Android MVVM Architecture: Sample App

Screenshots

Programming Practices Followed

1. Android Architectural Components
2. Dagger 2 for Dependency Injection
3. MVVM & LiveData
4. Retrofit with Okhttp
5. Repository Pattern
6. Coroutine, Coroutine Flow
7. DataBinding
8. JUnit and Mockito for Unit Testing - Pending ( In Future )

Branches

There are different branches as per the practices followed, namely:

• master - Master Branch, Empty.
• mvvm_viewmodel_livedata_retrofit - MVVM Implementation with LiveData
• mvvm_with_dagger_implementation - Dagger DI based implementation
• coroutine_implementation - Kotlin Coroutine implementation
• coroutine_flow_implementation - Kotlin Coroutine Flow Implementation
