Please refer to ACTION_END_SESSION for more information about the semantics of this request.

Parameters
extras Bundle: A bundle of extra arguments to be added to the ACTION_END_SESSION intent, or null if none.
callback RemotePlaybackClient.SessionActionCallback: A callback to invoke when the request has been processed, or null if none.
Throws
IllegalStateException if there is no current session.
UnsupportedOperationException if the route does not support session management.

enqueue
