This video (episode 1 of 6) shows the functionality of our app and how we're going to use the various Firebase services. Google Play link for the published Android app: https://play.google.com/store/apps/details?id=edu.stanford.rkpandey.emojistory Follow me on Twitter: https://twitter.com/rpandey1234 In this series, we build an Android app combining various Firebase services (Authentication, Cloud Functions, and Firestore) to allow users to update and view emoji-only statuses. The user is able to create or sign in to their account with Google. The app is less than 200 lines of Kotlin code.
