public ControllerCallback()

Methods

public void onConnected(MediaController controller, SessionCommandGroup allowedCommands)

Called when the controller is successfully connected to the session. The controller becomes available afterwards.

Parameters:

controller: the controller for this event
allowedCommands: commands that's allowed by the session

public void onDisconnected(MediaController controller)

Called when the session refuses the controller or the controller is disconnected from the session. The controller becomes unavailable afterwards and the callback wouldn't be called.

It will be also called after the MediaController.close(), so you can put clean up code here. You don't need to call MediaController.close() after this.

Parameters:

controller: the controller for this event

public int onSetCustomLayout(MediaController controller, java.util.List<MediaSession.CommandButton> layout)

Called when the session set the custom layout through the MediaSession.setCustomLayout(MediaSession.ControllerInfo, List).

Can be called before MediaController.ControllerCallback.onConnected(MediaController, SessionCommandGroup) is called.

Default implementation returns BaseResult.RESULT_ERROR_NOT_SUPPORTED.

Parameters:

controller: the controller for this event
layout:

public void onPlaybackInfoChanged(MediaController controller, MediaController.PlaybackInfo info)

Called when the session has changed anything related with the MediaController.PlaybackInfo.

Interoperability: When connected to android.support.v4.media.session.MediaSessionCompat, this may be called when the session changes playback info by calling setPlaybackToLocal or setPlaybackToRemote}. Specifically:

Prior to API 21, this will always be called whenever any of those two methods is called.
From API 21 to 22, this is called only when the playback type is changed from local to remote (i.e. not from remote to local).
From API 23, this is called only when the playback type is changed.

Parameters:

controller: the controller for this event
info: new playback info

public void onAllowedCommandsChanged(MediaController controller, SessionCommandGroup commands)

Called when the allowed commands are changed by session.

Parameters:

controller: the controller for this event
commands: newly allowed commands

public SessionResult onCustomCommand(MediaController controller, SessionCommand command, Bundle args)

Called when the session sent a custom command. Returns a SessionResult for session to get notification back. If the null is returned, BaseResult.RESULT_ERROR_UNKNOWN will be returned.

Default implementation returns BaseResult.RESULT_ERROR_NOT_SUPPORTED.

Parameters:

controller: the controller for this event
command:
args:

Returns:

result of handling custom command

public void onPlayerStateChanged(MediaController controller, int state)

Called when the player state is changed.

Parameters:

controller: the controller for this event
state: the new player state

public void onPlaybackSpeedChanged(MediaController controller, float speed)

Called when playback speed is changed.

Parameters:

controller: the controller for this event
speed: speed

public void onBufferingStateChanged(MediaController controller, MediaItem item, int state)

Called to report buffering events for a media item.

Use MediaController.getBufferedPosition() for current buffering position.

Parameters:

controller: the controller for this event
item: the media item for which buffering is happening
state: the new buffering state

public void onSeekCompleted(MediaController controller, long position)

Called to indicate that seeking is completed.

Parameters:

controller: the controller for this event
position: the previous seeking request

public void onCurrentMediaItemChanged(MediaController controller, MediaItem item)

Called when the current item is changed. It's also called after MediaController.setPlaylist(List, MediaMetadata) or MediaController.setMediaItem(String). Also called when MediaItem.setMetadata(MediaMetadata) is called on the current media item.

When it's called, you should invalidate previous playback information and wait for later callbacks. Also, current, previous, and next media item indices may need to be updated.

Parameters:

controller: the controller for this event
item: new current media item

public void onPlaylistChanged(MediaController controller, java.util.List<MediaItem> list, MediaMetadata metadata)

Called when a playlist is changed. It's also called after MediaController.setPlaylist(List, MediaMetadata) or MediaController.setMediaItem(String). Also called when MediaItem.setMetadata(MediaMetadata) is called on a media item that is contained in the current playlist.

When it's called, current, previous, and next media item indices may need to be updated.

Parameters:

controller: the controller for this event
list: new playlist
metadata: new metadata

public void onPlaylistMetadataChanged(MediaController controller, MediaMetadata metadata)
