Audio playback on Android looks straightforward until your app runs into OEM background task killers, audio focus changes, and mid-stream network handoffs.
AndroidX Media3 brings the player and the foreground service lifecycle together under a single MediaSession contract. Getting reliable gapless playback on variable networks still requires tuning ExoPlayer DefaultLoadControl.
By using an adaptive ring buffer with calibrated buffer windows, the player keeps decoding smoothly when mobile coverage drops for a few seconds. Pre-fetching the next track in the queue before the current one finishes avoids audio underruns and gaps between songs.
Staying alive in the background across MIUI, HyperOS, OneUI, and Pixel ROMs also requires strict adherence to Android 14+ ForegroundServiceType rules. Clean notification channels and audio focus callbacks keep playback running with the screen off without leaking wake locks.
The result is a player that starts right away, moves between tracks without silence or clicks, and stays stable in your pocket.
