Dagger2 Circular Dependency Error

[ahmtbrk]

I am using dagger2 2.16 version for dependency injection inside mine android project. I examine a lot of examples, and although I do not have a similar approach I get the error of "circular dependency".

If I remove the ActivityBuilderModule from the AppComponent, the project is compiled without problems. But if you add to the modules section, the project gives the error below.

error: [ComponentProcessor:MiscError] dagger.internal.codegen.ComponentProcessor was unable to process this interface because not all of its dependencies could be resolved. Check for compilation errors or a circular dependency with generated code.

Mine source code; AppComponent.kt

@Singleton
@Component(
        modules = [
            AndroidSupportInjectionModule::class,
            AppModule::class,
            ActivityBuilderModule::class]
)
interface AppComponent {
    @Component.Builder
    interface Builder {
        @BindsInstance
        fun application(application: Application): Builder

        fun build(): AppComponent
    }

    fun inject(app: App)
}

App.kt

class App : Application(), HasActivityInjector {

    @Inject
    lateinit var dispatchingAndroidInjector: DispatchingAndroidInjector<Activity>

    override fun onCreate() {
        super.onCreate()
        AppInjector.init(this)
        initOneSignal()
    }

    private fun initOneSignal() = OneSignal.startInit(this).setNotificationOpenedHandler(CustomNotificationOpenedHandler()).inFocusDisplaying(OneSignal.OSInFocusDisplayOption.Notification).init()

    override fun activityInjector() = dispatchingAndroidInjector
}

ActivityBuilderModule.kt

@Module
abstract class ActivityBuilderModule {
    @ContributesAndroidInjector
    abstract fun contributeSplashActivity(): SplashActivity
}

AppModule.kt

@Module(includes = [(ViewModelModule::class)])
class AppModule {

    @Singleton
    @Provides
    fun provideContext(app: Application): Context = app.applicationContext;

    @Singleton
    @Provides
    fun provideApiService(client: OkHttpClient): ApiService {
        return Retrofit.Builder()
                .baseUrl(Constants.baseUrl)
                .client(client)
                .addConverterFactory(GsonConverterFactory.create())
                .addCallAdapterFactory(RxJava2CallAdapterFactory.create())
                .build()
                .create(ApiService::class.java)
    }

    @Singleton
    @Provides
    fun provideOkHttpClient(interceptor: HttpLoggingInterceptor): OkHttpClient {
        return OkHttpClient.Builder().addInterceptor(interceptor).build()
    }

    @Singleton
    @Provides
    fun provideHttpLoggingInterceptor(): HttpLoggingInterceptor {
        val interceptor = HttpLoggingInterceptor()
        interceptor.level = HttpLoggingInterceptor.Level.BODY
        return interceptor
    }
}

AppInjector.kt

object AppInjector {

    fun init(app: App) {
        DaggerAppComponent.builder().application(app)
                .build().inject(app)

        app.registerActivityLifecycleCallbacks(object : Application.ActivityLifecycleCallbacks {
            override fun onActivityCreated(activity: Activity, savedInstanceState: Bundle?) {
                handleActivity(activity)

            }
        })
    }

    private fun handleActivity(activity: Activity) {
        if (activity is HasSupportFragmentInjector) {
            AndroidInjection.inject(activity)

                                override fun onFragmentCreated(
                                        fm: FragmentManager,

                                }
                            }, true
                    )
        }
    }
}

This appears to be a question - please use StackOverflow with the dagger-2 tag instead, as that is a better forum for questions.

i had the same problem please tell me the answer

check if your all files have specificated the package -> "package com.something.blahblah...."

@kochchy Thank you very much. I realized that one of my file didn't have the package name inside

I ran into this because of a Gradle cache issue. Running ./gradlew --no-build-cache clean assembleDebug got passed this, and the app successfully built. I did end up having to blow away the remote build cache as well to ensure it stuck.
