Dagger2 Circular Dependency Error - dagger-2

Question

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".
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
}
}
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.
Please help me.

Answer 1

In App.kt you need to initialize component with the application context. the line
AppInjector.init(this)
should be inside the Activity i.e. splashActivity in which you're going to inject the dependencies.

Answer 2

The above mentioned error message might also appear, because kotlin stdlib is not declared as dependency. So adding e.g. implementation("org.jetbrains.kotlin:kotlin-stdlib:1.3.60") in your build.gradle(.kts) file might also help.
