Firebase authentication
Tonight you will complete the Google tutorial: "Add Firebase to Your Android Project" either by yourself or with a small group:
https://firebase.google.com/docs/android/setup
Your mission is to follow the tutorial and authenticate a user. You pick which way you authenticate the user. It can be through their Google account or Facebook account or...you decide.

Once you have successfully authenticated the user, prove you have by getting their display name or email:

Submit your code here or show me tonight.
