* MediaPlayer2 class can be used to control playback of audio/video files and streams.

* Use the <a href="{@docRoot}jetpack/androidx.html">AndroidX</a>
|
||
* <a href="{@docRoot}reference/androidx/media2/package-summary.html">Media2 Library</a>

* <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>
|

|

|

|

||
*
|
||
* <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>
