Player states

* *

The playback control of audio/video files is managed as a state machine.

*

MediaPlayer2 State diagram

*

The MediaPlayer2 object has five states:

*
    *
  1. {@link #PLAYER_STATE_IDLE}: MediaPlayer2 is in the Idle * state after you create it using * {@link #create(Context)}, or after calling {@link #reset()}.

    * *

    While in this state, you should call * {@link #setDataSource(DataSourceDesc2) setDataSource()}. It is a good * programming practice to register an {@link EventCallback#onCallCompleted onCallCompleted} * callback and watch for {@link #CALL_STATUS_BAD_VALUE} and * {@link #CALL_STATUS_ERROR_IO}, which might be caused by setDataSource. *

    * *

    Calling {@link #prepare()} transfers a MediaPlayer2 object to * the Prepared state. Note * that {@link #prepare()} is asynchronous. When the preparation completes, * If you register a {@link EventCallback#onInfo} callback * the player executes the callback * with {@link #MEDIA_INFO_PREPARED} before transitioning to the * Prepared state.

    *
  2. * *
  3. {@link #PLAYER_STATE_PREPARED}: A MediaPlayer object must be in the * Prepared 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 Playing state. *
  4. * *
  5. {@link #PLAYER_STATE_PLAYING}: *

    The player plays the data source while in this state. * If you register an {@link EventCallback#onInfo} callback * 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.

    * *

    When the playback reaches the end of stream, the behavior depends on whether or * not you've enabled looping by calling {@link #loopCurrent(boolean)}:

    * *
  6. * *
  7. {@link #PLAYER_STATE_PAUSED}: Audio/video playback pauses while in this state. * Call {@link #play()} to resume playback from the position where it paused.
  8. * *
  9. {@link #PLAYER_STATE_ERROR}:

    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 invalid state. * In these cases the player transitions to the Error state.

    * *

    If you register an {@link EventCallback#onError}} callback * the callback will be performed when entering the state. When programming errors happen, * such as calling {@link #prepare()} and {@link #setDataSource(DataSourceDesc2)} methods * from an invalid state, The callback is called with * {@link #CALL_STATUS_INVALID_OPERATION} . The MediaPlayer2 object enters the * Error whether or not a callback exists.

    * *

    To recover from an error and reuse a MediaPlayer2 object that is in the * Error state, * call {@link #reset()}. The object will return to the Idle * state and all state information will be lost.

    *
  10. *
* *

You should follow these best practices when coding an app that uses MediaPlayer2:

* * * *

Invalid method calls

* *

The only methods you safely call from the Error state are {@link #close()}, * {@link #reset()}, {@link #notifyWhenCommandLabelReached}, {@link #clearPendingCommands()}, * {@link #setEventCallback}, {@link #clearEventCallback()} and {@link #getState()}. * Any other methods might throw an exception, return meaningless data, or invoke a * {@link EventCallback#onCallCompleted} with an error code.

* *

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} with an error code or throw an exception when they are * called from the associated invalid states.

* * * * * * * * * * * * * * * * * *
Method NameInvalid States
setDataSource {Prepared, Paused, Playing}
prepare {Prepared, Paused, Playing}
play {Idle}
pause {Idle}
seekTo {Idle}
getCurrentPosition {Idle}
getDuration {Idle}
getBufferedPosition {Idle}
getTrackInfo {Idle}
getSelectedTrack {Idle}
selectTrack {Idle}
deselectTrack {Idle}
* *

Permissions

*

This class requires the {@link android.Manifest.permission#INTERNET} permission * when used with network-based content. * *

Callbacks

*

Many errors do not result in a transition to the Error state. * It is good programming practice to register callback listeners using * {@link #setEventCallback(Executor, EventCallback)} and * {@link #setDrmEventCallback(Executor, DrmEventCallback)}). * You can receive a callback at any time and from any state.

* *

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} and * detect state change commands by testing the what 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 status 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. * (You can also register a {@link MediaPlayerConnector.PlayerEventCallback#onPlayerStateChanged} * callback but this method does not distinguish between the Idle and * Prepared states.)

* *

You can also register a {@link MediaPlayerConnector.PlayerEventCallback#onPlayerStateChanged} * callback. Call {@link #getState()} from your code to determine the state.

* *

In order for callbacks to work, your app must create * MediaPlayer2 objects on a thread that has its own running Looper. This can be done on the main UI * thread, which has a Looper.
