Question 1

How to set up Clean Architecture in Android with Kotlin?

Accepted Answer

This project provides a base template with Data, Domain, and Presentation layers. Start by cloning the repository and adapting the UseCase and Repository patterns to your specific business logic and data sources, ensuring dependencies are injected via Dagger2.

Question 2

Clean Architecture vs MVVM in Android: which should I use?

Accepted Answer

Clean Architecture offers stricter separation of concerns and testability, ideal for complex apps with heavy business logic. MVVM with Android Architecture Components is simpler, more integrated with modern UI tools like LiveData, and better for rapid development or Compose-based projects.

Question 3

How does Clean Architecture handle networking in Android?

Accepted Answer

In this project, networking is managed in the Data layer using Retrofit with RxJava2 observables, allowing reactive data flows that are decoupled from business logic in the Domain layer and easily mocked for testing.

Question 4

What are the best practices for testing Clean Architecture Android apps?

Accepted Answer

Focus on unit testing Domain layer UseCases with mocked Data layer repositories. This project facilitates this with JUnit and Mockito, ensuring business logic is isolated and verifiable without UI or network dependencies.

Question 5

Can I use Clean Architecture with Jetpack Compose?

Accepted Answer

This specific project uses MVP and traditional views, but Clean Architecture principles can be adapted to Compose by replacing the Presentation layer with Composable functions and ViewModels, though it requires significant modification of the base template.

Question 6

Is RxJava necessary for Clean Architecture in Android?

Accepted Answer

No, but this project uses RxJava2 for reactive programming and thread management. Alternatives like Kotlin coroutines and Flow can be integrated, though it requires overhauling the Base UseCase class and threading approach, adding development overhead.
