 ### Playback errors ###
 
 Errors that cause playback to fail can be received by implementing
-`onPlayerError(ExoPlaybackException error)` in a registered
+`onPlayerError(PlaybackException error)` in a registered
 `Player.Listener`. When a failure occurs, this method will be called
 immediately before the playback state transitions to `Player.STATE_IDLE`.
 Failed or stopped playbacks can be retried by calling `ExoPlayer.retry`.
 
-[`ExoPlaybackException`][] has a `type` field, as well as corresponding getter
-methods that return cause exceptions providing more information about the
-failure. The example below shows how to detect when a playback has failed due to
-a HTTP networking issue.
+Note that some [`Player`][] implementations pass instances of subclasses of
+`PlaybackException` to provide additional information about the failure. For
+example, [`ExoPlayer`][] passes [`ExoPlaybackException`][] which has `type`,
+`rendererIndex` and other ExoPlayer-specific fields.
