fun onEvents(player: Player!, events: AnalyticsListener.Events!): Unit

Called after one or more events occurred.

State changes and events that happen within one Looper message queue iteration are reported together and only after all individual callbacks were triggered.

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 and onPlayWhenReadyChanged).
• They need access to the Player object to trigger further events (e.g. to call seekTo after a onMediaItemTransition).
• They intend to use multiple state values together or in combination with Player getter methods. For example using getCurrentMediaItemIndex with the timeline provided in onTimelineChanged is only safe from within this method.
• They are interested in events that logically happened together (e.g onPlaybackStateChanged to STATE_BUFFERING because of onMediaItemTransition).
