FirebaseTalk
Example app I live programmed during my presentation for the GDG Android Meetup group in Stockholm at Expressen.
The app shows how to implement Firebase Authentication, using FirebaseUI, and Firebase Firestore to create an app with account management and chat in less than 150 lines of code.
If you want to run the app you need to create a project in Firebase, enable authentication using email / password and add the google-services.json file to the project.
