+# bootanimation format
+
+## zipfile paths
+
+The system selects a boot animation zipfile from the following locations, in order:
+
+    /system/media/bootanimation-encrypted.zip (if getprop("vold.decrypt") = '1')
+    /system/media/bootanimation.zip
+    /oem/media/bootanimation.zip
+
+## zipfile layout
+
+The `bootanimation.zip` archive file includes:
+
+    desc.txt - a text file
+    part0  \
+    part1   \  directories full of PNG frames
+    ...     /
+    partN  /
+
+## desc.txt format
+
+The first line defines the general parameters of the animation:
+
+    WIDTH HEIGHT FPS
+
+  * **WIDTH:** animation width (pixels)
+  * **HEIGHT:** animation height (pixels)
+  * **FPS:** frames per second, e.g. 60
+
+It is followed by a number of rows of the form:
+
+    TYPE COUNT PAUSE PATH [#RGBHEX CLOCK]
+
+  * **TYPE:** a single char indicating what type of animation segment this is:
+      + `p` -- this part will play unless interrupted by the end of the boot
+      + `c` -- this part will play to completion, no matter what
+  * **COUNT:** how many times to play the animation, or 0 to loop forever until boot is complete
+  * **PAUSE:** number of FRAMES to delay after this part ends
+  * **PATH:** directory in which to find the frames for this part (e.g. `part0`)
+  * **RGBHEX:** _(OPTIONAL)_ a background color, specified as `#RRGGBB`
+  * **CLOCK:** _(OPTIONAL)_ the y-coordinate at which to draw the current time (for watches)
+
+There is also a special TYPE, `$SYSTEM`, that loads `/system/media/bootanimation.zip`
+and plays that.
+
+## loading and playing frames
+
+Each part is scanned and loaded directly from the zip archive. Within a part directory, every file
+(except `trim.txt` and `audio.wav`; see next sections) is expected to be a PNG file that represents
+one frame in that part (at the specified resolution). For this reason it is important that frames be
+named sequentially (e.g. `part000.png`, `part001.png`, ...) and added to the zip archive in that
+order.
+
+## trim.txt
+
+To save on memory, textures may be trimmed by their background color.  trim.txt sequentially lists
+the trim output for each frame in its directory, so the frames may be properly positioned.
+Output should be of the form: `WxH+X+Y`. Example:
+
+    713x165+388+914
+    708x152+388+912
+    707x139+388+911
+    649x92+388+910
+
+If the file is not present, each frame is assumed to be the same size as the animation.
+
+## audio.wav
+
+Each part may optionally play a `wav` sample when it starts. To enable this, add a file
+with the name `audio.wav` in the part directory.
+
+## exiting
+
+The system will end the boot animation (first completing any incomplete or even entirely unplayed
+parts that are of type `c`) when the system is finished booting. (This is accomplished by setting
+the system property `service.bootanim.exit` to a nonzero string.)
+
+## protips
+
+### PNG compression
+
+Use `zopflipng` if you have it, otherwise `pngcrush` will do. e.g.:
+
+    for fn in *.png ; do
+        zopflipng -m ${fn}s ${fn}s.new && mv -f ${fn}s.new ${fn}
+        # or: pngcrush -q ....
+    done
+
+Some animations benefit from being reduced to 256 colors:
+
+    pngquant --force --ext .png *.png
+    # alternatively: mogrify -colors 256 anim-tmp/*/*.png
+
+### creating the ZIP archive
+
+    cd <path-to-pieces>
+    zip -0qry -i \*.txt \*.png \*.wav @ ../bootanimation.zip *.txt part*
+
+Note that the ZIP archive is not actually compressed! The PNG files are already as compressed
+as they can reasonably get, and there is unlikely to be any redundancy between files.

 /**
- * {@link ShortcutManager} manages shortcuts created by applications.
+ * The ShortcutManager manages "launcher shortcuts" (or simply "shortcuts").  Shortcuts provide
+ * users
+ * with quick access to activities other than an application's main activity in the currently-active
+ * launcher.  For example,
+ * an email application may publish the "compose new email" action, which will directly open the
+ * compose activity.  The {@link ShortcutInfo} class contains information about each of the
+ * shortcuts themselves.
  *
- * <h3>Dynamic shortcuts and pinned shortcuts</h3>
+ * <h3>Dynamic Shortcuts and Manifest Shortcuts</h3>
  *
- * An application can publish shortcuts with {@link #setDynamicShortcuts(List)} and
- * {@link #addDynamicShortcuts(List)}.  There can be at most
- * {@link #getMaxDynamicShortcutCount()} number of dynamic shortcuts at a time from the same
+ * There are two ways to publish shortcuts: manifest shortcuts and dynamic shortcuts.
+ *
+ * <ul>
+ * <li>Manifest shortcuts are declared in a resource
+ * XML, which is referenced in the publisher application's <code>AndroidManifest.xml</code> file.
+ * Manifest shortcuts are published when an application is installed,
+ * and the details of these shortcuts change when an application is upgraded with an updated XML
+ * file.
+ * Manifest shortcuts are immutable, and their
+ * definitions, such as icons and labels, cannot be changed dynamically without upgrading the
+ * publisher application.
+ *
+ * <li>Dynamic shortcuts are published at runtime using the {@link ShortcutManager} APIs.
+ * Applications can publish, update, and remove dynamic shortcuts at runtime.
+ * </ul>
+ *
+ * <p>Only "main" activities&mdash;activities that handle the {@code MAIN} action and the
+ * {@code LAUNCHER} category&mdash;can have shortcuts.
+ * If an application has multiple main activities, these activities will have different sets
+ * of shortcuts.
+ *
+ * <p>Dynamic shortcuts and manifest shortcuts are shown in the currently active launcher when
+ * the user long-presses on an application launcher icon.  The actual gesture may be different
+ * depending on the launcher application.
+ *
+ * <p>Each launcher icon can have at most {@link #getMaxShortcutCountPerActivity()} number of
+ * dynamic and manifest shortcuts combined.
+ *
+ *
+ * <h3>Pinning Shortcuts</h3>
+ *
+ * Launcher applications allow users to "pin" shortcuts so they're easier to access.  Both manifest
+ * and dynamic shortcuts can be pinned.
+ * Pinned shortcuts <b>cannot</b> be removed by publisher
+ * applications; they're removed only when the user removes them,
+ * when the publisher application is uninstalled, or when the
+ * user performs the "clear data" action on the publisher application from the device's Settings
  * application.
- * A dynamic shortcut can be deleted with {@link #removeDynamicShortcuts(List)}, and apps
- * can also use {@link #removeAllDynamicShortcuts()} to delete all dynamic shortcuts.
  *
- * <p>The shortcuts that are currently published by the above APIs are called "dynamic", because
- * they can be removed by the creator application at any time.  The user may "pin" dynamic shortcuts
- * on Launcher to make "pinned" shortcuts.  Pinned shortcuts <b>cannot</b> be removed by the creator
- * app.  An application can obtain all pinned shortcuts from itself with
- * {@link #getPinnedShortcuts()}.  Applications should keep the pinned shortcut information
- * up-to-date using {@link #updateShortcuts(List)}.
+ * <p>However, the publisher application can <em>disable</em> pinned shortcuts so they cannot be
+ * started.  See the following sections for details.
  *
- * <p>The number of pinned shortcuts does not affect the number of dynamic shortcuts that can be
- * published by an application at a time.
- * No matter how many pinned shortcuts that Launcher has for an application, the
- * application can still always publish {@link #getMaxDynamicShortcutCount()} number of dynamic
- * shortcuts.
  *
- * <h3>Shortcut IDs</h3>
+ * <h3>Updating and Disabling Shortcuts</h3>
  *
- * Each shortcut must have an ID, which must be unique within each application.  When a shortcut is
- * published, existing shortcuts with the same ID will be updated.  Note this may include a
- * pinned shortcut.
+ * <p>When a dynamic shortcut is pinned, even when the publisher removes it as a dynamic shortcut,
+ * the pinned shortcut will still be visible and launchable.  This allows an application to have
+ * more than {@link #getMaxShortcutCountPerActivity()} number of shortcuts.
  *
- * <h3>Rate limiting</h3>
+ * <p>For example, suppose {@link #getMaxShortcutCountPerActivity()} is 5:
+ * <ul>
+ *     <li>A chat application publishes 5 dynamic shortcuts for the 5 most recent
+ *     conversations, "c1" - "c5".
  *
- * Calls to {@link #setDynamicShortcuts(List)}, {@link #addDynamicShortcuts(List)},
- * and {@link #updateShortcuts(List)} from <b>background applications</b> will be
- * rate-limited.  An application can call these methods at most
- * {@link #getRemainingCallCount()} times until the rate-limiting counter is reset,
- * which happens at a certain time every day.
+ *     <li>The user pins all 5 of the shortcuts.
  *
- * <p>An application can use {@link #getRateLimitResetTime()} to get the next reset time.
+ *     <li>Later, the user has started 3 additional conversations ("c6", "c7", and "c8"),
+ *     so the publisher application
+ *     re-publishes its dynamic shortcuts.  The new dynamic shortcut list is:
+ *     "c4", "c5", "c6", "c7", and "c8".
+ *     The publisher application has to remove "c1", "c2", and "c3" because it can't have more than
+ *     5 dynamic shortcuts.
  *
- * <p>Foreground applications (i.e. ones with a foreground activity or a foreground services)
- * will not be throttled. Also, when an application comes to foreground,
- * {@link #getRemainingCallCount()} will be reset to the initial value.
+ *     <li>However, even though "c1", "c2" and "c3" are no longer dynamic shortcuts, the pinned
+ *     shortcuts for these conversations are still available and launchable.
  *
- * <p>For testing purposes, use "Developer Options" (found in the Settings menu) to reset the
- * internal rate-limiting counter.  Automated tests can use the following ADB shell command to
- * achieve the same effect:</p>
- * <pre>adb shell cmd shortcut reset-throttling</pre>
+ *     <li>At this point, the user can access a total of 8 shortcuts that link to activities in
+ *     the publisher application, including the 3 pinned
+ *     shortcuts, even though it's allowed to have at most 5 dynamic shortcuts.
+ *
+ *     <li>The application can use {@link #updateShortcuts(List)} to update any of the existing
+ *     8 shortcuts, when, for example, the chat peers' icons have changed.
+ * </ul>
+ * The {@link #addDynamicShortcuts(List)} and {@link #setDynamicShortcuts(List)} methods
+ * can also be used
+ * to update existing shortcuts with the same IDs, but they <b>cannot</b> be used
+ * for updating non-dynamic, pinned shortcuts because these two methods try to convert the given
+ * lists of shortcuts to dynamic shortcuts.
+ *
+ *
+ * <h4>Disabling Manifest Shortcuts</h4>
+ * When an application is upgraded and the new version
+ * no longer uses a manifest shortcut that appeared in the previous version, this deprecated
+ * shortcut will no longer be published as a manifest shortcut.
+ *
+ * <p>If the deprecated shortcut is pinned, then the pinned shortcut will remain on the launcher,
+ * but it will be disabled automatically.
+ * Note that, in this case, the pinned shortcut is no longer a manifest shortcut, but it's
+ * still <b>immutable</b> and cannot be updated using the {@link ShortcutManager} APIs.
+ *
+ *
+ * <h4>Disabling Dynamic Shortcuts</h4>
+ * Sometimes pinned shortcuts become obsolete and may not be usable.  For example, a pinned shortcut
+ * to a group chat will be unusable when the associated group chat is deleted.  In cases like this,
+ * applications should use {@link #disableShortcuts(List)}, which will remove the specified dynamic
+ * shortcuts and also make any specified pinned shortcuts un-launchable.
+ * The {@link #disableShortcuts(List, CharSequence)} method can also be used to disabled shortcuts
+ * and show users a custom error message when they attempt to launch the disabled shortcuts.
+ *
+ *
+ * <h3>Publishing Manifest Shortcuts</h3>
+ *
+ * In order to add manifest shortcuts to your application, first add
+ * {@code <meta-data android:name="android.app.shortcuts" />} to your main activity in
+ * AndroidManifest.xml:
+ * <pre>
+ * &lt;manifest xmlns:android=&quot;http://schemas.android.com/apk/res/android&quot;
+ *   package=&quot;com.example.myapplication&quot;&gt;
+ *   &lt;application . . .&gt;
+ *     &lt;activity android:name=&quot;Main&quot;&gt;
+ *       &lt;intent-filter&gt;
+ *         &lt;action android:name=&quot;android.intent.action.MAIN&quot; /&gt;
+ *         &lt;category android:name=&quot;android.intent.category.LAUNCHER&quot; /&gt;
+ *       &lt;/intent-filter&gt;
+ *       <b>&lt;meta-data android:name=&quot;android.app.shortcuts&quot; android:resource=&quot;@xml/shortcuts&quot;/&gt;</b>
+ *     &lt;/activity&gt;
+ *   &lt;/application&gt;
+ * &lt;/manifest&gt;
+ * </pre>
+ *
+ * Then, define your application's manifest shortcuts in the <code>res/xml/shortcuts.xml</code>
+ * file:
+ * <pre>
+ * &lt;shortcuts xmlns:android=&quot;http://schemas.android.com/apk/res/android&quot; &gt;
+ *   &lt;shortcut
+ *     android:shortcutId=&quot;compose&quot;
+ *     android:enabled=&quot;true&quot;
+ *     android:icon=&quot;@drawable/compose_icon&quot;
+ *     android:shortcutShortLabel=&quot;@string/compose_shortcut_short_label1&quot;
+ *     android:shortcutLongLabel=&quot;@string/compose_shortcut_long_label1&quot;
+ *     android:shortcutDisabledMessage=&quot;@string/compose_disabled_message1&quot;
+ *     &gt;
+ *     &lt;intent
+ *       android:action=&quot;android.intent.action.VIEW&quot;
+ *       android:targetPackage=&quot;com.example.myapplication&quot;
+ *       android:targetClass=&quot;com.example.myapplication.ComposeActivity&quot; /&gt;
+ *     &lt;!-- more intents can go here; see below --&gt;
+ *     &lt;categories android:name=&quot;android.shortcut.conversation&quot; /&gt;
+ *   &lt;/shortcut&gt;
+ *   &lt;!-- more shortcuts can go here --&gt;
+ * &lt;/shortcuts&gt;
+ * </pre>
+ *
+ * The following list includes descriptions for the different attributes within a manifest shortcut:
+ * <dl>
+ *   <dt>android:shortcutId</dt>
+ *   <dd>Mandatory shortcut ID</dd>
+ *
+ *   <dt>android:enabled</dt>
+ *   <dd>Default is {@code true}.  Can be set to {@code false} in order
+ *   to disable a manifest shortcut that was published in a previous version and and set a custom
+ *   disabled message.  If a custom disabled message is not needed, then a manifest shortcut can
+ *   be simply removed from the XML file rather than keeping it with {@code enabled="false"}.</dd>
+ *
+ *   <dt>android:icon</dt>
+ *   <dd>Shortcut icon.</dd>
+ *
+ *   <dt>android:shortcutShortLabel</dt>
+ *   <dd>Mandatory shortcut short label.
+ *   See {@link ShortcutInfo.Builder#setShortLabel(CharSequence)}.</dd>
+ *
+ *   <dt>android:shortcutLongLabel</dt>
+ *   <dd>Shortcut long label.
+ *   See {@link ShortcutInfo.Builder#setLongLabel(CharSequence)}.</dd>
+ *
+ *   <dt>android:shortcutDisabledMessage</dt>
+ *   <dd>When {@code android:enabled} is set to
+ *   {@code false}, this attribute is used to display a custom disabled message.</dd>
+ *
+ *   <dt>intent</dt>
+ *   <dd>Intent to launch when the user selects the shortcut.
+ *   {@code android:action} is mandatory.
+ *   See <a href="{@docRoot}guide/topics/ui/settings.html#Intents">Using intents</a> for the
+ *   other supported tags.
+ *   You can provide multiple intents for a single shortcut so that an activity is launched
+ *   with other activities in the back stack. See {@link android.app.TaskStackBuilder} for details.
+ *   </dd>
+ *   <dt>categories</dt>
+ *   <dd>Specify shortcut categories.  Currently only
+ *   {@link ShortcutInfo#SHORTCUT_CATEGORY_CONVERSATION} is defined in the framework.
+ *   </dd>
+ * </dl>
+ *
+ * <h3>Publishing Dynamic Shortcuts</h3>
+ *
+ * Applications can publish dynamic shortcuts with {@link #setDynamicShortcuts(List)}
+ * or {@link #addDynamicShortcuts(List)}.  The {@link #updateShortcuts(List)} method can also be
+ * used to update existing, mutable shortcuts.
+ * Use {@link #removeDynamicShortcuts(List)} or {@link #removeAllDynamicShortcuts()} to remove
+ * dynamic shortcuts.
+ *
+ * <p>Example:
+ * <pre>
+ * ShortcutManager shortcutManager = getSystemService(ShortcutManager.class);
+ *
+ * ShortcutInfo shortcut = new ShortcutInfo.Builder(this, "id1")
+ *     .setIntent(new Intent(Intent.ACTION_VIEW, Uri.parse("http://www.mysite.com/")))
+ *     .setShortLabel("Web site")
+ *     .setLongLabel("Open the web site")
+ *     .setIcon(Icon.createWithResource(context, R.drawable.icon_website))
+ *     .build();
+ *
+ * shortcutManager.setDynamicShortcuts(Arrays.asList(shortcut));
+ * </pre>
+ *
+ *
+ * <h3>Shortcut Intents</h3>
+ * Dynamic shortcuts can be published with any set of {@link Intent#addFlags Intent} flags.
+ * Typically, {@link Intent#FLAG_ACTIVITY_CLEAR_TASK} is specified, possibly along with other
+ * flags; otherwise, if the application is already running, the application is simply brought to
+ * the foreground, and the target activity may not appear.
+ *
+ * <p>The {@link ShortcutInfo.Builder#setIntents(Intent[])} method can be used instead of
+ * {@link ShortcutInfo.Builder#setIntent(Intent)} with {@link android.app.TaskStackBuilder}
+ * in order to launch an activity with other activities in the back stack.
+ * When the user selects a shortcut to load an activity with a back stack,
+ * then presses the back key, a "parent" activity will be shown instead of the user being
+ * navigated back to the launcher.
+ *
+ * <p>Manifest shortcuts can also have multiple intents to achieve the same effect.
+ * In order to associate multiple {@link Intent} objects with a shortcut, simply list multiple
+ * <code>&lt;intent&gt;</code> elements within a single <code>&lt;shortcut&gt;</code> element.
+ * The last intent specifies what the user will see when they launch a shortcut.
+ *
+ * <p>Manifest shortcuts <b>cannot</b> have custom intent flags.
+ * The first intent of a manifest shortcut will always have {@link Intent#FLAG_ACTIVITY_NEW_TASK}
+ * and {@link Intent#FLAG_ACTIVITY_CLEAR_TASK} set.
+ * This means, when the application is already running, all the existing activities will be
+ * destroyed when a manifest shortcut is launched.
+ * If this behavior is not desirable, you can use a <em>trampoline activity</em>,
+ * or an invisible activity that starts another activity in {@link Activity#onCreate},
+ * then calls {@link Activity#finish()}.
+ * The first activity should include an attribute setting
+ * of {@code android:taskAffinity=""} in the application's <code>AndroidManifest.xml</code>
+ * file, and the intent within the manifest shortcut should point at this first activity.
+ *
+ *
+ * <h3>Showing New Information in a Shortcut</h3>
+ * In order to avoid confusion, you should not use {@link #updateShortcuts(List)} to update
+ * a shortcut so that it contains conceptually different information.
+ *
+ * <p>For example, a phone application may publish the most frequently called contact as a dynamic
+ * shortcut.  Over time, this contact may change; when it does, the application should
+ * represent the changed contact with a new shortcut that contains a different ID, using either
+ * {@link #setDynamicShortcuts(List)} or {@link #addDynamicShortcuts(List)}, rather than updating
+ * the existing shortcut with {@link #updateShortcuts(List)}.
+ * This is because when the shortcut is pinned, changing
+ * it to reference a different contact will likely confuse the user.
+ *
+ * <p>On the other hand, when the
+ * contact's information has changed, such as the name or picture, the application should
+ * use {@link #updateShortcuts(List)} so that the pinned shortcut is updated too.
+ *
+ *
+ * <h3>Shortcut Display Order</h3>
+ * When the launcher displays the shortcuts that are associated with a particular launcher icon,
+ * the shortcuts should appear in the following order:
+ * <ul>
+ *   <li>First show manifest shortcuts
+ *   (if {@link ShortcutInfo#isDeclaredInManifest()} is {@code true}),
+ *   and then show dynamic shortcuts (if {@link ShortcutInfo#isDynamic()} is {@code true}).
+ *   <li>Within each category of shortcuts (manifest and dynamic), sort the shortcuts in order
+ *   of increasing rank according to {@link ShortcutInfo#getRank()}.
+ * </ul>
+ * <p>Shortcut ranks are non-negative sequential integers
+ * that determine the order in which shortcuts appear, assuming that the shortcuts are all in
+ * the same category.
+ * Ranks of existing shortcuts can be updated with
+ * {@link #updateShortcuts(List)}; you can use {@link #addDynamicShortcuts(List)} and
+ * {@link #setDynamicShortcuts(List)}, too.
+ *
+ * <p>Ranks are auto-adjusted so that they're unique for each target activity in each category
+ * (dynamic or manifest).  For example, if there are 3 dynamic shortcuts with ranks 0, 1 and 2,
+ * adding another dynamic shortcut with a rank of 1 represents a request to place this shortcut at
+ * the second position.
+ * In response, the third and fourth shortcuts move closer to the bottom of the shortcut list,
+ * with their ranks changing to 2 and 3, respectively.
+ *
+ * <h3>Rate Limiting</h3>
+ *
+ * Calls to {@link #setDynamicShortcuts(List)}, {@link #addDynamicShortcuts(List)}, and
+ * {@link #updateShortcuts(List)} may be rate-limited when called by background applications, or
+ * applications with no foreground activity or service.  When you attempt to call these methods
+ * from a background application after exceeding the rate limit, these APIs return {@code false}.
+ *
+ * <p>Applications with a foreground activity or service are not rate-limited.
+ *
+ * <p>Rate-limiting will be reset upon certain events, so that even background applications
+ * can call these APIs again until they are rate limit is reached again.
+ * These events include the following:
+ * <ul>
+ *   <li>When an application comes to the foreground.
+ *   <li>When the system locale changes.
+ *   <li>When the user performs an "inline reply" action on a notification.
+ * </ul>
+ *
+ * <p>When rate-limiting is active, {@link #isRateLimitingActive()} returns {@code true}.
+ *
+ * <h4>Resetting rate-limiting for testing</h4>
+ *
+ * If your application is rate-limited during development or testing, you can use the
+ * "Reset ShortcutManager rate-limiting" development option or the following adb command to reset
+ * it:
+ * <pre>
+ * adb shell cmd shortcut reset-throttling [ --user USER-ID ]
+ * </pre>
+ *
+ * <h3>Handling System Locale Changes</h3>
+ *
+ * Applications should update dynamic and pinned shortcuts when the system locale changes
+ * using the {@link Intent#ACTION_LOCALE_CHANGED} broadcast.
+ *
+ * <p>When the system locale changes, rate-limiting is reset, so even background applications
+ * can set dynamic shortcuts, add dynamic shortcuts, and update shortcuts until the rate limit
+ * is reached again.
+ *
  *
  * <h3>Backup and Restore</h3>
  *
- * Shortcuts will be backed up and restored across devices.  This means all information, including
- * IDs, must be meaningful on a different device.
+ * When an application has the {@code android:allowBackup="true"} attribute assignment included
+ * in its <code>AndroidManifest.xml</code> file, pinned shortcuts are
+ * backed up automatically and are restored when the user sets up a new device.
  *
- * <h3>APIs for launcher</h3>
+ * <h4>Categories of Shortcuts that are Backed Up</h4>
  *
- * Launcher applications should use {@link LauncherApps} to get shortcuts that are published from
- * applications.  Launcher applications can also pin shortcuts with
- * {@link LauncherApps#pinShortcuts(String, List, UserHandle)}.
+ * <ul>
+ *  <li>Pinned shortcuts are backed up.  Bitmap icons are not backed up by the system,
+ *  but launcher applications should back them up and restore them so that the user still sees icons
+ *  for pinned shortcuts on the launcher.  Applications can always use
+ *  {@link #updateShortcuts(List)} to re-publish icons.
  *
- * @hide
+ *  <li>Manifest shortcuts are not backed up, but when an application is re-installed on a new
+ *  device, they are re-published from the <code>AndroidManifest.xml</code> file, anyway.
+ *
+ *  <li>Dynamic shortcuts are <b>not</b> backed up.
+ * </ul>
+ *
+ * <p>Because dynamic shortcuts are not restored, it is recommended that applications check
+ * currently-published dynamic shortcuts using {@link #getDynamicShortcuts()}
+ * each time they are launched, and they should re-publish
+ * dynamic shortcuts when necessary.
+ *
+ * <pre>
+ * public class MainActivity extends Activity {
+ *     public void onCreate(Bundle savedInstanceState) {
+ *         super.onCreate(savedInstanceState);
+ *
+ *         ShortcutManager shortcutManager = getSystemService(ShortcutManager.class);
+ *
+ *         if (shortcutManager.getDynamicShortcuts().size() == 0) {
+ *             // Application restored; re-publish dynamic shortcuts.
+ *

+ *
+ * <h4>Backup/restore and shortcut IDs</h4>
+ *
+ * Because pinned shortcuts are backed up and restored on new devices, shortcut IDs should be
+ * meaningful across devices; that is, IDs should contain either stable, constant strings
+ * or server-side identifiers,
+ * rather than identifiers generated locally that might not make sense on other devices.
+ *
+ *
+ * <h3>Report Shortcut Usage and Prediction</h3>
+ *
+ * Launcher applications may be capable of predicting which shortcuts will most likely be
+ * used at a given time by examining the shortcut usage history data.
+ *
+ * <p>In order to provide launchers with such data, publisher applications should
+ * report the shortcuts that are used with {@link #reportShortcutUsed(String)}
+ * when a shortcut is selected,
+ * <b>or when an action equivalent to a shortcut is taken by the user even if it wasn't started
+ * with the shortcut</b>.
+ *
+ * <p>For example, suppose a GPS navigation application supports "navigate to work" as a shortcut.
+ * It should then report when the user selects this shortcut <b>and</b> when the user chooses
+ * to navigate to work within the application itself.
+ * This helps the launcher application
+ * learn that the user wants to navigate to work at a certain time every
+ * weekday, and it can then show this shortcut in a suggestion list at the right time.
+ *
+ * <h3>Launcher API</h3>
+ *
+ * The {@link LauncherApps} class provides APIs for launcher applications to access shortcuts.
+ *
+ *
+ * <h3>Direct Boot and Shortcuts</h3>
+ *
+ * All shortcut information is stored in credential encrypted storage, so no shortcuts can be
+ * accessed when the user is locked.

+     * (NotificationType.SIGN_IN), or to notify that a network does not have Internet access
+     * (NotificationType.NO_INTERNET). We display at most one notification per ID, so on a
+     * particular network we can display the notification type that was most recently requested.
+     * So for example if a captive portal fails to reply within a few seconds of connecting, we
+     * might first display NO_INTERNET, and then when the captive portal check completes, display
+     * SIGN_IN.
+     *
+     * @param id an identifier that uniquely identifies this notification.  This must match
+     *         between show and hide calls.  We use the NetID value but for legacy callers
+     *         we concatenate the range of types with the range of NetIDs.
+     * @param nai the network with which the notification is associated. For a SIGN_IN or
+     *         NO_INTERNET notification, this is the network we're connecting to. For a
+     *         NETWORK_SWITCH notification it's the network that we switched from. When this network
+     *         disconnects the notification is removed.
+     * @param switchToNai for a NETWORK_SWITCH notification, the network we are switching to. Null
+     *         in all other cases. Only used to determine the text of the notification.

+ * Fake for system settings.

+ * To use, ensure that the Context used by the test code returns a ContentResolver that uses this
+ * provider for the Settings authority:
+ *
+ *   class MyTestContext extends MockContext {
+ *       ...
+ *       private final MockContentResolver mContentResolver;
+ *       public MyTestContext(...) {

+ *       public ContentResolver getContentResolver() {
+ *           return mContentResolver;
+ *       }
+ *
+ * As long as the code under test is using the test Context, the actual code under test does not
+ * need to be modified, and can access Settings using the normal static methods:
+ *
+ *   Settings.Global.getInt(cr, "my_setting", 0);  // Returns 0.
+ *   Settings.Global.putInt(cr, "my_setting", 5);
+ *   Settings.Global.getInt(cr, "my_setting", 0);  // Returns 5.
+ *
+ * Note that this class cannot be used in the same process as real settings. This is because it
+ * works by passing an alternate ContentResolver to Settings operations. Unfortunately, the Settings
+ * class only fetches the content provider from the passed-in ContentResolver the first time it's
+ * used, and after that stores it in a per-process static.
+ *
+ * TODO: evaluate implementing settings change notifications. This would require:
+ *
+ * 1. Making ContentResolver#registerContentObserver non-final and overriding it in
+ *    MockContentResolver.
+ * 2. Making FakeSettingsProvider take a ContentResolver argument.
+ * 3. Calling ContentResolver#notifyChange(getUriFor(table, arg), ...) on every settings change.
