Android Dialog throwing not attached to window manager

I have the below code that throws an exception. Other then a try/catch, is there anyway to fix this?

@Override
    public void onDestroy() {

            if(dialog != null && dialog.isShowing())
                dialog.dismiss();

        super.onDestroy();
    }

Exception

When onDestroy() is called, it may that the views are detached and you will get this exception. You should move your code to onPause()

@Override
public void onPause() {
    super.onPause();
    
    if(dialog != null && dialog.isShowing())
    {
       dialog.dismiss();
    }
}
