Android Stop Background Music

I’m very happy today, and still have hair 🙂
I’ve tested this and it works!!!

First, add this to your Manifest:

<uses-permission android:name="android.permission.GET_TASKS"/>

Second, add this to your ‘Home/Main’ Activity/Class:

  @Override
  protected void onPause() {
    if (this.isFinishing()){ //basically BACK was pressed from this activity
      player.stop();
      Toast.makeText(xYourClassNamex.this, "YOU PRESSED BACK FROM YOUR 'HOME/MAIN' ACTIVITY", Toast.LENGTH_SHORT).show();
    }
    Context context = getApplicationContext();
    ActivityManager am = (ActivityManager) context.getSystemService(Context.ACTIVITY_SERVICE);
    List<RunningTaskInfo> taskInfo = am.getRunningTasks(1);
    if (!taskInfo.isEmpty()) {
      ComponentName topActivity = taskInfo.get(0).topActivity; 
      if (!topActivity.getPackageName().equals(context.getPackageName())) {
        player.stop();
        Toast.makeText(xYourClassNamex.this, "YOU LEFT YOUR APP", Toast.LENGTH_SHORT).show();
      }
      else {
        Toast.makeText(xYourClassNamex.this, "YOU SWITCHED ACTIVITIES WITHIN YOUR APP", Toast.LENGTH_SHORT).show();
      }
    }
    super.onPause();
  }

And obviously replace xYourClassNamex with, well, Your Class Name 🙂

Now obviously you do not need the “Toasts” but it will tell you what is going on.
The very intersting thind is when you press BACK from your ‘Home/Main’ activity, you obviously get 2 Toasts, “YOU PRESSED BACK FROM YOUR ‘HOME/MAIN’ ACTIVITY”, and the 2nd Toast is “YOU SWITCHED ACTIVITIES WITHIN YOUR APP”. I believe I know why this happens, but it doesn;t matter because I call “player.stop();” from the 2 scenarios that mean my app is no longer being ‘used’. Obviously do more work than “player.stop();” if you need to 🙂 And also obvious you dont need the “else” for “YOU SWITCHED ACTIVITIES WITHIN YOUR APP”, because there is no reason to “stop/pause” the background music, which is what i needed, but if you DO need to do something when new activities are started, well here you go 🙂

Hope this helps anyone looking to know when the user “leaves/exits/is done with” the app 🙂

THANKS FOR ALL OF THE COMMENTS POSTS AND HELP EVERYONE!!! YAY!

EDIT-

This part has to be in EVERY activity’s onPause:

Context context = getApplicationContext();
        ActivityManager am = (ActivityManager) context.getSystemService(Context.ACTIVITY_SERVICE);
        List<RunningTaskInfo> taskInfo = am.getRunningTasks(1);
        if (!taskInfo.isEmpty()) {
          ComponentName topActivity = taskInfo.get(0).topActivity; 
          if (!topActivity.getPackageName().equals(context.getPackageName())) {
            player.stop();
            Toast.makeText(xYourClassNamex.this, "YOU LEFT YOUR APP", Toast.LENGTH_SHORT).show();
          }
        }

so you’ll know if the user left your app from ANY of the activities. this is good to know 🙂
