+ * Inside state: We are 95% confident that the user is inside the geofence.
+ * 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 transistions. 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.

+ * pattern occupying unique byte addresses and with consistent byte offsets
+ * between neighboring pixels.
+ *
+ * The FlexLayout structure is used with any pixel format that can be
+ * represented by it, such as:
+ *
+ *  - PixelFormat::YCbCr_*_888
+ *  - PixelFormat::FLEX_RGB*_888
+ *  - PixelFormat::RGB[AX]_888[8],BGRA_8888,RGB_888

+ *  - even implementation defined formats that can be represented by the
+ *    structures
+ *
+ * Vertical increment (aka. row increment or stride) describes the distance in
+ * bytes from the first pixel of one row to the first pixel of the next row
+ * (below) for the component plane. This can be negative.
+ *
+ * Horizontal increment (aka. column or pixel increment) describes the
+ * distance in bytes from one pixel to the next pixel (to the right) on the
+ * same row for the component plane. This can be negative.
+ *
+ * Each plane can be subsampled either vertically or horizontally by a
+ * power-of-two factor.
+ *
+ * The bit-depth of each component can be arbitrary, as long as the pixels are
+ * laid out on whole bytes, in native byte-order, using the most significant
+ * bits of each unit.

+ * The Memory Tracker HAL is designed to return information about

+ * trackable in any other way, for example texture memory that is allocated by
+ * 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
+     * plus associated flags for that 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
+     * @return retval SUCCESS on success, TYPE_NOT_FOUND if the type is not
+     * 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 SENSOR_TYPE_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".
+ *  - StringType 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.
+ *  - StringType of sensors outside of the device private range MUST correspond
+ *    to the one defined in this file (starting with "android.sensor").
+ *    For example, accelerometers must have
+ *      type=SENSOR_TYPE_ACCELEROMETER and
+ *      stringType=SENSOR_STRING_TYPE_ACCELEROMETER
+ *
+ * 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 and stringType = "com.google.glass.onheaddetector"
+ *  - In L android release, if android decides to define
+ *    SENSOR_TYPE_ON_HEAD_DETECTOR and STRING_SENSOR_TYPE_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 (SENSOR_TYPE_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 should 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
+ * SENSOR_TYPE_PROXIMITY and SENSOR_TYPE_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 SENSOR_TYPE_ACCELEROMETER
+ * and one of them can be a wake_up sensor (with SENSOR_FLAG_WAKE_UP flag set)

+     * present in one sensor HAL implementation and presence of a sensor of this

+     * dynamic sensor feature. Operations, such as batch, activate and setDelay,
+     * to this special purpose sensor should be treated as no-op and return
+     * 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
+     * SENSOR_TYPE_DYNAMIC_SENSOR_META type should be delivered regardless of
+     * the activation status of the sensor in the event of dynamic sensor
+     * connection and disconnection. In the sensor event, besides the common
+     * data entries, "dynamic_sensor_meta", which includes fields for connection
+     * status, handle of the sensor involved, pointer to sensor_t structure and
+     * a uuid field, should be populated.
+     *
+     * At a dynamic sensor connection event, fields of sensor_t structure
+     * referenced by a pointer in dynamic_sensor_meta should be filled as if it
+     * was regular sensors. Sensor HAL is responsible for recovery of memory if
+     * the corresponding data is dynamicially allocated. However, the the
+     * pointer must be valid until the first activate call to the sensor
+     * reported in this connection event. At a dynamic sensor disconnection,
+     * the sensor_t pointer should be NULL.
+     *
+     * The sensor handle assigned to dynamic sensors should never be the same as
+     * that of any regular static sensors, and should be unique until next boot.
+     * In another word, if a handle h is used for a dynamic sensor A, that same
+     * number cannot be used for the same dynamic sensor A or another dynamic
+     * sensor B even after disconnection of A until reboot.
+     *
+     * The UUID field will be used for identifying the sensor in addition to
+     * name, vendor and version and type. For physical sensors of the same
+     * model, all sensors will have the same values in sensor_t, but the UUID
+     * should be unique and persistent for each individual unit. An all zero
