title: How to track android fragments using firebase analytics
body: <p>In my android application, I have an Activity that has 3 or 4 fragments that can be attached in sequence based on some user or server events.</p>
  
  <p>I would like to track all these fragments as screens in firebase.</p>
  
  <p>So ideally, if possible, is there an API i can invoke in the onCreate of the fragments, and tell firebase that user is currently in fragment1, fragment2 or fragment3? </p>
