I have an android app that starts playing music right after the splash screen all the time while the user interacts with the app, using a singleton class for MediaPlayer, which is working perfectly, but I want to stop the music when the app exits or user switched to the other app, unfortunately which is not working properly, and I have to kill the app from the recent task to stop the music

If you have multiple activities while user is running the application, use LifecycleObserver to observe the state change in application class.

implementation "androidx.lifecycle:lifecycle-extensions:2.4.0"

Application Class

public class MyApplication extends Application implements LifecycleObserver {

@Override
public void onCreate() {
    super.onCreate();

    ProcessLifecycleOwner.get().getLifecycle().addObserver(this);
}

// Application level lifecycle events

@OnLifecycleEvent(Lifecycle.Event.ON_START)
public void onEnteredForeground() {
    //Log.d(TAG,"Application did enter foreground");
}

@OnLifecycleEvent(Lifecycle.Event.ON_STOP)
public void onEnteredBackground() {
   // Log.d(TAG,"Application did enter background");
}

}

For more info refer to - Handling lifecycle with Lifecycle Observers

use onPause() then make it stop playing music, after that onResume or onStart to play the music if user is back to app
