I am trying to fix bug when using new androidx with Dagger and kotlin. It works fine when using in Java written. But, when I switch it to kotlin, I got error: error: java.util.Map,javax.inject.Provider>> cannot be provided without an @Provides-annotated method. I am using Android Studio 3.2.1 Here is my code:
apply plugin: 'com.android.application'
apply plugin: 'kotlin-android'
apply plugin: 'kotlin-android-extensions'
apply plugin: 'kotlin-kapt'
implementation "com.google.dagger:dagger:2.13"
implementation "com.google.dagger:dagger-android:2.13"
implementation "com.google.dagger:dagger-android-support:2.13"
kapt "com.google.dagger:dagger-compiler:2.13"
kapt "com.google.dagger:dagger-android-processor:2.13"
My AppComponent:
@Singleton
@Component(modules = [AppModule::class, BuildersModule::class, NetworkModule::class])
interface AppComponent {
@Component.Builder
interface Builder {
@BindsInstance
fun application(app: BaseApp): Builder
fun build(): AppComponent
}
fun inject(app: BaseApp)
}
And my AppModule:
@Module
class AppModule {
@Provides
@Singleton
internal fun provideDataManager(): DataManager {
return DataManager()
}
@Provides
fun provideContext(app: BaseApp) : Context {
return app.applicationContext
}
@Provides
fun provideRemoteData (remoteRepository: RemoteRepository): RemoteContract {
return remoteRepository
}
}
So, my DaggerAppComponent is not generated because of that code. I even tried version 2.19 but got some other bugs. I read that they are trying to fix it. I would appreciate if there is some way around or any suggestion.
Oh, one more thing. In Java written, I had also AndroidSupportInjectionModule in AppComponent like and it worked fine:
@Singleton
@Component(modules = {AndroidSupportInjectionModule.class, AppModule.class, BuildersModule.class, NetworkModule.class})
public interface AppComponent {
@Component.Builder
interface Builder {
@BindsInstance
Builder application(BaseApp app);
AppComponent build();
}
void inject(BaseApp app);
}
If I add this in Kotlin version like bellow, I do not get above error anymore, but instead error when building is: Unresolved reference: DaggerAppComponent
@Singleton
@Component(modules = [
AndroidSupportInjectionModule::class,
AppModule::class,
BuildersModule::class,
NetworkModule::class
])
interface AppComponent {
@Component.Builder
interface Builder {
@BindsInstance
fun application(app: BaseApp): Builder
fun build(): AppComponent
}
fun inject(app: BaseApp)
}
