Android Kotlin

This gets you set up with modern Android patterns: Kotlin coroutines with StateFlow for reactive ViewModels, Jetpack Compose for UI, Hilt for dependency injection, and MockK for testing. The source includes actual project structure with clean architecture layers (data, domain, presentation), plus working examples of Flow-based repositories that cache locally with Room and fetch from network. The Gradle config uses Kotlin DSL and shows the current BOM setup for Compose. It's opinionated about coroutine dispatchers and StateFlow over LiveData, which is the right call for new projects. If you're still writing XML layouts or using Dagger without Hilt, this will modernize your stack fast.
