Android Development Guidelines

Android开发指南

Kotlin and Jetpack Compose Fundamentals

Kotlin与Jetpack Compose基础

  • 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
  • 使用带有现代语言特性的Kotlin 1.9+
  • 优先为新UI组件使用Jetpack Compose
  • 使用Compose状态管理（@State、@Remember、@ViewModel）
  • 利用Kotlin Coroutines处理异步操作
  • 使用Kotlin Flow实现响应式流
  • 遵循Kotlin编码规范

Android Architecture Patterns

Android架构模式

  • 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
  • MVVM：结合ViewModel与LiveData/StateFlow使用
  • Clean Architecture：分离数据层、领域层与表示层
  • Repository Pattern：抽象数据源
  • 使用Hilt实现依赖注入
  • 将业务逻辑与UI代码分离
  • 使用接口实现抽象与测试
