Public methods

onClientChange

Added in API level 19

public abstract void onClientChange (boolean clearing)

Called whenever all information, previously received through the other methods of the listener, is no longer valid and is about to be refreshed. This is typically called whenever a new RemoteControlClient has been selected by the system to have its media information published.

Parameters
clearing	boolean: true if there is no selected RemoteControlClient and no information is available.

onClientMetadataUpdate

Added in API level 19

public abstract void onClientMetadataUpdate (RemoteController.MetadataEditor metadataEditor)

Called whenever new metadata is available. See the MediaMetadataEditor#putLong(int, long), MediaMetadataEditor#putString(int, String), MediaMetadataEditor#putBitmap(int, Bitmap), and MediaMetadataEditor#putObject(int, Object) methods for the various keys that can be queried.

Parameters
metadataEditor	RemoteController.MetadataEditor: the container of the new metadata.

onClientPlaybackStateUpdate

Added in API level 19

public abstract void onClientPlaybackStateUpdate (int state, 
                long stateChangeTimeMs, 
                long currentPosMs, 
                float speed)

Called whenever the playback state has changed, and playback position and speed are known.

Parameters
state	int: one of the playback states authorized in RemoteControlClient#setPlaybackState(int).
stateChangeTimeMs	long: the system time at which the state change was reported, expressed in ms. Based on SystemClock.elapsedRealtime().
currentPosMs	long: a positive value for the current media playback position expressed in ms, a negative value if the position is temporarily unknown.
speed	float: a value expressed as a ratio of 1x playback: 1.0f is normal playback, 2.0f is 2x, 0.5f is half-speed, -2.0f is rewind at 2x speed. 0.0f means nothing is playing (e.g. when state is RemoteControlClient#PLAYSTATE_ERROR).

onClientPlaybackStateUpdate

Added in API level 19

public abstract void onClientPlaybackStateUpdate (int state)

Called whenever the playback state has changed. It is called when no information is known about the playback progress in the media and the playback speed.

Parameters
state	int: one of the playback states authorized in RemoteControlClient#setPlaybackState(int).

onClientTransportControlUpdate

Added in API level 19

public abstract void onClientTransportControlUpdate (int transportControlFlags)

Called whenever the transport control flags have changed.

Parameters
transportControlFlags	int: one of the flags authorized in RemoteControlClient#setTransportControlFlags(int).
