This is where I used CodeLab to build a simple chat app with Firebase as the backend. It includes:
- Firebase for management of users and their messages
- Google Authorization
- Firebase Realtime Database
- Ability to receive reengagement notifications if sent by an admin from Firebase
- Ability to send install invites
- Firebase analytics, for tracking user flows
- A banner ad
- Crash reports via Firebase
- Support for cloud-based Espresso tests via Firebase Test Lab
