<AndroidInjector.Factory <? extends android.support.v4.app.Fragment >>> не может быть предоставлен без аннотируемого метода @Provides
Когда я использую AndroidInjector как ниже для non supportLibrary
class MainApplication: DaggerApplication() {
override fun applicationInjector(): AndroidInjector<MainApplication> {
return DaggerAppComponent.builder().application(this).build()
}
}
@Component(modules = [AndroidInjectionModule::class, ActivityBuilder::class])
interface AppComponent: AndroidInjector<MainApplication> {
@Component.Builder
interface Builder {
@BindsInstance
fun application(application: MainApplication): Builder
fun build(): AppComponent
}
}
@Module
abstract class ActivityBuilder {
@ContributesAndroidInjector(modules = [MainActivityModule::class])
abstract fun bindMainActivity(): MainActivity
}
class MainActivity : DaggerActivity() {
@Inject lateinit var info : Info
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_main)
my_text.text = info.text
}
}
class Info {
val text = "Hello Dagger Android"
}
@Module
class MainActivityModule {
@Provides
fun getInfo() = Info()
}
Все работает хорошо. Однако, когда я перехожу на версию поддержки
class MainApplication: dagger.android.support. DaggerApplication() {
override fun applicationInjector(): AndroidInjector<MainApplication> {
return DaggerAppComponent.builder().application(this).build()
}
}
@Component(modules = [AndroidInjectionModule::class, ActivityBuilder::class])
interface AppComponent: AndroidInjector<MainApplication> {
@Component.Builder
interface Builder {
@BindsInstance
fun application(application: MainApplication): Builder
fun build(): AppComponent
}
}
@Module
abstract class ActivityBuilder {
@ContributesAndroidInjector(modules = [MainActivityModule::class])
abstract fun bindMainActivity(): MainActivity
}
class MainActivity : DaggerAppCompatActivity() {
@Inject lateinit var info : Info
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_main)
my_text.text = info.text
}
}
class Info {
val text = "Hello Dagger Android"
}
@Module
class MainActivityModule {
@Provides
fun getInfo() = Info()
}
У меня есть эта ошибка. Что вызывает это?

Видимо у меня AndroidSupportInjectionModule
вместо AndroidInjectionModule
т.е.
@Component(modules = [AndroidInjectionModule::class, ActivityBuilder::class])
в
@Component(modules = [AndroidSupportInjectionModule::class, ActivityBuilder::class])
