我正在遵循Google的GithubBrowserSample使用的架构。但是在构建项目时遇到了麻烦。

我已将项目迁移到 AndroidX。我在 StackOverflow 上尝试了许多可用的答案，但都没有成功。这是我在构建时面临的构建异常：

e:/windows/Apps/Verifi/VerifiApp/app/build/tmp/kapt3/stubs/debug/com/verifi/di/component/AppComponent.java:11: error: [Dagger/MissingBinding] [dagger.android.AndroidInjector.inject(T)] java.util.Map<java.lang.Class<? extends androidx.lifecycle.ViewModel>,javax.inject.Provider<androidx.lifecycle.ViewModel>> cannot be provided without an @Provides-annotated method.
public abstract interface AppComponent extends dagger.android.AndroidInjector<com.verifi.VerifiApp> {
                ^
      java.util.Map<java.lang.Class<? extends androidx.lifecycle.ViewModel>,javax.inject.Provider<androidx.lifecycle.ViewModel>> is injected at
          com.verifi.viewmodel.AppViewModelFactory.<init>(creators)
      com.verifi.viewmodel.AppViewModelFactory is injected at
          com.verifi.ui.auth.AuthActivity.appViewModelFactory
      com.verifi.ui.auth.AuthActivity is injected at
          dagger.android.AndroidInjector.inject(T)
  component path: com.verifi.di.component.AppComponent ? com.verifi.di.module.ActivityBindingModule_AuthActivity.AuthActivitySubcomponent

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':app:kaptDebugKotlin'.

验证应用程序

class VerifiApp: Application(), HasActivityInjector {

    @Inject
    lateinit var dispatchingAndroidInjector: DispatchingAndroidInjector<Activity>

    override fun onCreate() …

这就是我要提供的方式ViewModelFactory：

@Suppress("UNCHECKED_CAST")
@Singleton
class ViewModelFactory @Inject constructor(
    private val viewModels: MutableMap<Class<out ViewModel>, Provider<ViewModel>>
) : ViewModelProvider.Factory {

    override fun <T : ViewModel?> create(modelClass: Class<T>): T = viewModels[modelClass]?.get() as T
}

@Target(AnnotationTarget.FUNCTION, AnnotationTarget.PROPERTY_GETTER, AnnotationTarget.PROPERTY_SETTER)
@kotlin.annotation.Retention(AnnotationRetention.RUNTIME)
@MapKey
annotation class ViewModelKey(val value: KClass<out ViewModel>)

这就是我绑定的方式ViewModelFactory：

@Suppress("unused")
@Module
abstract class ViewModelModule  {
    @Binds
    internal abstract fun bindViewModelFactory(factory: ViewModelFactory): ViewModelProvider.Factory

    @Binds
    @IntoMap
    @ViewModelKey(MainViewModel::class)
    internal abstract fun mainViewModel(viewModel: MainViewModel): ViewModel
}

在构建期间收到以下错误：

di/Injector.java:9: error: [Dagger/MissingBinding] java.util.Map<java.lang.Class<? extends androidx.lifecycle.ViewModel>,javax.inject.Provider<androidx.lifecycle.ViewModel>> cannot be provided without …
