This is a sample app that goes along with two Medium articles I wrote on how to add FirebaseUI Authentication to your Android app. If you would like to follow the step by step tutorials you can check them out below:

Part 2: https://medium.com/@nabeelj/implementing-signing-out-deleting-accounts-and-upgrading-anonymous-users-with-firebaseui-3f5f9dc235ab?source=friends_link&sk=0da22e654cf15c046259f258edf7e8e5

Note: You are free to use any part of this code for your own personal or commercial works. However, if you want to run this application on your device on its own you will need to provide your own google-services.json file.
