Answer 1

onDestroy: The final call you receive before your activity is destroyed. This can happen either because the activity is finishing (someone called finish() on it), or because the system is temporarily destroying this instance of the activity to save space.

Here is an example......

 public void onDestroy() {
              
   super.onDestroy();

 }
