Dagger2 not resolving dependency all the way

Question

I have a MainActivity which injects Presenter, presenter object injects interactor and interactor object injects APIHelper. All the providers of presenter, interactor and APIHel

Answer 1

Change MainPresenterImpl & ListingInteractorImpl constructors to following and precede them with @Inject:

    @Inject
    public MainPresenterImpl(MainActivity activity, ListingInteractor interactor) {...}

    @Inject
    public ListingInteractorImpl(Context context, APIHelper helper) {...}

Then in your module implementation:

    @Provides
    @Singleton
    public MainViewPresenter providesMainPresenter(ListingInteractor interactor){
        return new MainPresenterImpl(activity, interactor);
    }

    @Provides
    @Singleton
    ListingInteractor providesInteractor(APIHelper helper){
        return new ListingInteractorImpl(activity, helper);
    }
