This player is really simple! Just two taps, and your audio/video files are up and running. After that, you can turn off the screen, use other apps, etc., and the music will continue playing in the background!
It was created as an attempt to experiment with some new technologies from Google: Jetpack Compose and media3. It's open-source: https://github.com/avsDeveloper/AVSPlayer
Enjoy it! :)
