隐藏功能模块

问题描述

我向android项目添加了动态功能模块。我知道，剑柄不支持此类模块。我在Google文档中找到了解决此问题的方法。

Hilt in feature modules

我的项目结构如下

• 应用-具有应用活动的主模块
• 常见
  • utils-具有所有Android模块通用功能的模块
    • 数据库-包括DatabaseModule（hilt）
    • 网络-包括http客户端和NetworkModule（hilt）
    • 注入-包括MapBox模块依赖项类
• 核心
• 功能
  • mapBoxFeature-包括MapBoxComponent和MapBoxModule

@Component(
    dependencies = [MapBoxModuleDependencies::class],modules = [MapBoxModule::class]
)
interface MapBoxComponent {

    fun inject(fragment: MapBoxMapFragment)

    @Component.Builder
    interface Builder {
        fun context(@BindsInstance context: Context): Builder
        fun appDependencies(mapBoxModuleDependencies: MapBoxModuleDependencies): Builder
        fun build(): MapBoxComponent
    }
}

@Module
class MapBoxModule {

    @Provides
    fun provideGetMapTaskUseCase(repository: MapTaskRepository): GetMapTasksUseCase = GetMapTasksUseCase(repository)

    @Provides
    fun provideMapTaskRepository(dataSource: MapTaskDbDataSource): MapTaskRepository = MapTaskRepositoryImpl(dataSource)

    @Provides
    fun provideMapTaskDbDataSource(dbRepository: TaskDbRepository): MapTaskDbDataSource = MapTaskDbDataSourceImpl(dbRepository)
}

@EntryPoint
@InstallIn(ApplicationComponent::class)
interface MapBoxModuleDependencies {

    fun provideDatabase(@ApplicationContext context: Context): AppDatabase

    fun provideTaskDao(appDatabase: AppDatabase): TaskDao

    fun provideTaskDbRepository(dao: TaskDao): TaskDbRepository
}

@Module
@InstallIn(ApplicationComponent::class)
object DatabaseModule {

    @Singleton
    @Provides
    fun provideDatabase(@ApplicationContext context: Context) = Room.databaseBuilder(
        context,AppDatabase::class.java,DatabaseConstants.databaseName
    ).allowMainThreadQueries().build()

    @Singleton
    @Provides
    fun provideTaskDao(appDatabase: AppDatabase) = appDatabase.taskDao()

    @Singleton
    @Provides
    fun provideTaskDbRepository(dao: TaskDao): TaskDbRepository = TaskDbRepositoryImpl(dao)

...

override fun onCreate(savedInstanceState: Bundle?) {
        fun setDaggerMapBoxComponent() {
            DaggerMapBoxComponent.builder()
                .context(requireContext())
                .appDependencies(
                    EntryPointAccessors.fromApplication(
                        requireContext(),MapBoxModuleDependencies::class.java
                    )
                )
                .build()
                .inject(this)
        }
...

当我运行一个项目时，它会收到如下日志：

> Task :app:kaptDebugKotlin

* What went wrong:
Execution Failed for task ':app:kaptDebugKotlin'.

   > java.lang.reflect.InvocationTargetException (no error message)

有人知道是什么问题吗？

解决方法

在MapboxModuleDependencies中，您应该只这样定义TaskDbRepository：

@EntryPoint
@InstallIn(ApplicationComponent::class)
interface MapboxModuleDependencies {

    fun provideTaskDbRepository(): TaskDbRepository
}
