Inherited functions

From class MediaController ListenableFuture<SessionResult!> addPlaylistItem(@IntRange(0) index: Int, @NonNull mediaId: String) Requests that the SessionPlayer associated with the connected MediaSession adds the media item to the playlist at the index with the media ID. Index equals to or greater than the current playlist size (e.g. Integer#MAX_VALUE) will add the item at the end of the playlist. If index is less than or equal to the current index of the playlist, the current index of the playlist will be increased correspondingly. On success, a SessionResult would be returned with item added. ListenableFuture<SessionResult!> adjustVolume(direction: Int, flags: Int) Requests that the connected MediaSession adjusts the volume of the output that is playing on. The direction must be one of AudioManager#ADJUST_LOWER, AudioManager#ADJUST_RAISE, or AudioManager#ADJUST_SAME. The command will be ignored if the session does not support VolumeProviderCompat#VOLUME_CONTROL_RELATIVE or VolumeProviderCompat#VOLUME_CONTROL_ABSOLUTE. If the session is local playback, this changes the device's volume with the stream that session's player is using. Flags will be specified for the AudioManager. If the session is remote player (i.e. session has set volume provider), its volume provider will receive this request instead. Unit close() Releases this object, and disconnects from the session. After this, callbacks wouldn't be received.
