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

| * <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 you create it using |
| * {@link #create()}, or after calling {@link #reset()}.</p> |
| * |
| * <p>While in this state, you should call |
| * {@link #setDataSource(DataSourceDesc2) 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(boolean) 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() prepare} and |
| * {@link #setDataSource(DataSourceDesc) 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() 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() close} as soon as |
| * possible to release the resources used by the internal player engine associated with the |
| * MediaPlayer2. Failure to call {@link #close() 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() 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() 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 seekTo}. Although the |
| * asynchronous {@link #seekTo 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 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() close}, |
| * {@link #reset() reset}, |
| * {@link #notifyWhenCommandLabelReached notifyWhenCommandLabelReached}, |
| * {@link #clearPendingCommands() clearPendingCommands}, |
| * {@link #setEventCallback setEventCallback}, |
| * {@link #clearEventCallback() clearEventCallback} |
| * and {@link #getState() 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 #setEventCallback(Executor, EventCallback) setEventCallback} and |
| * {@link #setDrmEventCallback(Executor, DrmEventCallback) setDrmEventCallback}). |
| * 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> |
