Android (Kotlin) Patterns

Battle-tested patterns for modern Android apps.

• Architecture
  • MVVM with StateFlow
  • MVI with sealed intents
  • Clean Architecture (UseCases/Repo)
• Data & Concurrency
  • Repository + Retrofit + Room
  • Coroutines + Flow basics
• DI & Navigation
  • DI with Hilt
  • Navigation with Jetpack
• UI
  • Compose state hoisting

Try it

Quickstart a new Compose project in Android Studio (recommended). Or via CLI:

# Using Gradle init (Kotlin/JVM project; then add Android bits in Studio)
gradle init --type kotlin-application

# Or create in Android Studio: New Project → Empty Activity → Jetpack Compose
# Then paste files from the guides into appropriate packages (ui/, data/, di/).

Tips

• For Hilt, add the Gradle plugins and dependencies, annotate @HiltAndroidApp on your Application, and use hiltViewModel() in composables.
• For Retrofit/Moshi/Room, add dependencies and DI modules from the guides, and point base URLs to jsonplaceholder for quick tests.
