Question 1

Android Architecture Samples vs Architecture Templates: which should I use?

Accepted Answer

Use Android Architecture Samples for learning and comparing architectural patterns with a simple app, as it's educational. For a ready-to-use project scaffold, go with Architecture Templates, which are designed for quick starts.

Question 2

How to implement Hilt dependency injection using these samples?

Accepted Answer

The samples use Hilt throughout, with examples in the application class and ViewModels. Look for @Inject annotations and Hilt modules in the codebase to see how dependencies are provided and injected in a layered architecture.

Question 3

What testing frameworks are used in Android Architecture Samples?

Accepted Answer

It employs JUnit for unit tests, Espresso for UI tests, and shared tests for emulator/device runs. The tests cover ViewModel logic, repository interactions, and end-to-end flows, demonstrating a robust testing approach.

Question 4

Can I use Jetpack Compose with these architecture samples?

Accepted Answer

Yes, the current branch uses Jetpack Compose and Navigation Compose for a single-activity architecture, showing how to integrate Compose with modern patterns like MVVM and reactive data flows.

Question 5

How does the data layer handle local and remote data?

Accepted Answer

It uses Room for local storage and a fake remote data source in the repository pattern. The repository abstracts these sources, but note that real network integration isn't implemented, limiting practical use for live apps.

Question 6

What are the mock and prod product flavors for?

Accepted Answer

Mock flavor uses fake data to ease development and testing, while prod flavor simulates a production environment. This setup helps test different scenarios without code changes, as mentioned in the README.
