```
public interface AnalyticsListener
```
A listener for analytics events.
All events are recorded with an AnalyticsListener.EventTime specifying the elapsed real time and media time at the time of the event.
All methods have no-op default implementations to allow selective overrides.
Listeners can choose to implement individual events (e.g. onIsPlayingChanged(EventTime, boolean)) or onEvents(Player, Events), which is called after one or more events occurred together.

    This method being called does not indicate that playback has failed, or that it will fail. The player may be able to recover from the error. Hence applications should not implement this method to display a user visible error or initiate an application level retry. Player.Listener.onPlayerError(com.google.android.exoplayer2.PlaybackException) is the appropriate place to implement such behavior. This method is called to provide the application with an opportunity to log the error if it wishes to do so.
    
    Parameters:
    
    eventTime - The event time.
    
    loadEventInfo - The LoadEventInfo defining the load event.
    
    mediaLoadData - The MediaLoadData defining the data being loaded.
    
    error - The load error.
    
    wasCanceled - Whether the load was canceled as a result of the error.

    Listeners should prefer this method over individual callbacks in the following cases:
    
    They intend to trigger the same logic for multiple events (e.g. when updating a UI for both onPlaybackStateChanged(EventTime, int) and onPlayWhenReadyChanged(EventTime, boolean, int)).
    They need access to the Player object to trigger further events (e.g. to call Player.seekTo(long) after a onMediaItemTransition(EventTime, MediaItem, int)).
    They intend to use multiple state values together or in combination with Player getter methods. For example using Player.getCurrentMediaItemIndex() with the timeline provided in onTimelineChanged(EventTime, int) is only safe from within this method.
    They are interested in events that logically happened together (e.g onPlaybackStateChanged(EventTime, int) to Player.STATE_BUFFERING because of onMediaItemTransition(EventTime, MediaItem, int)).
    Parameters:
    
    player - The Player.
    
    events - The AnalyticsListener.Events that occurred in this iteration.
