What you'll build

You extend the intermediate ViewModel/StateFlow app with Room database persistence, Hilt dependency injection, Firebase Authentication, DataStore preferences, WorkManager background sync, unit and UI tests, CI/CD, Crashlytics, and Google Play publishing.

Prerequisites

• Complete the Intermediate tier (ViewModel + StateFlow + Navigation Compose)
• Android Studio Hedgehog or later
• A Firebase project (for Auth, Crashlytics; free tier)
