@PerActivity
@Subcomponent(modules = arrayOf(ApplicationModule::class))
interface ActivityComponent {
    fun inject(app: OneAccountApplication)
}

@Singleton
@Component(modules = arrayOf(ApplicationModule::class))
interface ApplicationComponent {

fun inject(syncService: SyncService)
@ApplicationContext fun context(): Context
fun application(): Application
fun ribotsService(): OneAccountService
fun preferencesHelper(): PreferencesHelper
fun databaseHelper(): DatabaseHelper
fun dataManager(): DataManager
}

@ConfigPersistent
@Component(dependencies = arrayOf(ApplicationComponent::class))
interface ConfigPersistentComponent {
    fun activityComponent(activityModule: ActivityModule): ActivityComponent
}

@Module
class ActivityModule(private val mActivity: Activity) {

    @Provides
    internal fun provideActivity() = mActivity

    @Provides
    @ActivityContext
    internal fun providesContext() = mActivity
}

@Module
class ApplicationModule(val mApplication: Application) {

    @Provides @Singleton
    internal fun provideApplication() = mApplication

    @Provides
    @ApplicationContext
    internal fun provideContext() = mApplication

    @Provides
    @Singleton
    internal fun provideOneAccountService() = OneAccountService.Creator.newOneAccountService()

apply plugin: 'kotlin-kapt'

dependencies {

    final DAGGER_VERSION = '2.8'
    def daggerCompiler = "com.google.dagger:dagger-compiler:$DAGGER_VERSION"
    annotationProcessor daggerCompiler
    testAnnotationProcessor daggerCompiler
    androidTestAnnotationProcessor daggerCompiler
    compile  "com.google.dagger:dagger:$DAGGER_VERSION"
}
kapt {
    generateStubs = true
}

基本上，这个IThttps://github.com/ribot/android-boilerplate变成了Kotlin。

Answer 1

Kotlin使用的是kapt而不是Android插件中的annotationprocessor。

您需要在build.gradle文件中包含并使用以下内容：

kapt {
    generateStubs = true
}
dependencies {
    // ...
    kapt daggerCompiler
}
