Android Development Guidelines

Kotlin and Jetpack Compose Fundamentals

• Use Kotlin 1.9+ with modern language features
• Prefer Jetpack Compose for new UI components
• Use Compose state management (@State, @Remember, @ViewModel)
• Leverage Kotlin Coroutines for asynchronous operations
• Use Kotlin Flow for reactive streams
• Follow Kotlin coding conventions

Android Architecture Patterns

• MVVM: Use with ViewModel and LiveData/StateFlow
• Clean Architecture: Separate data, domain, and presentation layers
• Repository Pattern: Abstract data sources
• Implement dependency injection with Hilt
• Separate business logic from UI code
• Use interfaces for abstraction and testing

Android Jetpack Libraries

• Room: Use for local database persistence
• WorkManager: Use for background tasks
• Navigation Component: Use for app navigation
• DataStore: Use for key-value storage
• Paging 3: Use for paginated data
• CameraX: Use for camera functionality
• BiometricPrompt: Use for biometric authentication
• AppCompat: Use for backward compatibility

Material Design 3 Guidelines

• Follow Material Design 3 principles
• Use Material 3 components and theming
• Implement proper elevation and shadows
• Use Material Icons for consistency
• Support different screen sizes and densities
• Implement responsive layouts
• Support Dark Theme properly
• Use motion and animations appropriately

Android Permissions and Security

• Request runtime permissions properly
• Use permission best practices
• Implement proper certificate pinning
• Use Android Keystore for secure storage
• Follow security best practices
• Implement proper network security configuration
• Use ProGuard/R8 for code obfuscation

Google Play Store Submission

• Follow Google Play Developer Policies
• Prepare app bundle (AAB) for upload
• Prepare screenshots and store listing
• Test with Internal and Closed Testing tracks
• Handle app updates and versioning properly
• Comply with privacy and data collection policies
• Use Play Console for distribution and analytics

Android Performance Optimization

• Use Android Profiler for performance analysis
• Optimize APK/AAB size with code shrinking
• Use leak detection tools (LeakCanary)
• Implement proper image loading and caching
• Optimize network requests and data transfer
• Reduce app startup time
• Use efficient layouts and view binding
• Optimize battery usage

Android Testing Frameworks

• JUnit: Use for unit tests
• Espresso: Use for UI tests
• Compose Testing: Use for Compose UI tests
• Robolectric: Use for local unit tests
• MockK: Use for mocking in tests
• Truth: Use for assertion libraries
• Write testable code with dependency injection
