No inject registered. You must explicitly add it to the 'injects' option in one of your modules

Question

Hi I'm new to dagger and trying to study it with simple android app.

I'm getting error from the title even if there is module that injects this view. Could anyone help me figure out why it does not inject view ?

Here is my main module for app:

@dagger.Module(injects = {App.class, MainActivity.class}, complete = false)
public class AppModule {
    private final App app;
    public AppModule(App app) { this.app = app; }
    @Provides @Singleton public App provideApp() { return app; }
}

another module that injects my view:

@Layout(R.layout.sidemenu)
public class SidemenuScreen implements Blueprint{
    @Override public String getMortarScopeName() { return getClass().getName(); }
    @Override public Object getDaggerModule() { return new Module();}

    @dagger.Module(injects= SidemenuView.class, addsTo = AppModule.class)
    public static class Module { 
       public Module() {}
    }

    @Singleton public static class Presenter extends ViewPresenter<SidemenuView> {
        @Inject Presenter() {}
        @Override protected void onLoad(Bundle savedInstanceState) {super.onLoad(savedInstanceState); }
        @Override protected void onSave(Bundle outState) { super.onSave(outState); }
    }
}

As you can see SidemenuScreen.Module injects SidemenuView and addsTo AppModule. Am I wrong ?

ObjectGraph is created like this in onCreate() method of my Application class :

    ObjectGraph objectGraph = ObjectGraph.create(new AppModule(this));
    objectGraph.inject(this);
    rootScope = Mortar.createRootScope(BuildConfig.DEBUG, objectGraph);

view that should be injected

public class SidemenuView extends LinearLayout {
    @Inject SidemenuScreen.Presenter presenter;

    public SidemenuView(Context context) {this(context, null); }
    public SidemenuView(Context context, AttributeSet attrs) { this(context, attrs, 0); }
    public SidemenuView(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
        Mortar.inject(context, this);
    }
}

and activity that uses all this stuff:

public class MainActivity extends Activity {
    private MortarActivityScope activityScope;
    @Inject App app;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_main);

        Blueprint screen = getScreenFromIntent(getIntent());

        if (screen != null) {
            MortarScope parentScope = Mortar.getScope(getApplication());
            activityScope = Mortar.requireActivityScope(parentScope, screen);
            activityScope.onCreate(savedInstanceState);

            Mortar.inject(this, this);
        }

        SlidingMenu menu = new SlidingMenu(this);
        menu.attachToActivity(this, SlidingMenu.SLIDING_WINDOW);
        menu.setMenu(R.layout.sidemenu);
    }
}

Here used this Sliding menu lib:

So when menu.setMenu(R.layout.sidemenu); called it inflates view and Mortar.inject(context, this); is called from the SidemenuView constructor where error occurs.

Here is backstack:

Answer 1

So, I removed addsTo from submodules, added complite=false, library=true to submodules and added includes in AppModule and now it works. But I still can't get why it did not work as I did it before. The way it is done is a bit inconvenient because each time I implement new module I need to go to AppModule and add this module in list of included modules. It breaks an Open/Closed principle so I am still interested if there is a way to add new module with addsTo=AppModule.class.

Any suggestions ? Thanks.
