ExoPlayer stutters / stops after screen turns off or in background

Can I use GPS in background?

There are many misconceptions about the term “background”. Background as used here in the last post means only that the app is not not visible (eg after pressing the home button), but not closed. Background (tasks) means that an app can also do somthing if the app is closed. Kodular, AI2, Thunkable, AppBuilder, … can not run background tasks.

This is about a Foreground service (and not a Background service) to prevent Doze mode (and thus the stuttering / stopping of the sound in idle (sleep) mode).
