This class was deprecated
in API level 21.
Use MediaSession
instead.
RemoteControlClient enables exposing information meant to be consumed by remote controls capable of displaying metadata, artwork and media transport control buttons.
A remote control client object is associated with a media button event receiver. This
event receiver must have been previously registered with
AudioManager.registerMediaButtonEventReceiver(ComponentName)
before the
RemoteControlClient can be registered through
AudioManager.registerRemoteControlClient(RemoteControlClient)
.
Here is an example of creating a RemoteControlClient instance after registering a media button event receiver:
ComponentName myEventReceiver = new ComponentName(getPackageName(), MyRemoteControlEventReceiver.class.getName()); AudioManager myAudioManager = (AudioManager) getSystemService(Context.AUDIO_SERVICE); myAudioManager.registerMediaButtonEventReceiver(myEventReceiver); // build the PendingIntent for the remote control client Intent mediaButtonIntent = new Intent(Intent.ACTION_MEDIA_BUTTON); mediaButtonIntent.setComponent(myEventReceiver); PendingIntent mediaPendingIntent = PendingIntent.getBroadcast(getApplicationContext(), 0, mediaButtonIntent, PendingIntent.FLAG_MUTABLE_UNAUDITED); // create and register the remote control client RemoteControlClient myRemoteControlClient = new RemoteControlClient(mediaPendingIntent); myAudioManager.registerRemoteControlClient(myRemoteControlClient);

by remote controls.
This intent needs to have been constructed with the Intent.ACTION_MEDIA_BUTTON
action, and have a component that will handle the intent (set with
Intent.setComponent(ComponentName) ) registered with
AudioManager.registerMediaButtonEventReceiver(ComponentName)
before this new RemoteControlClient can itself be registered with

is PLAYSTATE_BUFFERING and nothing had played yet). |
playbackSpeed |
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 PLAYSTATE_ERROR ). |
