Dagger-错误：[Dagger / MapKeys]相同的地图键已绑定多次-Android

Question

我从我的项目中的匕首起诉，但出现以下错误：

error: [Dagger/MapKeys] The same map key is bound more than once for java.util.Map<java.lang.Class<?>,javax.inject.Provider<dagger.android.AndroidInjector.Factory<?>>>
public abstract interface AppComponent extends dagger.android.AndroidInjector<dagger.android.DaggerApplication> {
                ^
      @Binds @dagger.multibindings.IntoMap @dagger.multibindings.ClassKey(com.Courses.CoursesActivity.class) dagger.android.AndroidInjector.Factory<?> com.Courses.module.CoursesActivityProvider_CoursesActivity.bindAndroidInjectorFactory(com.Courses.module.CoursesActivityProvider_CoursesActivity.CoursesActivitySubcomponent.Factory)
      @Binds @dagger.multibindings.IntoMap @dagger.multibindings.ClassKey(com.Courses.CoursesActivity.class) dagger.android.AndroidInjector.Factory<?> com.di.ActivityBuilder_BindCoursesActivity.bindAndroidInjectorFactory(com.di.ActivityBuilder_BindCoursesActivity.CoursesActivitySubcomponent.Factory)
      java.util.Map<java.lang.Class<?>,javax.inject.Provider<dagger.android.AndroidInjector.Factory<?>>> is injected at
          dagger.android.DispatchingAndroidInjector(injectorFactoriesWithClassKeys, …)
      dagger.android.DispatchingAndroidInjector<java.lang.Object> is injected at
          dagger.android.support.DaggerAppCompatActivity.androidInjector
      com.Courses.CoursesActivity is injected at
          dagger.android.AndroidInjector.inject(T) [com.di.AppComponent → com.di.ActivityBuilder_BindCoursesActivity.CoursesActivitySubcomponent]
  The following other entry points also depend on it:
      dagger.android.AndroidInjector.inject(T) [com.di.AppComponent → com.di.ActivityBuilder_BindCoursesActivity.CoursesActivitySubcomponent → com.Courses.module.CoursesActivityProvider_CoursesActivity.CoursesActivitySubcomponent]

这里是AppScoped：

@Scope
@kotlin.annotation.Retention(AnnotationRetention.RUNTIME)
annotation class AppScoped

和CoursesActivityScope：

@Scope
@kotlin.annotation.Retention(AnnotationRetention.RUNTIME)
annotation class CoursesActivityScope

和ActivityBuilder：

@Module
abstract class ActivityBuilder {
    @ContributesAndroidInjector(modules = [CoursesActivityProvider::class])
    abstract fun bindCoursesActivity(): CoursesActivity?
}

和AppComponent：

@AppScoped
@Component(modules = [
    AndroidSupportInjectionModule::class,
    AppModule::class,
    ActivityBuilder::class])
interface AppComponent : AndroidInjector<DaggerApplication?> {
    fun inject(app: App?)
    override fun inject(instance: DaggerApplication?)
    @Component.Builder
    interface Builder {
        @BindsInstance
        fun application(application: Application?): Builder?

        fun build(): AppComponent?
    }
}

和AppModule：

@Module
abstract class AppModule {
    @Binds
    abstract fun provideContext(application: Application?): Context?
}

和App：

import dagger.android.support.DaggerApplication;
@AppScoped
class App : DaggerApplication() {
    override fun applicationInjector(): AppComponent? {
        val appComponent = DaggerAppComponent
            .builder()
            .application(this)
            ?.build()
        appComponent!!.inject(this)
        return appComponent
    }
}

这是我的Activity：

@CoursesActivityScope
class CoursesActivity : DaggerAppCompatActivity(){
  ......
}

但是让我克服错误。

Answer 1

我将此class编辑为：

@Module
abstract class ActivityBuilder {
    @CoursesActivityScope
    @ContributesAndroidInjector(modules = [CoursesActivityModule::class])
    abstract fun bindCoursesActivity(): CoursesActivity?
}
