Dagger 2 error: dependency “cannot be provided without an @Inject constructor” while it actually annotated with @Inject

Question

I\'ve started using Dagger 2 and faced strange issue that looks like a bug to me.

I have 3 modules, that are composed into one subcomponent, which in turn extends/pl

Answer 1

Seems it is the same kinda error dagger reports for many mistakes. In my case, my target injection was expecting concrete class (Presenter) where as the module that provides presenter was returning only the interface (DemoContract.Presenter)

So changed from

@Inject
public Presenter mDemoPresenter;  

to

@Inject
public DemoContract.Presenter mDemoPresenter;

and module that provides presenter looks like this:

@Module
public class DiDemoPresenterModule {
    private final DemoContract.View mView;

    DiDemoPresenterModule(MainActivity mView) {
        this.mView = mView;
    }

    @Provides
    public DemoContract.Presenter providesDemoPresenter(Repository repository) {
        return new DemoPresenter(repository, mView);
    }
}
