You can do as followed:

When your app is not started/ running and you start from an notification, onCreate gets called.

@Override
protected void onCreate(Bundle savedInstanceState) {
   super.onCreate(savedInstanceState);
}

When your app is running (background or foreground), and you start a new intent from an notification this method gets called: (if you are using singleTop)

@Override
protected void onNewIntent (Intent intent){

}

To detect whether your app is running back- or foreground, you can simply set a boolean in onPause/onResume:

@Override
protected void onResume() {
  super.onResume();
  runningOnBackground = false;
}

@Override
protected void onPause() {
  super.onPause();
  runningOnBackground = true;
}

Hope it helps!
