Hushabye

Foreground service — media playback demonstration

Hushabye plays continuous sleep sounds. It uses a mediaPlayback foreground service (FOREGROUND_SERVICE_MEDIA_PLAYBACK) so audio keeps playing when the app is backgrounded or the screen is locked. The clip shows:
  1. Starting a sound in the app.
  2. The media-playback notification with transport controls.
  3. Audio continuing after pressing Home (app backgrounded).
  4. Media controls on the lock screen while playback continues.
