A polished audio playback app tailored for my personal library. I wanted something modern, reliable, and beautiful to use every day, so this project focuses on the practical features I care about most.
- Folder-based playlists – choose any folder on device storage and the app automatically builds a clean playlist for those tracks.
- Persistent playback – the chosen folder, current track, playback position, shuffle/repeat modes, and speed all come back exactly where I left them.
- Modern UI – Material 3 design with compact controls, haptic feedback on the important actions, and a tidy track detail sheet for metadata.
- Background ready – runs as a proper foreground media service, so playback continues safely when the app is closed, with lockscreen and notification controls.
- Dynamic scroll – the active song always stays in view; the playlist auto-scrolls whenever I move to the next or previous track.
- Kotlin + Jetpack Compose
- Media3 ExoPlayer & MediaSession
- DataStore (for preferences)
- Android 12+ compatible (min SDK 31)
