RemoteControlClient has an interface for the framework to query the playback position. This mechanism is used to detect when the estimated position drifts from the real position by having the framework regularly poll (every 15s when playing at 1x) this interface and compare against the estimation. But this mechanism: - should only be used when IRemoteControlDisplay implementation care about position display - should not be used by default because the implementation of the position query interface might involve network traffic in some remote media player implementation for instance. This CL implements an opt-in mechanism to be used by implementators of IRemoteControlDisplay, to request the anti-drift mechanism to be turned on. bug 8120740 Change-Id: I1baa3e515546ac41e0ac9c3a41bfa3147ecf3d7f
