Interface TrackPositionListener

public interface TrackPositionListener

The listener interface for receiving updates when there are significant changes to the movement through a track on a player (for example, to send time code that represents the progress of playing the track).

Classes that are interested in being informed when unexpected movement or changes in playback state occur on a player can implement this interface, and then pass the implementing instance to TimeFinder.addTrackPositionListener(int, TrackPositionListener). Then, whenever a player loads a new track (or the set of available metadata changes, so we know more or less about tracks in any loaded player), movementChanged(TrackPositionUpdate) will be called, with the currently available position and movement information about the track being played by the player.
