On Android, background playback is owned by a generated foreground service and native MediaSession. This supplies notification and lock-screen metadata, transport controls, audio focus and guarded progress polling.

Honest limits

Normal source playback, explicit downloaded files, queues, playlists, favourites, seek, shuffle and repeat are supported. ApkPy does not currently promise DRM, automatic adaptive audio quality, crossfade, a smart cache or gapless playback for every codec/device combination.

Use Audio, playlists and Spotify for the complete API.
