        super.onCreate(savedInstanceS         


        

Answer 1

Bundle is used to save & recover state information for your activity. In instances like orientation changes or killing of your app or any other scenario that leads to calling of onCreate() again, the savedInstanceState bundle can be used to reload the previous state information. Familiarity with this article about Activity lifecycle will help.
