Android 安卓的匕首2“；如果没有@Providers注释的方法，则无法提供；

我正在尝试为Android使用Dagger2v2.11的最新版本 这是我的代码：

AppComponent

：

@Singleton
@Component(modules = {
        AndroidInjectionModule.class,
        AppModule.class,
        ActivityBuildersModule.class,
        FragmentBuildersModule.class
})
public interface AppComponent {
    void inject(MyApplication myApplication);

    @Component.Builder
    interface Builder {
        @BindsInstance
        Builder application(Application application);

        AppComponent build();
    }

    @ExceptionRequestsQualifier
    ExceptionRequestsServices exceptionRequestsServices();

}

AppModule

：

@Module(includes = {ActivityModule.class, FragmentModule.class})
public class AppModule {

    @Provides
    CompositeDisposable provideCompositeDisposable() {
        return new CompositeDisposable();
    }

    @Provides
    @ExceptionRequestsQualifier
    ExceptionRequestsServices provideExceptionRequests() {
        return new Retrofit.Builder()
                .addConverterFactory(GsonConverterFactory.create())
                .addCallAdapterFactory(RxJava2CallAdapterFactory.create())
                .baseUrl(APIConstants.EXCEPTION_REQUESTS_BASE_URL)
                .build()
                .create(ExceptionRequestsServices.class);
    }

    @Singleton
    @Provides
    NetworkManager provideNetworkManager(Application app) {
        return new NetworkManager(app);
    }

}

@Module
public abstract class ActivityBuildersModule {

    @ActivityScope
    @ContributesAndroidInjector
    abstract ExceptionRequestsActivity contributeExceptionRequestsActivity();

}

@Module()
public abstract class ActivityModule {

    @Provides
    @ActivityScope
    static ExceptionRequestsMvpPresenter<ExceptionRequestsMvpView> bindExceptionRequestsPresenter(
            ExceptionRequestsPresenter<ExceptionRequestsMvpView> presenter) {
        return presenter;
    }

}

@Module
public abstract class FragmentBuildersModule {

    @FragmentScope
    @ContributesAndroidInjector
    abstract AddApplicantFragment contributeAddApplicantFragment();

    @FragmentScope
    @ContributesAndroidInjector
    abstract PledgeFragment contributePledgeFragment();

}

@Module()
public abstract class FragmentModule {

    @Provides
    @FragmentScope
    static AddApplicantMvpPresenter<AddApplicantMvpView> bindAddApplicantPresenter(
            AddApplicantPresenter<AddApplicantMvpView> presenter) {
        return presenter;
    }

    @Provides
    @FragmentScope
    static PledgeMvpPresenter<PledgeMvpView> bindPledgePresenter(
            PledgePresenter<PledgeMvpView> presenter) {
        return presenter;
    }

}

添加应用程序MVPPresenter

：

public class AddApplicantPresenter<V extends AddApplicantMvpView> extends BasePresenter<V> implements AddApplicantMvpPresenter<V> {

    @Inject
    @ExceptionRequestsQualifier
    ExceptionRequestsServices mExceptionRequestsServices;

    @Inject
    NetworkManager mNetworkManager;

    @Inject
    public AddApplicantPresenter(CompositeDisposable compositeDisposable) {
        super(compositeDisposable);
    }

}

@FragmentScope
public interface AddApplicantMvpPresenter<V extends AddApplicantMvpView> extends MvpPresenter<V> {

    void addApplicant(String name, String qatarId,
                      String date, String mobile,
                      ChosenImage chosenImage);

}

碎片范围

：

@Scope
@Retention(RetentionPolicy.RUNTIME)
public @interface ActivityScope {
}

@Scope
@Retention(RetentionPolicy.RUNTIME)
public @interface FragmentScope {
}

模块

和

组件

不能有不同的

范围

您可以让

组件

拥有多个

作用域

，这可以解决这个问题。 尝试将其移动到不同的组件，并将其作为组件依赖项添加

我希望将来他们能像我在项目中那样解决这个问题。 目前，Dagger2允许模块带有NoScope和单示波器。这应该与您的组件相匹配

拇指规则：：不同的作用域有不同的组件。 对于您的应用程序，您需要三个组件，

FragmentComponent

（

FragmentScope

）：-（理想情况下，这应该是

ActivityComponent

）

ApplicationComponent

（

Singleton

）

---

阅读有关作用域的更多信息。

您可能的副本仅提供

@ExceptionRequestsQualifier exceptionrequests服务

，但您的组件试图公开

exceptionrequests服务

，DavidMedenjak我将

@ExceptionRequestsQualifier

添加到

ExceptionRequestsServices

中，并更新了我的问题和错误日志。您不能从

@Singleton

组件提供

@ActivityScope

'd。在

AppModule

上查看您的子模块，那么我如何才能做到这一点呢？
