Audio-only playback (AudioOnlySampleApp)

Plays audio-only assets with a media-style background playback notification, so audio and its transport controls keep working when the app is in the background. Layers on:

• a scrollable track list backed by a Brightcove playlist
• shuffle and repeat controls

Key files

File	Responsibility
MainActivity.java	Loads the playlist via Catalog, wires the shuffle and repeat controls, and attaches the background playback notification.
VideoListAdapter.java	RecyclerView adapter listing the tracks; a tap switches the playing track.

See the Playback README for shared setup and requirements.
