App level lifecyclce hook not page level

I want something like android lifecycle in ionic. Is there any method in ionic at app level like android onStop or onDestroy method.

Closest would probably be the pause event of Platform.

What about OnDestroy when implemented by your AppComponent:

export class AppComponent implements OnInit, OnDestroy {

  ...

  public ngOnDestroy() {

  }

}
