Firebase and Google Cloud integration

Firebase is used for:

  • Authentication
  • Realtime NoSQL database
  • Analytics and crashlytics
  • Machine Learning model deployment
  • Remote Config

Google Cloud Platform is required for OAuth2 authentication and accessing Firebase services.

Setup Firebase​

  1. Create a new Firebase project here.
  2. Add an Android app to the project. Use a distinct package name, NOT illyan.jay.
  3. Add Authentication, Firestore Database, Analytics, Crashlytics, Machine Learning, Performance and Remote Config services.
  4. Select Project Settings and download google-services.json.
  5. Don't forget to add the SHA-1 key to the Firebase project settings. You can generate the hey with the command ./gradlew signingReport.
  6. Setup Authentication to use Google Sign-In.

Google Cloud Platform​

To use Firebase services, you need to add the SHA-1 key to the Google Cloud Platform project.

  1. If not yet done, link your Firebase project to Google Cloud Platform.
  2. Under APIs & Services ➡️ Credentials, select Android key (auto created by Firebase).
  3. Set application restrictions to Android apps and add the SHA-1 key with your package name.
  4. If deploying to production, don't forget to publish OAuth to production. To do that, navigate to Oath consent screen under Credentials menu.
