我一直在關注來自谷歌的 GithubBrowserSample 作為我的參考。我剛剛通過實施到我的 MainActivity 中對匕首進行了最后的潤色，現在收到以下錯誤。除了包含我已經擁有的內容之外，似乎無法在其中找到太多內容。error: [Dagger/MissingBinding] [dagger.android.AndroidInjector.inject(T)] java.util.Map<java.lang.String,javax.inject.Provider<dagger.android.AndroidInjector.Factory<? extends androidx.fragment.app.Fragment>>> cannot be provided without an @Provides-annotated method.java.util.Map<java.lang.String,javax.inject.Provider<dagger.android.AndroidInjector.Factory<? extends androidx.fragment.app.Fragment>>> is injected atdagger.android.DispatchingAndroidInjector.<init>(…, injectorFactoriesWithStringKeys)dagger.android.DispatchingAndroidInjector<androidx.fragment.app.Fragment> is injected atcom.crosscare.MainActivity.dispatchingAndroidInjectorcom.crosscare.MainActivity is injected atdagger.android.AndroidInjector.inject(T)component path: com.crosscare.di.AppComponent ? com.crosscare.di.MainActivityModule_ContributeMainActivity.MainActivitySubcomponent主要活動：public class MainActivity extends AppCompatActivity implements HasSupportFragmentInjector {    @Inject    DispatchingAndroidInjector<Fragment> dispatchingAndroidInjector;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);    }    @Override    public DispatchingAndroidInjector<Fragment> supportFragmentInjector() {        return dispatchingAndroidInjector;    }}應用組件：@Singleton@Component(modules = {        AndroidInjectionModule.class,        AppModule.class,        MainActivityModule.class})public interface AppComponent {    @Component.Builder    interface Builder {        @BindsInstance Builder application(Application application);        AppComponent build();    }    void inject(CrosscareApp crosscareApp);}任何建議將不勝感激。
