# The last callback in the lifecycle of an activity is onDestroy()...

The last [callback](https://www.mindstick.com/articles/152/using-the-callback) in the [lifecycle](https://yourviews.mindstick.com/view/10392/how-is-the-vendor-lifecycle-impacting-the-energy-sector-in-north-america) of an [activity](https://www.mindstick.com/blog/23160/fidgetsguide-exercise-guides-newsletters) is onDestroy().

Usually, the system will call onPause() and onStop() before calling onDestroy().

### Answer by Prateek sharma

to understand this scenario let's look at the example -

```
@Override
public void onCreate(Bundle savedInstanceState){
//calling super class
 super.onCreate(savedInstanceState);
//some work here
//calling finish()
finish();
}
@Override
public void onResume(){
//you need to tell the super class about this invocation, so
super.onResume();
//do your work
}
@Override
public void onPause(){
//you need to tell the super class about this invocation, so
super. onPause();
//do your work
}
@Override
public void onStop(){
//you need to tell the super class about this invocation, so
super. onStop();
}
@Override
public void onDestroy(){
//you need to tell the super class about this invocation, so
super. onDestroy ();
}
```

when the user calls the finish() method this will directly trigger the onDestroy() method without going through onPause() and onStop().
