-/**
- * MediaPlayer2 class can be used to control playback of audio/video files and streams.
- *
- * <p>
- * This API is not generally intended for third party application developers.
- * Use the <a href="{@docRoot}jetpack/androidx.html">AndroidX</a>
- * <a href="{@docRoot}reference/androidx/media2/package-summary.html">Media2 Library</a>
- * for consistent behavior across all devices.
- *
- * <p>Topics covered here are:
- * <ol>
- * <li><a href="#PlayerStates">Player states</a>
- * <li><a href="#InvalidStates">Invalid method calls</a>
- * <li><a href="#Permissions">Permissions</a>
- * <li><a href="#Callbacks">Callbacks</a>
- * </ol>
- *
- *
- * <h3 id="PlayerStates">Player states</h3>
- *
- * <p>The playback control of audio/video files is managed as a state machine.</p>
- * <p><div style="text-align:center;"><img src="../../../images/mediaplayer2_state_diagram.png"
- *         alt="MediaPlayer2 State diagram"
- *         border="0" /></div></p>
- * <p>The MediaPlayer2 object has five states:</p>
- * <ol>
- *     <li><p>{@link #PLAYER_STATE_IDLE}: MediaPlayer2 is in the <strong>Idle</strong>
- *         state after it's created, or after calling {@link #reset()}.</p>
- *
- *         <p>While in this state, you should call
- *         {@link #setDataSource setDataSource}. It is a good
- *         programming practice to register an {@link EventCallback#onCallCompleted onCallCompleted}
- *         <a href="#Callbacks">callback</a> and watch for {@link #CALL_STATUS_BAD_VALUE} and
- *         {@link #CALL_STATUS_ERROR_IO}, which might be caused by <code>setDataSource</code>.
- *         </p>
- *
- *         <p>Calling {@link #prepare()} transfers a MediaPlayer2 object to
- *         the <strong>Prepared</strong> state. Note
- *         that {@link #prepare()} is asynchronous. When the preparation completes,
- *         if you register an {@link EventCallback#onInfo onInfo} <a href="#Callbacks">callback</a>,
- *         the player executes the callback
- *         with {@link #MEDIA_INFO_PREPARED} and transitions to the
- *         <strong>Prepared</strong> state.</p>
- *         </li>
- *
- *     <li>{@link #PLAYER_STATE_PREPARED}: A MediaPlayer object must be in the
- *         <strong>Prepared</strong> state before playback can be started for the first time.
- *         While in this state, you can set player properties
- *         such as audio/sound volume and looping by invoking the corresponding set methods.
- *         Calling {@link #play()} transfers a MediaPlayer2 object to
- *         the <strong>Playing</strong> state.
- *      </li>
- *
- *     <li>{@link #PLAYER_STATE_PLAYING}:
- *         <p>The player plays the data source while in this state.
- *         If you register an {@link EventCallback#onInfo onInfo} <a href="#Callbacks">callback</a>,
- *         the player regularly executes the callback with
- *         {@link #MEDIA_INFO_BUFFERING_UPDATE}.
- *         This allows applications to keep track of the buffering status
- *         while streaming audio/video.</p>
- *
- *         <p> When the playback reaches the end of stream, the behavior depends on whether or
- *         not you've enabled looping by calling {@link #loopCurrent}:</p>
- *         <ul>
- *         <li>If the looping mode was set to <code>false</code>, the player will transfer
- *         to the <strong>Paused</strong> state. If you registered an {@link EventCallback#onInfo
- *         onInfo} <a href="#Callbacks">callback</a>
- *         the player calls the callback with {@link #MEDIA_INFO_DATA_SOURCE_END} and enters
- *         the <strong>Paused</strong> state.
- *         </li>
- *         <li>If the looping mode was set to <code>true</code>,
- *         the MediaPlayer2 object remains in the <strong>Playing</strong> state and replays its
- *         data source from the beginning.</li>
- *         </ul>
- *         </li>
- *
- *     <li>{@link #PLAYER_STATE_PAUSED}: Audio/video playback pauses while in this state.
- *         Call {@link #play()} to resume playback from the position where it paused.</li>
- *
- *     <li>{@link #PLAYER_STATE_ERROR}: <p>In general, playback might fail due to various
- *          reasons such as unsupported audio/video format, poorly interleaved
- *          audio/video, resolution too high, streaming timeout, and others.
- *          In addition, due to programming errors, a playback
- *          control operation might be performed from an <a href="#InvalidStates">invalid state</a>.
- *          In these cases the player transitions to the <strong>Error</strong> state.</p>
- *
- *          <p>If you register an {@link EventCallback#onError onError}}
- *          <a href="#Callbacks">callback</a>,
- *          the callback will be performed when entering the state. When programming errors happen,
- *          such as calling {@link #prepare()} and
- *          {@link #setDataSource} methods
- *          from an <a href="#InvalidStates">invalid state</a>, the callback is called with
- *          {@link #CALL_STATUS_INVALID_OPERATION}. The MediaPlayer2 object enters the
- *          <strong>Error</strong> state whether or not a callback exists. </p>
- *
- *          <p>To recover from an error and reuse a MediaPlayer2 object that is in the <strong>
- *          Error</strong> state,
- *          call {@link #reset()}. The object will return to the <strong>Idle</strong>
- *          state and all state information will be lost.</p>
- *          </li>
- * </ol>
- *
- * <p>You should follow these best practices when coding an app that uses MediaPlayer2:</p>
- *
- * <ul>
- *
- * <li>Use <a href="#Callbacks">callbacks</a> to respond to state changes and errors.</li>
- *
- * <li>When  a MediaPlayer2 object is no longer being used, call {@link #close()} as soon as
- * possible to release the resources used by the internal player engine associated with the
- * MediaPlayer2. Failure to call {@link #close()} may cause subsequent instances of
- * MediaPlayer2 objects to fallback to software implementations or fail altogether.
- * You cannot use MediaPlayer2
- * after you call {@link #close()}. There is no way to bring it back to any other state.</li>
- *
- * <li>The current playback position can be retrieved with a call to
- * {@link #getCurrentPosition()},
- * which is helpful for applications such as a Music player that need to keep track of the playback
- * progress.</li>
- *
- * <li>The playback position can be adjusted with a call to {@link #seekTo}. Although the
- * asynchronous {@link #seekTo} call returns right away, the actual seek operation may take a
- * while to finish, especially for audio/video being streamed. If you register an
- * {@link EventCallback#onCallCompleted onCallCompleted} <a href="#Callbacks">callback</a>,
- * the callback is
- * called When the seek operation completes with {@link #CALL_COMPLETED_SEEK_TO}.</li>
- *
- * <li>You can call {@link #seekTo} from the <strong>Paused</strong> state.
- * In this case, if you are playing a video stream and
- * the requested position is valid  one video frame is displayed.</li>
- *
- * </ul>
- *
- * <h3 id="InvalidStates">Invalid method calls</h3>
- *
- * <p>The only methods you safely call from the <strong>Error</strong> state are
- * {@link #close},
- * {@link #reset},
- * {@link #notifyWhenCommandLabelReached},
- * {@link #clearPendingCommands},
- * {@link #registerEventCallback},
- * {@link #unregisterEventCallback}
- * and {@link #getState}.
- * Any other methods might throw an exception, return meaningless data, or invoke a
- * {@link EventCallback#onCallCompleted onCallCompleted} with an error code.</p>
- *
- * <p>Most methods can be called from any non-Error state. They will either perform their work or
- * silently have no effect. The following table lists the methods that will invoke a
- * {@link EventCallback#onCallCompleted onCallCompleted} with an error code
- * or throw an exception when they are called from the associated invalid states.</p>
- *
- * <table border="0" cellspacing="0" cellpadding="0">
- * <tr><th>Method Name</th>
- * <th>Invalid States</th></tr>
- *
- * <tr><td>setDataSource</td> <td>{Prepared, Paused, Playing}</td></tr>
- * <tr><td>prepare</td> <td>{Prepared, Paused, Playing}</td></tr>
- * <tr><td>play</td> <td>{Idle}</td></tr>
- * <tr><td>pause</td> <td>{Idle}</td></tr>
- * <tr><td>seekTo</td> <td>{Idle}</td></tr>
- * <tr><td>getCurrentPosition</td> <td>{Idle}</td></tr>
- * <tr><td>getDuration</td> <td>{Idle}</td></tr>
- * <tr><td>getBufferedPosition</td> <td>{Idle}</td></tr>
- * <tr><td>getTrackInfo</td> <td>{Idle}</td></tr>
- * <tr><td>getSelectedTrack</td> <td>{Idle}</td></tr>
- * <tr><td>selectTrack</td> <td>{Idle}</td></tr>
- * <tr><td>deselectTrack</td> <td>{Idle}</td></tr>
- * </table>
- *
- * <h3 id="Permissions">Permissions</h3>
- * <p>This class requires the {@link android.Manifest.permission#INTERNET} permission
- * when used with network-based content.
- *
- * <h3 id="Callbacks">Callbacks</h3>
- * <p>Many errors do not result in a transition to the  <strong>Error</strong> state.
- * It is good programming practice to register callback listeners using
- * {@link #registerEventCallback}.
- * You can receive a callback at any time and from any state.</p>
- *
- * <p>If it's important for your app to respond to state changes (for instance, to update the
- * controls on a transport UI), you should register an
- * {@link EventCallback#onCallCompleted onCallCompleted} and
- * detect state change commands by testing the <code>what</code> parameter for a callback from one
- * of the state transition methods: {@link #CALL_COMPLETED_PREPARE}, {@link #CALL_COMPLETED_PLAY},
- * and {@link #CALL_COMPLETED_PAUSE}.
- * Then check the <code>status</code> parameter. The value {@link #CALL_STATUS_NO_ERROR} indicates a
- * successful transition. Any other value will be an error. Call {@link #getState()} to
- * determine the current state. </p>

-/**
- * A simple in-process event bus.  It is simple because we can make assumptions about the state of
- * SystemUI and Recent's lifecycle.
- *
- * <p>
- * Currently, there is a single EventBus that handles {@link EventBus.Event}s for each subscriber
- * on the main application thread.  Publishers can send() events to synchronously call subscribers
- * of that event, or post() events to be processed in the next run of the {@link Looper}.
- *
- * <p>
- * Subscribers must be registered with a particular EventBus before they will receive events, and
- * handler methods must match a specific signature.
- *
- * <p>
- * Event method signature:<ul>
- * <li>Methods must be public final
- * <li>Methods must return void
- * <li>Methods must be called "onBusEvent"
- * <li>Methods must take one parameter, of class type deriving from {@link EventBus.Event}
- * </ul>
- *
- * </p>
- * Each subscriber can be registered with a given priority (default 1), and events will be dispatch
- * in decreasing order of priority.  For subscribers with the same priority, events will be
- * dispatched by latest registration time to earliest.
- *
- * <p>
- * Caveats:<ul>
- * <li>The EventBus keeps a {@link WeakReference} to the publisher to prevent memory leaks, so
- * there must be another strong reference to the publisher for it to not get garbage-collected and
- * continue receiving events.
- * <li>Because the event handlers are called back using reflection, the EventBus is not intended
- * for use in tight, performance criticial loops.  For most user input/system callback events, this
- * is generally of low enough frequency to use the EventBus.
- * <li>Because the event handlers are called back using reflection, there will often be no
- * references to them from actual code.  The proguard configuration will be need to be updated to
- * keep these extra methods:
- *
- * -keepclassmembers class ** {
- * public void onBusEvent(**);
- * public void onInterprocessBusEvent(**);
- * }
- * -keepclassmembers class ** extends **.EventBus$InterprocessEvent {
- * public <init>(android.os.Bundle);
- * }
- *
- * <li>Subscriber registration can be expensive depending on the subscriber's {@link Class}.  This
- * is only done once per class type, but if possible, it is best to pre-register an instance of
- * that class beforehand or when idle.
- * <li>Each event should be sent once.  Events may hold internal information about the current
- * dispatch, or may be queued to be dispatched on another thread (if posted from a non-main thread),
- * so it may be unsafe to edit, change, or re-send the event again.
- * <li>Events should follow a pattern of public-final POD (plain old data) objects, where they are
- * initialized by the constructor and read by each subscriber of that event.  Subscribers should
- * never alter events as they are processed, and this enforces that pattern.
- * </ul>
- *
- * <p>
- * Future optimizations:
- * <li>throw exception/log when a subscriber loses the reference
- * <li>trace cost per registration & invocation
- * <li>trace cross-process invocation
- * <li>register(subscriber, Class&lt;?&gt;...) -- pass in exact class types you want registered
- * <li>setSubscriberEventHandlerPriority(subscriber, Class<Event>, priority)
- * <li>allow subscribers to implement interface, ie. EventBus.Subscriber, which lets then test a
- * message before invocation (ie. check if task id == this task id)
- * <li>add postOnce() which automatically debounces
- * <li>add postDelayed() which delays / postDelayedOnce() which delays and bounces
- * <li>consolidate register() and registerInterprocess()
- * <li>sendForResult&lt;ReturnType&gt;(Event) to send and get a result, but who will send the
- * result?
- * </p>

+ * ProtoLog API - exposes static logging methods. Usage of this API is similar
+ * to {@code android.utils.Log} class. Instead of plain text log messages each call consists of
+ * a messageString, which is a format string for the log message (has to be a string literal or
+ * a concatenation of string literals) and a vararg array of parameters for the formatter.
+ *
+ * The syntax for the message string is a subset of {@code java.util.Formatter} syntax.
+ * Supported conversions:
+ * %b - boolean
+ * %d, %o and %x - integral type (Short, Integer or Long)
+ * %f, %e and %g - floating point type (Float or Double)
+ * %s - string
+ * %% - a literal percent character
+ * The width and precision modifiers are supported, argument_index and flags are not.
+ *
+ * Methods in this class are stubs, that are replaced by optimised versions by the ProtoLogTool
+ * during build.

+ * This test makes sure app installs with fs-verity signature, and on-access verification works.
+ *
+ * <p>When an app is installed, all or none of the files should have their corresponding .fsv_sig
+ * signature file. Otherwise, install will fail.
+ *
+ * <p>Once installed, file protected by fs-verity is verified by kernel every time a block is loaded
+ * from disk to memory. The file is immutable by design, enforced by filesystem.
+ *
+ * <p>In order to make sure a block of the file is readable only if the underlying block on disk
+ * stay intact, the test needs to bypass the filesystem and tampers with the corresponding physical
+ * address against the block device.
+ *
+ * <p>Requirements to run this test:
+ * <ul>
+ *   <li>Device is rootable</li>
+ *   <li>The filesystem supports fs-verity</li>
+ *   <li>The feature flag is enabled</li>

+The test tries to install subsets of base.{apk,dm}, split.{apk,dm} and their
+corresponding .fsv_sig files (generated by build rule). If installed, the
+tests also tries to tamper with the file at absolute disk offset to verify
+if fs-verity is effective.

- * Builds and runs UI transitions capturing test artifacts.

- * User can compose a transition from simpler steps, specifying setup and teardown steps. During
- * a transition, Layers trace, WindowManager trace, screen recordings and window animation frame
- * stats can be captured.
- *
- * <pre>
- * Transition builder options:
- *  {@link TransitionBuilder#run(Runnable)} run transition under test. Monitors will be started
- *  before the transition and stopped after the transition is completed.
- *  {@link TransitionBuilder#repeat(int)} repeat transitions under test multiple times recording
- *  result for each run.
- *  {@link TransitionBuilder#withTag(String)} specify a string identifier used to prefix logs and
- *  artifacts generated.
- *  {@link TransitionBuilder#runBeforeAll(Runnable)} run setup transitions once before all other
- *  transition are run to set up an initial state on device.
- *  {@link TransitionBuilder#runBefore(Runnable)} run setup transitions before each test transition
- *  run.
- *  {@link TransitionBuilder#runAfter(Runnable)} run teardown transitions after each test
- *  transition.
- *  {@link TransitionBuilder#runAfter(Runnable)} run teardown transitions once after all
- *  other transition  are run.
- *  {@link TransitionBuilder#includeJankyRuns()} disables {@link WindowAnimationFrameStatsMonitor}
- *  to monitor janky frames. If janky frames are detected, then the test run is skipped. This
- *  monitor is enabled by default.
- *  {@link TransitionBuilder#skipLayersTrace()} disables {@link LayersTraceMonitor} used to
- *  capture Layers trace during a transition. This monitor is enabled by default.
- *  {@link TransitionBuilder#skipWindowManagerTrace()} disables {@link WindowManagerTraceMonitor}
- *  used to capture WindowManager trace during a transition. This monitor is enabled by
- *  default.
- *  {@link TransitionBuilder#recordAllRuns()} records the screen contents and saves it to a file.
- *  All the runs including setup and teardown transitions are included in the recording. This
- *  monitor is used for debugging purposes.
- *  {@link TransitionBuilder#recordEachRun()} records the screen contents during test transitions
- *  and saves it to a file for each run. This monitor is used for debugging purposes.
- *
- * Example transition to capture WindowManager and Layers trace when opening a test app:
- * {@code
- * TransitionRunner.newBuilder()
- *      .withTag("OpenTestAppFast")
- *      .runBeforeAll(UiAutomationLib::wakeUp)
- *      .runBeforeAll(UiAutomationLib::UnlockDevice)
- *      .runBeforeAll(UiAutomationLib::openTestApp)
- *      .runBefore(UiAutomationLib::closeTestApp)
- *      .run(UiAutomationLib::openTestApp)
- *      .runAfterAll(UiAutomationLib::closeTestApp)
- *      .repeat(5)
- *      .build()
- *      .run();
