surface is from video encoder,<wbr/>
+the application need check if the video encoder is capable of supporting the
+high frame rate for a given video size,<wbr/> or it will end up with lower recording
+frame rate.<wbr/> If the destination surface is from preview window,<wbr/> the actual preview frame
+rate will be bounded by the screen refresh rate.<wbr/></p>
+<p>The camera device will only support up to 2 high speed simultaneous output surfaces
+(preview and recording surfaces)
+in this mode.<wbr/> Above controls will be effective only if all of below conditions are true:</p>
+<ul>
+<li>The application creates a camera capture session with no more than 2 surfaces via
+<a href="https://developer.android.com/reference/android/hardware/camera2/CameraDevice.html#createConstrainedHighSpeedCaptureSession">CameraDevice#createConstrainedHighSpeedCaptureSession</a>.<wbr/> The
+targeted surfaces must be preview surface (either from
+<a href="https://developer.android.com/reference/android/view/SurfaceView.html">SurfaceView</a> or <a href="https://developer.android.com/reference/android/graphics/SurfaceTexture.html">SurfaceTexture</a>) or
+recording surface(either from <a href="https://developer.android.com/reference/android/media/MediaRecorder.html#getSurface">MediaRecorder#getSurface</a> or
+<a href="https://developer.android.com/reference/android/media/MediaCodec.html#createInputSurface">MediaCodec#createInputSurface</a>).<wbr/></li>
+<li>The stream sizes are selected from the sizes reported by
+<a href="https://developer.android.com/reference/android/hardware/camera2/params/StreamConfigurationMap.html#getHighSpeedVideoSizes">StreamConfigurationMap#getHighSpeedVideoSizes</a>.<wbr/></li>
+<li>The FPS ranges are selected from

+<a href="https://developer.android.com/reference/android/hardware/camera2/CameraDevice.html#createConstrainedHighSpeedCaptureSession">CameraDevice#createConstrainedHighSpeedCaptureSession</a>
+will fail.<wbr/></p>
+<p>Switching to a FPS range that has different maximum FPS may trigger some camera device
+reconfigurations,<wbr/> which may introduce extra latency.<wbr/> It is recommended that
+the application avoids unnecessary maximum target FPS changes as much as possible
+during high speed streaming.<wbr/></p></span>

+<li>Some hardware JPEG encoders may have pixel boundary alignment requirements,<wbr/> such as

+</ul>
+<p>Therefore,<wbr/> the maximum JPEG size may be smaller than sensor maximum resolution.<wbr/>
+However,<wbr/> the largest JPEG size must be as close as possible to the sensor maximum
+resolution given above constraints.<wbr/> It is required that after aspect ratio adjustments,<wbr/>
+additional size reduction due to other issues must be less than 3% in area.<wbr/> For example,<wbr/>
+if the sensor maximum resolution is 3280x2464,<wbr/> if the maximum JPEG size has aspect
+ratio 4:3,<wbr/> the JPEG encoder alignment requirement is 16,<wbr/> the maximum JPEG size will be

+the HAL must include all YUV_<wbr/>420_<wbr/>888 sizes that have JPEG sizes listed

+<p>It must also include each below resolution if it is smaller than or

+<li>720p (1280 x 720)</li>

+<p>For LIMITED capability devices
+(<code><a href="#static_android.info.supportedHardwareLevel">android.<wbr/>info.<wbr/>supported<wbr/>Hardware<wbr/>Level</a> == LIMITED</code>),<wbr/>

+              <p>A stall duration is how much extra time would get added
+to the normal minimum frame duration for a repeating request
+that has streams with non-zero stall.<wbr/></p>
+<p>For example,<wbr/> consider JPEG captures which have the following
+characteristics:</p>
+<ul>
+<li>JPEG streams act like processed YUV streams in requests for which
+they are not included; in requests in which they are directly
+referenced,<wbr/> they act as JPEG streams.<wbr/> This is because supporting a
+JPEG stream requires the underlying YUV data to always be ready for
+use by a JPEG encoder,<wbr/> but the encoder will only be used (and impact
+frame duration) on requests that actually reference a JPEG stream.<wbr/></li>
+<li>The JPEG processor can run concurrently to the rest of the camera
+pipeline,<wbr/> but cannot process more than 1 capture at a time.<wbr/></li>
+</ul>
+<p>In other words,<wbr/> using a repeating YUV request would result
+in a steady frame rate (let's say it's 30 FPS).<wbr/> If a single
+JPEG request is submitted periodically,<wbr/> the frame rate will stay
+at 30 FPS (as long as we wait for the previous JPEG to return each
+time).<wbr/> If we try to submit a repeating YUV + JPEG request,<wbr/> then
+the frame rate will drop from 30 FPS.<wbr/></p>
+<p>In general,<wbr/> submitting a new request with a non-0 stall time
+stream will <em>not</em> cause a frame rate drop unless there are still
+outstanding buffers for that stream from previous requests.<wbr/></p>
+<p>Submitting a repeating request with streams (call this <code>S</code>)
+is the same as setting the minimum frame duration from
+the normal minimum frame duration corresponding to <code>S</code>,<wbr/> added with
+the maximum stall duration for <code>S</code>.<wbr/></p>
+<p>If interleaving requests with and without a stall duration,<wbr/>
+a request will stall by the maximum of the remaining times
+for each can-stall stream with outstanding buffers.<wbr/></p>
+<p>This means that a stalling request will not have an exposure start
+until the stall has completed.<wbr/></p>
+<p>This should correspond to the stall duration when only that stream is
+active,<wbr/> with all processing (typically in android.<wbr/>*.<wbr/>mode) set to FAST
+or OFF.<wbr/> Setting any of the processing modes to HIGH_<wbr/>QUALITY
+effectively results in an indeterminate stall duration for all
+streams in a request (the regular stall calculation rules are
+ignored).<wbr/></p>
+<p>The following formats may always have a stall duration:</p>
+<ul>
+<li><a href="https://developer.android.com/reference/android/graphics/ImageFormat.html#JPEG">ImageFormat#JPEG</a></li>
+<li><a href="https://developer.android.com/reference/android/graphics/ImageFormat.html#RAW_SENSOR">ImageFormat#RAW_<wbr/>SENSOR</a></li>
+</ul>
+<p>The following formats will never have a stall duration:</p>

+<p>*1: For JPEG format,<wbr/> the sizes may be restricted by below conditions:</p>
+<ul>
+<li>The HAL may choose the aspect ratio of each Jpeg size to be one of well known ones
+(e.<wbr/>g.<wbr/> 4:3,<wbr/> 16:9,<wbr/> 3:2 etc.<wbr/>).<wbr/> If the sensor maximum resolution
+(defined by <a href="#static_android.sensor.info.activeArraySize">android.<wbr/>sensor.<wbr/>info.<wbr/>active<wbr/>Array<wbr/>Size</a>) has an aspect ratio other than these,<wbr/>

+<li>Some hardware JPEG encoders may have pixel boundary alignment requirements,<wbr/> such as
+the dimensions being a multiple of 16.<wbr/>
+Therefore,<wbr/> the maximum JPEG size may be smaller than sensor maximum resolution.<wbr/>
+However,<wbr/> the largest JPEG size will be as close as possible to the sensor maximum
+resolution given above constraints.<wbr/> It is required that after aspect ratio adjustments,<wbr/>
+additional size reduction due to other issues must be less than 3% in area.<wbr/> For example,<wbr/>
+if the sensor maximum resolution is 3280x2464,<wbr/> if the maximum JPEG size has aspect

+              <p>The maximum frame rate that can be supported by a camera subsystem is
+a function of many factors:</p>
+<ul>
+<li>Requested resolutions of output image streams</li>
+<li>Availability of binning /<wbr/> skipping modes on the imager</li>
+<li>The bandwidth of the imager interface</li>
+<li>The bandwidth of the various ISP processing blocks</li>
+</ul>
+<p>Since these factors can vary greatly between different ISPs and
+sensors,<wbr/> the camera abstraction tries to represent the bandwidth
+restrictions with as simple a model as possible.<wbr/></p>
+<p>The model presented has the following characteristics:</p>
+<ul>
+<li>The image sensor is always configured to output the smallest
+resolution possible given the application's requested output stream
+sizes.<wbr/>  The smallest resolution is defined as being at least as large
+as the largest requested output stream size; the camera pipeline must
+never digitally upsample sensor data when the crop region covers the
+whole sensor.<wbr/> In general,<wbr/> this means that if only small output stream
+resolutions are configured,<wbr/> the sensor can provide a higher frame
+rate.<wbr/></li>
+<li>Since any request may use any or all the currently configured
+output streams,<wbr/> the sensor and ISP must be configured to support
+scaling a single capture to all the streams at the same time.<wbr/>  This
+means the camera pipeline must be ready to produce the largest
+requested output size without any delay.<wbr/>  Therefore,<wbr/> the overall
+frame rate of a given configured stream set is governed only by the
+largest requested stream resolution.<wbr/></li>
+<li>Using more than one output stream in a request does not affect the
+frame duration.<wbr/></li>
+<li>Certain format-streams may need to do additional background processing
+before data is consumed/<wbr/>produced by that stream.<wbr/> These processors
+can run concurrently to the rest of the camera pipeline,<wbr/> but
+cannot process more than 1 capture at a time.<wbr/></li>
+</ul>
+<p>The necessary information for the application,<wbr/> given the model above,<wbr/>
+is provided via the <a href="#static_android.scaler.streamConfigurationMap">android.<wbr/>scaler.<wbr/>stream<wbr/>Configuration<wbr/>Map</a> field using
+<a href="https://developer.android.com/reference/android/hardware/camera2/params/StreamConfigurationMap.html#getOutputMinFrameDuration">StreamConfigurationMap#getOutputMinFrameDuration</a>.<wbr/>
+These are used to determine the maximum frame rate /<wbr/> minimum frame
+duration that is possible for a given stream configuration.<wbr/></p>
+<p>Specifically,<wbr/> the application can use the following rules to
+determine the minimum frame duration it can request from the camera
+device:</p>
+<ol>
+<li>Let the set of currently configured input/<wbr/>output streams
+be called <code>S</code>.<wbr/></li>
+<li>Find the minimum frame durations for each stream in <code>S</code>,<wbr/> by looking
+it up in <a href="#static_android.scaler.streamConfigurationMap">android.<wbr/>scaler.<wbr/>stream<wbr/>Configuration<wbr/>Map</a> using <a href="https://developer.android.com/reference/android/hardware/camera2/params/StreamConfigurationMap.html#getOutputMinFrameDuration">StreamConfigurationMap#getOutputMinFrameDuration</a>
+(with its respective size/<wbr/>format).<wbr/> Let this set of frame durations be
+called <code>F</code>.<wbr/></li>
+<li>For any given request <code>R</code>,<wbr/> the minimum frame duration allowed
+for <code>R</code> is the maximum out of all values in <code>F</code>.<wbr/> Let the streams
+used in <code>R</code> be called <code>S_<wbr/>r</code>.<wbr/></li>
+</ol>
+<p>If none of the streams in <code>S_<wbr/>r</code> have a stall time (listed in <a href="https://developer.android.com/reference/android/hardware/camera2/params/StreamConfigurationMap.html#getOutputStallDuration">StreamConfigurationMap#getOutputStallDuration</a>
+using its respective size/<wbr/>format),<wbr/> then the frame duration in <code>F</code>
+determines the steady state frame rate that the application will get
+if it uses <code>R</code> as a repeating request.<wbr/> Let this special kind of
+request be called <code>Rsimple</code>.<wbr/></p>
+<p>A repeating request <code>Rsimple</code> can be <em>occasionally</em> interleaved
+by a single capture of a new request <code>Rstall</code> (which has at least
+one in-use stream with a non-0 stall time) and if <code>Rstall</code> has the
+same minimum frame duration this will not cause a frame rate loss
+if all buffers from the previous <code>Rstall</code> have already been
+delivered.<wbr/></p>

+              <p>The maximum frame rate that can be supported by a camera subsystem is
+a function of many factors:</p>
+<ul>
+<li>Requested resolutions of output image streams</li>
+<li>Availability of binning /<wbr/> skipping modes on the imager</li>
+<li>The bandwidth of the imager interface</li>
+<li>The bandwidth of the various ISP processing blocks</li>
+</ul>
+<p>Since these factors can vary greatly between different ISPs and
+sensors,<wbr/> the camera abstraction tries to represent the bandwidth
+restrictions with as simple a model as possible.<wbr/></p>
+<p>The model presented has the following characteristics:</p>
+<ul>
+<li>The image sensor is always configured to output the smallest
+resolution possible given the application's requested output stream
+sizes.<wbr/>  The smallest resolution is defined as being at least as large
+as the largest requested output stream size; the camera pipeline must
+never digitally upsample sensor data when the crop region covers the
+whole sensor.<wbr/> In general,<wbr/> this means that if only small output stream
+resolutions are configured,<wbr/> the sensor can provide a higher frame
+rate.<wbr/></li>
+<li>Since any request may use any or all the currently configured
+output streams,<wbr/> the sensor and ISP must be configured to support
+scaling a single capture to all the streams at the same time.<wbr/>  This
+means the camera pipeline must be ready to produce the largest
+requested output size without any delay.<wbr/>  Therefore,<wbr/> the overall
+frame rate of a given configured stream set is governed only by the
+largest requested stream resolution.<wbr/></li>
+<li>Using more than one output stream in a request does not affect the
+frame duration.<wbr/></li>
+<li>Certain format-streams may need to do additional background processing
+before data is consumed/<wbr/>produced by that stream.<wbr/> These processors
+can run concurrently to the rest of the camera pipeline,<wbr/> but
+cannot process more than 1 capture at a time.<wbr/></li>
+</ul>
+<p>The necessary information for the application,<wbr/> given the model above,<wbr/>
+is provided via the <a href="#static_android.scaler.streamConfigurationMap">android.<wbr/>scaler.<wbr/>stream<wbr/>Configuration<wbr/>Map</a> field using
+<a href="https://developer.android.com/reference/android/hardware/camera2/params/StreamConfigurationMap.html#getOutputMinFrameDuration">StreamConfigurationMap#getOutputMinFrameDuration</a>.<wbr/>
+These are used to determine the maximum frame rate /<wbr/> minimum frame
+duration that is possible for a given stream configuration.<wbr/></p>
+<p>Specifically,<wbr/> the application can use the following rules to
+determine the minimum frame duration it can request from the camera
+device:</p>
+<ol>
+<li>Let the set of currently configured input/<wbr/>output streams
+be called <code>S</code>.<wbr/></li>
+<li>Find the minimum frame durations for each stream in <code>S</code>,<wbr/> by looking
+it up in <a href="#static_android.scaler.streamConfigurationMap">android.<wbr/>scaler.<wbr/>stream<wbr/>Configuration<wbr/>Map</a> using <a href="https://developer.android.com/reference/android/hardware/camera2/params/StreamConfigurationMap.html#getOutputMinFrameDuration">StreamConfigurationMap#getOutputMinFrameDuration</a>
+(with its respective size/<wbr/>format).<wbr/> Let this set of frame durations be
+called <code>F</code>.<wbr/></li>
+<li>For any given request <code>R</code>,<wbr/> the minimum frame duration allowed
+for <code>R</code> is the maximum out of all values in <code>F</code>.<wbr/> Let the streams
+used in <code>R</code> be called <code>S_<wbr/>r</code>.<wbr/></li>
+</ol>
+<p>If none of the streams in <code>S_<wbr/>r</code> have a stall time (listed in <a href="https://developer.android.com/reference/android/hardware/camera2/params/StreamConfigurationMap.html#getOutputStallDuration">StreamConfigurationMap#getOutputStallDuration</a>
+using its respective size/<wbr/>format),<wbr/> then the frame duration in <code>F</code>
+determines the steady state frame rate that the application will get
+if it uses <code>R</code> as a repeating request.<wbr/> Let this special kind of
+request be called <code>Rsimple</code>.<wbr/></p>
+<p>A repeating request <code>Rsimple</code> can be <em>occasionally</em> interleaved
+by a single capture of a new request <code>Rstall</code> (which has at least
+one in-use stream with a non-0 stall time) and if <code>Rstall</code> has the
+same minimum frame duration this will not cause a frame rate loss
+if all buffers from the previous <code>Rstall</code> have already been
+delivered.<wbr/></p>

+<p>The green split is calculated as follows:</p>
+<ol>
+<li>A 5x5 pixel (or larger) window W within the active sensor array is
+chosen.<wbr/> The term 'pixel' here is taken to mean a group of 4 Bayer
+mosaic channels (R,<wbr/> Gr,<wbr/> Gb,<wbr/> B).<wbr/>  The location and size of the window
+chosen is implementation defined,<wbr/> and should be chosen to provide a
+green split estimate that is both representative of the entire image
+for this camera sensor,<wbr/> and can be calculated quickly.<wbr/></li>
+<li>The arithmetic mean of the green channels from the red
+rows (mean_<wbr/>Gr) within W is computed.<wbr/></li>
+<li>The arithmetic mean of the green channels from the blue
+rows (mean_<wbr/>Gb) within W is computed.<wbr/></li>
+<li>The maximum ratio R of the two means is computed as follows:
+<code>R = max((mean_<wbr/>Gr + 1)/<wbr/>(mean_<wbr/>Gb + 1),<wbr/> (mean_<wbr/>Gb + 1)/<wbr/>(mean_<wbr/>Gr + 1))</code></li>

+<p>The ratio R is the green split divergence reported for this property,<wbr/>
+which represents how much the green channels differ in the mosaic
+pattern.<wbr/>  This value is typically used to determine the treatment of
+the green mosaic channels when demosaicing.<wbr/></p>
+<p>The green split value can be roughly interpreted as follows:</p>
+<ul>
+<li>R &lt; 1.<wbr/>03 is a negligible split (&lt;3% divergence).<wbr/></li>
+<li>1.<wbr/>20 &lt;= R &gt;= 1.<wbr/>03 will require some software
+correction to avoid demosaic errors (3-20% divergence).<wbr/></li>
+<li>R &gt; 1.<wbr/>20 will require strong software correction to produce

+</ul>
+<p>And the exposure change in Request 4 requires the camera

+<ul>
+<li>Result 1: Exposure = 10ms,<wbr/> Black level lock = OFF</li>

+              <p>When a request is submitted to the camera device,<wbr/> there is usually a
+delay of several frames before the controls get applied.<wbr/> A camera
+device may either choose to account for this delay by implementing a
+pipeline and carefully submit well-timed atomic control updates,<wbr/> or
+it may start streaming control changes that span over several frame
+boundaries.<wbr/></p>
+<p>In the latter case,<wbr/> whenever a request's settings change relative to
+the previous submitted request,<wbr/> the full set of changes may take
+multiple frame durations to fully take effect.<wbr/> Some settings may
+take effect sooner (in less frame durations) than others.<wbr/></p>
+<p>While a set of control changes are being propagated,<wbr/> this value
+will be CONVERGING.<wbr/></p>
+<p>Once it is fully known that a set of control changes have been
+finished propagating,<wbr/> and the resulting updated control settings
+have been read back by the camera device,<wbr/> this value will be set
+to a non-negative frame number (corresponding to the request to
+which the results have synchronized to).<wbr/></p>
+<p>Older camera device implementations may not have a way to detect
+when all camera controls have been applied,<wbr/> and will always set this
+value to UNKNOWN.<wbr/></p>
+<p>FULL capability devices will always have this value set to the
+frame number of the request corresponding to this result.<wbr/></p>
+<p><em>Further details</em>:</p>
+<ul>
+<li>Whenever a request differs from the last request,<wbr/> any future
+results not yet returned may have this value set to CONVERGING (this
+could include any in-progress captures not yet returned by the camera
+device,<wbr/> for more details see pipeline considerations below).<wbr/></li>
+<li>Submitting a series of multiple requests that differ from the
+previous request (e.<wbr/>g.<wbr/> r1,<wbr/> r2,<wbr/> r3 s.<wbr/>t.<wbr/> r1 != r2 != r3)
+moves the new synchronization frame to the last non-repeating
+request (using the smallest frame number from the contiguous list of
+repeating requests).<wbr/></li>
+<li>Submitting the same request repeatedly will not change this value
+to CONVERGING,<wbr/> if it was already a non-negative value.<wbr/></li>
+<li>When this value changes to non-negative,<wbr/> that means that all of the
+metadata controls from the request have been applied,<wbr/> all of the
+metadata controls from the camera device have been read to the
+updated values (into the result),<wbr/> and all of the graphics buffers
+corresponding to this result are also synchronized to the request.<wbr/></li>
+</ul>
+<p><em>Pipeline considerations</em>:</p>
+<p>Submitting a request with updated controls relative to the previously
+submitted requests may also invalidate the synchronization state
+of all the results corresponding to currently in-flight requests.<wbr/></p>
+<p>In other words,<wbr/> results for this current request and up to
+<a href="#static_android.request.pipelineMaxDepth">android.<wbr/>request.<wbr/>pipeline<wbr/>Max<wbr/>Depth</a> prior requests may have their

+## Camera Metadata Interface ##
+---
+
+## Overview: ##
+
+The camera.metadata interface is used by the Android camera service,
+camera provider and camera devices to retrieve static camera information and issue
+camera capture controls.
+
+See the docs.html for each version for the detailed description of each metadata
+specification.
+## Version history: ##
+
+### @3.2:
+
+HIDL version of the baseline camera metadata interface, required by
+camera.provider@2.4 and camera.device@3.2 onwards.

+ *
+ * Multiple camera provider HALs may be present in a single system.
+ * For discovery, the service names, and process names, must be of the form

+ *   - <major>/<minor> is the provider HAL HIDL version,

+ *   - <instance> is a non-negative integer starting from 0 to disambiguate
+ *     between multiple HALs of the same type.
+ *
+ * The "legacy" type is only used for passthrough legacy HAL mode, and must
+ * not be used by a standalone binderized HAL.
+ *
+ * The device instance names enumerated by the provider must be of the form

+ * <major>/<minor> is the HIDL version of the interface. <id> is either a small
+ * incrementing integer for "internal" device types, with 0 being the main
+ * back-facing camera and 1 being the main front-facing camera, if they exist.
+ * Or, for external devices such as type "usb", a unique serial number that can
+ * be used to identify the device reliably when it is disconnected and

+## Camera Provider HAL ##
+---
+
+## Overview: ##
+
+The camera.provider HAL is used by the Android camera service to discover,
+query, and open individual camera devices.
+
+It also allows for direct control of the flash unit of camera devices that have
+one, for turning on/off torch mode.
+
+More complete information about the Android camera HAL and subsystem can be found at
+[source.android.com](http://source.android.com/devices/camera/index.html).
+
+## Version history: ##
+
+## types.hal: ##
+
+### @0.0:
+
+Common enum and struct definitions for all camera HAL interfaces. Does not
+define any interfaces of its own.
+
+## ICameraProvider.hal: ##
+
+### @2.4:
+
+First HIDL version of the camera provider HAL, closely matching the feature set
+and operation of the pre-HIDL camera HAL module v2.4.
+
+## ICameraProviderCallback.hal: ##
+
+### @2.4:
+
+First HIDL version of the camara provider HAL callback interface, closely
+matching the feature set and operation of the pre-HIDL camera HAL module
+callbacks v2.4.

+ * Outside state: We are 95% confident that the user is outside the geofence
+ * Unknown state: Rest of the time.
+ *
+ * The Unknown state is better explained with an example:
+ *
+ *                            __________
+ *                           |         c|

+ *                            """"""""""
+ * In the diagram above, "a" and "b" are 2 geofences and "c" is the accuracy
+ * circle reported by the GNSS subsystem. Now with regard to "b", the system is
+ * confident that the user is outside. But with regard to "a" is not confident
+ * whether it is inside or outside the geofence. If the accuracy remains the
+ * same for a sufficient period of time, the UNCERTAIN transition must be
+ * triggered with the state set to Unknown. If the accuracy improves later, an
+ * appropriate transition must be triggered.  This "sufficient period of time"
+ * is defined by the parameter in the addGeofenceArea API.
+ * In other words, Unknown state can be interpreted as a state in which the
+ * GNSS subsystem isn't confident enough that the user is either inside or
+ * outside the Geofence. It moves to Unknown state only after the expiry of the
+ * timeout.
+ *
+ * The geofence callback needs to be triggered for the ENTERED and EXITED
+ * transitions, when the GNSS system is confident that the user has entered
+ * (Inside state) or exited (Outside state) the Geofence. An implementation
+ * which uses a value of 95% as the confidence is recommended. The callback
+ * must be triggered only for the transitions requested by the
+ * addGeofenceArea method.
+ *
+ * Even though the diagram and explanation talks about states and transitions,
+ * the callee is only interested in the transitions. The states are mentioned
+ * here for illustrative purposes.
+ *
+ * Startup Scenario: When the device boots up, if an application adds geofences,
+ * and then we get an accurate GNSS location fix, it needs to trigger the
+ * appropriate (ENTERED or EXITED) transition for every Geofence it knows about.
+ * By default, all the Geofences will be in the Unknown state.
+ *
+ * When the GNSS system is unavailable, gnssGeofenceStatusCb must be
+ * called to inform the upper layers of the same. Similarly, when it becomes
+ * available the callback must be called. This is a global state while the
+ * UNKNOWN transition described above is per geofence.
+ *
+ * An important aspect to note is that users of this API (framework), will use
+ * other subsystems like wifi, sensors, cell to handle Unknown case and
+ * hopefully provide a definitive state transition to the third party
+ * application. GNSS Geofence will just be a signal indicating what the GNSS
+ * subsystem knows about the Geofence.

+ * Color modes that may be supported by a display.
+ *
+ * Definitions:
+ * Rendering intent generally defines the goal in mapping a source (input)
+ * color to a destination device color for a given color mode.
+ *
+ *  It is important to keep in mind three cases where mapping may be applied:
+ *  1. The source gamut is much smaller than the destination (display) gamut
+ *  2. The source gamut is much larger than the destination gamut (this will
+ *  ordinarily be handled using colorimetric rendering, below)
+ *  3. The source and destination gamuts are roughly equal, although not
+ *  completely overlapping
+ *  Also, a common requirement for mappings is that skin tones should be
+ *  preserved, or at least remain natural in appearance.
+ *
+ *  Colorimetric Rendering Intent (All cases):
+ *  Colorimetric indicates that colors should be preserved. In the case
+ *  that the source gamut lies wholly within the destination gamut or is
+ *  about the same (#1, #3), this will simply mean that no manipulations
+ *  (no saturation boost, for example) are applied. In the case where some
+ *  source colors lie outside the destination gamut (#2, #3), those will
+ *  need to be mapped to colors that are within the destination gamut,
+ *  while the already in-gamut colors remain unchanged.
+ *
+ *  Non-colorimetric transforms can take many forms. There are no hard
+ *  rules and it's left to the implementation to define.
+ *  Two common intents are described below.
+ *
+ *  Stretched-Gamut Enhancement Intent (Source < Destination):
+ *  When the destination gamut is much larger than the source gamut (#1), the
+ *  source primaries may be redefined to reflect the full extent of the
+ *  destination space, or to reflect an intermediate gamut.
+ *  Skin-tone preservation would likely be applied. An example might be sRGB
+ *  input displayed on a DCI-P3 capable device, with skin-tone preservation.
+ *
+ *  Within-Gamut Enhancement Intent (Source >= Destination):
+ *  When the device (destination) gamut is not larger than the source gamut
+ *  (#2 or #3), but the appearance of a larger gamut is desired, techniques
+ *  such as saturation boost may be applied to the source colors. Skin-tone
+ *  preservation may be applied. There is no unique method for within-gamut
+ *  enhancement; it would be defined within a flexible color mode.

+     *   setLayerSourceCrop(FRect crop);
+     *
+     * Sets the source crop (the portion of the source buffer which will fill
+     * the display frame) of the given layer. This crop rectangle must not
+     * exceed the dimensions of the latched buffer.
+     *
+     * If the device is not capable of supporting a true float source crop
+     * (i.e., it will truncate or round the floats to integers), it must set
+     * this layer to Composition::CLIENT when crop is non-integral for the
+     * most accurate rendering.
+     *
+     * If the device cannot support float source crops, but still wants to
+     * handle the layer, it must use the following code (or similar) to
+     * convert to an integer crop:
+     *   intCrop.left = (int) ceilf(crop.left);
+     *   intCrop.top = (int) ceilf(crop.top);
+     *   intCrop.right = (int) floorf(crop.right);

+     *
+     *   setLayerVisibleRegion(vec<Rect> visible);
+     *
+     * Specifies the portion of the layer that is visible, including portions
+     * under translucent areas of other layers. The region is in screen space,
+     * and must not exceed the dimensions of the screen.
+     *
+     * @param visible is the new visible region, in screen space.

+     *
+     * SET_LAYER_Z_ORDER has this pseudo prototype
+     *
+     *   setLayerZOrder(uint32_t z);

+ * a process, but not mapped in to that process's address space.
+ * A secondary goal is to be able to categorize memory used by a process into
+ * GL, graphics, etc. All memory sizes must be in real memory usage,
+ * accounting for stride, bit depth, rounding up to page size, etc.
+ *
+ * Constructor for the interface should be used to perform memtrack management
+ * setup actions and is called once before any calls to getMemory().
+ */

+     * getMemory() populates MemtrackRecord vector with the sizes of memory

+     *
+     * This function must be thread-safe, it may get called from multiple
+     * threads at the same time.
+     *
+     * A process collecting memory statistics will call getMemory for each
+     * combination of pid and memory type. For each memory type that it
+     * recognizes, the HAL must fill out an array of memtrack_record
+     * structures breaking down the statistics of that memory type as much as
+     * possible. For example,
+     * getMemory(<pid>, GL) might return:
+     * { { 4096,  ACCOUNTED | PRIVATE | SYSTEM },
+     *   { 40960, UNACCOUNTED | PRIVATE | SYSTEM },
+     *   { 8192,  ACCOUNTED | PRIVATE | DEDICATED },
+     *   { 8192,  UNACCOUNTED | PRIVATE | DEDICATED } }
+     * If the HAL cannot differentiate between SYSTEM and DEDICATED memory, it
+     * could return:
+     * { { 12288,  ACCOUNTED | PRIVATE },
+     *   { 49152,  UNACCOUNTED | PRIVATE } }
+     *
+     * Memory must not overlap between types. For example, a graphics buffer
+     * that has been mapped into the GPU as a surface must show up when
+     * GRAPHICS is requested and not when GL
+     * is requested.
+     *
+     * @param pid process for which memory information is requested
+     * @param type memory type that information is being requested about
+     * @return records vector of MemtrackRecord containing memory information

+     * supported.

+ * Sensor type
+ *
+ * Each sensor has a type which defines what this sensor measures and how
+ * measures are reported. See the Base sensors and Composite sensors lists
+ * for complete descriptions:
+ * http://source.android.com/devices/sensors/base_triggers.html
+ * http://source.android.com/devices/sensors/composite_sensors.html
+ *
+ * Device manufacturers (OEMs) can define their own sensor types, for
+ * their private use by applications or services provided by them. Such
+ * sensor types are specific to an OEM and can't be exposed in the SDK.
+ * These types must start at SensorType::DEVICE_PRIVATE_BASE.
+ *
+ * All sensors defined outside of the device private range must correspond to
+ * a type defined in this file, and must satisfy the characteristics listed in
+ * the description of the sensor type.
+ *
+ * Each sensor also has a "typeAsString".
+ *  - string type of sensors defined in this file is overridden by Android to
+ *    values defined in Android API with "android.sensor." prefix.
+ *    Example: for an accelerometer,
+ *      type = SensorType::Acclerometer
+ *      typeAsString = "" (will be replace by "android.sensor.accelerometer" by
+ *                         Android frameowrk)
+ *  - string type of sensors inside of the device private range MUST be prefixed
+ *    by the sensor provider's or OEM reverse domain name. In particular, they
+ *    cannot use the "android.sensor." prefix.
+ *
+ * When android introduces a new sensor type that can replace an OEM-defined
+ * sensor type, the OEM must use the official sensor type and stringType on
+ * versions of the HAL that support this new official sensor type.
+ *
+ * Example (made up): Suppose Google's Glass team wants to surface a sensor
+ * detecting that Glass is on a head.
+ *  - Such a sensor is not officially supported in android KitKat
+ *  - Glass devices launching on KitKat can implement a sensor with
+ *      type = 0x10001
+ *      typeAsString = "com.google.glass.onheaddetector"
+ *  - In L android release, if android decides to define
+ *    SensorType::ON_HEAD_DETECTOR and STRING_SensorType::ON_HEAD_DETECTOR,
+ *    those types should replace the Glass-team-specific types in all future
+ *    launches.
+ *  - When launching Glass on the L release, Google should now use the official
+ *    type (SensorType::ON_HEAD_DETECTOR) and stringType.
+ *  - This way, all applications can now use this sensor.

+ * Wake up sensors.
+ * Each sensor may have either or both a wake-up and a non-wake variant.
+ * When registered in batch mode, wake-up sensors will wake up the AP when
+ * their FIFOs are full or when the batch timeout expires. A separate FIFO has
+ * to be maintained for wake up sensors and non wake up sensors. The non
+ * wake-up sensors need to overwrite their FIFOs when they are full till the AP
+ * wakes up and the wake-up sensors will wake-up the AP when their FIFOs are
+ * full or when the batch timeout expires without losing events.
+ * Wake-up and non wake-up variants of each sensor can be activated at
+ * different rates independently of each other.
+ *
+ * Note: Proximity sensor and significant motion sensor which were defined in
+ * previous releases are also wake-up sensors and must be treated as such.
+ * Wake-up one-shot sensors like SIGNIFICANT_MOTION cannot be batched, hence
+ * the text about batch above doesn't apply to them. See the definitions of
+ * SensorType::PROXIMITY and SensorType::SIGNIFICANT_MOTION for more info.
+ *
+ * Set SENSOR_FLAG_WAKE_UP flag for all wake-up sensors.
+ *
+ * For example, A device can have two sensors both of SensorType::ACCELEROMETER
+ * and one of them can be a wake_up sensor (with SENSOR_FLAG_WAKE_UP flag set)
+ * and the other can be a regular non wake_up sensor. Both of these sensors

+     * successful; flush() also has to generate flush complete event as if this
+     * is a sensor that does not support batching.
+     *
+     * A dynamic sensor connection indicates connection of a physical device or
+     * instantiation of a virtual sensor backed by algorithm; and a dynamic
+     * sensor disconnection indicates the the opposite. A sensor event of
+     * DYNAMIC_SENSOR_META type should be delivered regardless of

+     * connection and disconnection. In the sensor event, besides the common

+     * status, handle of the sensor involved, pointer to sensor_t structure and
+     * a uuid field, must be populated.

+ * to VehiclePropertyValue, essentially this is a std::unique_ptr with custom

+ * objects will be deleted immediately once the go out of scope. There's no
+ * synchornization penalty for these objects since we do not store them in the
+ * pool.
+ *
+ * This class is thread-safe. Users can obtain an object in one thread and pass
+ * it to another.
+ *
+ * Sample usage:
+ *
+ *   VehiclePropValuePool pool;
+ *   auto v = pool.obtain(VehiclePropertyType::INT32);
+ *   v->propId = VehicleProperty::HVAC_FAN_SPEED;
+ *   v->areaId = VehicleAreaZone::ROW_1_LEFT;
