TunesFeed is an example project that demonstrates use of the latest Android Development best-practices for UI (JetPack/Lifecycle), Navigation, MVVM (ViewBinding and DataBinding), Kotlin Coroutines, etc.
- Leverages approaches from Google's latest Android Architecture Blueprints per https://github.com/android/architecture-samples
- A single-activity UI architecture, with Bottom Navigation Bar using the Navigation Component to manage fragment operations; see https://developer.android.com/guide/navigation/navigation-getting-started
- A Presentation Layer that re-uses a single, parameterized fragment and a ViewModel per screen or feature; e.g. the
FeedListFragmentis parameterized byFeedTypefor each "tab" in the app (UI component re-use); see https://developer.android.com/topic/libraries/architecture/viewmodel - Reactive UIs using LiveData observables and Data Binding; changes to underlying data propagate via observation, so are updated only when necessary.
- An abstracted data layer using the Service Locator pattern to provide either a mocked or real implementation for an abstract repository interface, describing the web-service / data-source layer.
- Service layer leverages Kotlin Coroutines (suspend functions; launched in viewModelScope) per https://developer.android.com/topic/libraries/architecture/coroutines
- Entity objects and DTOs are correctly distinct per proper Separation of Concerns and SOLID architecture principles.
