如何使用dagger2在Android服务中注入单例

我正在尝试将单身经理添加到Android服务中.问题是注入的管理器与ViewModel中的管理器不同.

匕首组件

@Singleton
@Component(modules = {ApplicationModule.class, AppScreenModule.class, ServiceModule.class})
public interface AppComponent {

    void inject(App application);

    void inject(OpportunisticService opportunisticService);

    @Component.Builder
    interface Builder {
        AppComponent build();

        Builder applicationModule(ApplicationModule applicationModule);
    }
}

模块

@Module
class ApplicationModule {    
    private final App mApp;

    ApplicationModule(App app) {
        mApp = app;
    }

    @Provides
    @Named("ApplicationContext")
    Context provideContext() {
        return mApp.getApplicationContext();
    }

    @Provides
    App provideApplication() {
        return mApp;
    }

    @Provides
    PeersManager providePeersManager() {
        return new PeersManager();
    }
}

@Module
abstract class ServiceModule {

    @ContributesAndroidInjector
    abstract OpportunisticService bindOpportunisticService();
}

初始化

public class Components {
    private static AppComponent sComponent;

    public static void initialize(App app) {
        // Initialize the AppComponent
        Preconditions.checkState(sCompOnent== null, "AppComponent already initialized");
        sCompOnent= DaggerAppComponent.builder()
                                       .applicationModule(new ApplicationModule(app))
                                       .build();
    }

    public static AppComponent app() {
        if (BuildConfig.DEBUG)
            Preconditions.checkState(sCompOnent== null, "AppComponent not initialized");
        return sComponent;
    }
}

public class App extends Application implements HasActivityInjector, HasServiceInjector {
    @Inject
    DispatchingAndroidInjector mActivityDispatchingAndroidInjector;

    @Inject
    DispatchingAndroidInjector mServiceDispatchingAndroidInjector;

    @Override
    public void onCreate() {
        super.onCreate();

        // Initialize the AppComponent
        Components.initialize(this);
        Components.app().inject(this);
    }

    @Override
    public AndroidInjector activityInjector() {
        return mActivityDispatchingAndroidInjector;
    }

    @Override
    public AndroidInjector serviceInjector() {
        return mServiceDispatchingAndroidInjector;
    }
}

声明PeerManager:

@Singleton
public class PeersManager {

    @Inject
    public PeersManager() {
    }
}

使用PeersManager:

public class ViewModel {
    private final PeersManager mPeersManager;

    @Inject
    public ViewModel (PeersManager peersManager) {
        mPeersManager = peersManager;
    }
}

public class OpportunisticService extends Service {
    @Inject
    PeersManager mPeersManager;

    @Override
    public void onCreate() {
        super.onCreate();
        AndroidInjection.inject(this);
    }
}

问题是,ViewModel.mPeersManager它不同于OpportunisticService.mPeersManager,并且我希望它们是相同的,因为它PeersManager被标记为单身.

我希望这是因为不同的发生AndroidInjectorS代表Activity/ Fragment和Service.
