How to pause background music in an app?

Question

Java

There is a class for creating background music:

public class MyService extends Service {
    MediaPlayer player;

    @Override
    public IBinder onBind(Intent intent) {
        return null;
    }

    @Override
    public void onCreate() {
        player = MediaPlayer.create(this, R.raw.fon);
        player.setLooping(true); // зацикливаем
    }

    @Override
    public void onDestroy() {
        player.stop();
    }

    @Override
    public void onStart(Intent intent, int startid) {
        player.start();
    }
}

Next, on the very first screen (loading screen), I launch the player and the music starts working in all windows:
startService(new Intent(this, MyService.class));
Next, in each class, I write the following code to stop the music after the application is minimized:

// свернули приложение
    @Override
    public void onPause() {
        Play.super.onPause();
        stopService(new Intent(this, MyService.class)); // остановить песню
    }

    // развернули приложение
    @Override
    public void onResume() {
        Play.super.onResume();
        startService(new Intent(this, MyService.class)); // запустить песню
    }

It turns out that every time the application is minimized / maximized, the music starts playing again (this is understandable, because I restart the class)
Question: how can I pause the background melody after the user minimizes the application and continue the song from the same place after expanding?

Answer 1

You don't need to call stopService in onPause, you are killing the service.
You should call startService(new Intent(this, MyService.class),putExtra("pause", true));
with the parameter that you catch in the service.
In the service in the onStartCommand method, check for the presence of a parameter
if intent.getBooleanExtra("pause", false) == true then player.pause()
