`Unit`	`onCurrentMediaItemChanged(@NonNull player: SessionPlayer, @NonNull item: MediaItem)` Called when the player's current media item has changed. Generally called after a new media item is set through `setPlaylist` or `setMediaItem`, or after skipping to a different item in a given playlist.
`Unit`	`onPlaybackCompleted(@NonNull player: SessionPlayer)` Called when the player finished playing. Playback state would be also set `PLAYER_STATE_PAUSED` with it. This will be called only when the repeat mode is set to `REPEAT_MODE_NONE`.

`Unit`	`onPlayerStateChanged(@NonNull player: SessionPlayer, playerState: Int)` Called when the state of the player has changed.
`Unit`	`onPlaylistChanged(@NonNull player: SessionPlayer, @Nullable list: MutableList<MediaItem!>?, @Nullable metadata: MediaMetadata?)` Called when a playlist is changed. It's also called after `setPlaylist` or `setMediaItem`.
`Unit`	`onPlaylistMetadataChanged(@NonNull player: SessionPlayer, @Nullable metadata: MediaMetadata?)` Called when a playlist metadata is changed.
`Unit`	`onRepeatModeChanged(@NonNull player: SessionPlayer, repeatMode: Int)` Called when the repeat mode is changed. `SessionPlayer#getPreviousMediaItemIndex()` and `SessionPlayer#getNextMediaItemIndex()` values can be outdated when this callback is called if the current media item is the first or last item in the playlist.
`Unit`	`onSeekCompleted(@NonNull player: SessionPlayer, position: Long)` Called when `seekTo(long)` is completed.
`Unit`	`onShuffleModeChanged(@NonNull player: SessionPlayer, shuffleMode: Int)` Called when the shuffle mode is changed. `SessionPlayer#getPreviousMediaItemIndex()` and `SessionPlayer#getNextMediaItemIndex()` values can be outdated when this callback is called if the current media item is the first or last item in the playlist.
`Unit`	`onSubtitleData(@NonNull player: SessionPlayer, @NonNull item: MediaItem, @NonNull track: SessionPlayer.TrackInfo, @NonNull data: SubtitleData)` Called when the player's subtitle track has new subtitle data available.
`Unit`	`onTrackDeselected(@NonNull player: SessionPlayer, @NonNull trackInfo: SessionPlayer.TrackInfo)` Called when a track is deselected. This callback will generally be called only after calling `deselectTrack(TrackInfo)`.
`Unit`	`onTrackSelected(@NonNull player: SessionPlayer, @NonNull trackInfo: SessionPlayer.TrackInfo)` Called when a track is selected.
