title: Handling onActivityResult in Android app having more than one activity
body: <p>In my android app, I have a main activity which creates two other sub activites through intent. Now, both the sub activity return result to the main activity. In my main activity,
  how do I handle two "onActivityResult(int requestCode, int resultCode, Intent data)" since it cant have two methods with same name in a given class. Hope my question is clear..</p>
  
  <p>Thanks</p>
