# Android 开发插件 (dev-android)

## 架构：MVVM + Hilt

## 代码规范

```kotlin
@HiltViewModel
class TaskViewModel @Inject constructor(
    private val taskRepository: TaskRepository
) : ViewModel() {

    private val _tasks = MutableStateFlow<List<Task>>(emptyList())
    val tasks: StateFlow<List<Task>> = _tasks.asStateFlow()

    fun fetchTasks() {
        viewModelScope.launch {
            taskRepository.getTasks()
                .collect { _tasks.value = it }
        }
    }
}

@Composable
fun TaskListScreen(viewModel: TaskViewModel = hiltViewModel()) {
    val tasks by viewModel.tasks.collectAsState()
    LazyColumn {
        items(tasks) { task -> TaskItem(task = task) }
    }
}
```

## 构建

```bash
./gradlew assembleDebug      # Debug 构建
./gradlew assembleRelease    # Release 构建
