Agent Skills: Android Architecture Standards

Apply Clean Architecture layering, modularization, and Unidirectional Data Flow in Android projects. Use when setting up Android project structure, placing code in Clean Architecture layers, configuring feature/core modules, or implementing UDF patterns. (triggers: build.gradle.kts, settings.gradle.kts, clean-architecture, module, layers, domain, UDF, unidirectional, feature module, core module, presentation layer, data layer)

Android Architecture Standards

Priority: P0 (CRITICAL)

1. Layer Your Project (Clean Architecture)

  • Domain: Pure Kotlin (No Android deps). Contains UseCases and Models.
  • Data: Repository impl, DataSources (API/DB). Maps DTO -> Domain.
  • UI: ViewModel + Composable. Maps Domain -> UiState.

See structure & examples for Clean Architecture layer examples.

2. Modularize by Feature and Core

  • Feature Modules: :feature:home, :feature:profile.
  • Core Modules: :core:ui (Design System), :core:network, :core:database.
  • App Module: DI Root and Navigation Guard.

See structure & examples for module configuration.

3. Enforce Unidirectional Data Flow (UDF)

  • Events: UI -> ViewModel (user actions flow UP).
  • State: ViewModel -> UI (StateFlow<UiState> flows DOWN).

4. Verify Jetpack Compose Integration

  • Hosting: Use setContent in Activity (No XML Layouts).
  • State: Hoist state to ViewModel using collectAsStateWithLifecycle.
  • Recomposition: Ensure Composable parameters are @Stable or @Immutable.
  • Navigation: Use Compose Navigation with Type-Safe destinations.

Anti-Patterns

  • No Logic in Activity: Host Navigation only.
  • No Repo in UI: Access data exclusively via ViewModel.
  • No Context in Domain: Keep Logic Pure.
