This video (episode 2 of 6) starts the coding for our project. We setup the Firebase project, add Google sign in, navigate to the MainActivity, and allow signing out of our app. Code we wrote: https://github.com/rpandey1234/EmojiStatus/commit/9719cea11e0d87f0de96eff88023c95eddfb69b1 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.
