Dependence injection at fragment using dagger


Step 1 : Add to activity module

@Subcomponent(modules = {ActivityModule.class})
public interface FragmentComponent {
void inject(HamburgerActivity mainActivity);


void inject(HomeScreenFragment homeScreenFragment);


}


Step 2: inject current fragment in onViewCreated


@Nullable@Overridepublic View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
    return inflater.inflate(R.layout.com_philips_lumea_treatment_done, null);
}

@Overridepublic void onViewCreated(View view, @Nullable Bundle savedInstanceState) {
    super.onViewCreated(view, savedInstanceState);

    // inject current fragment    ((Application) getActivity().getApplication()).getFragmentComponent().inject(this);


}




Step 3 : Register and Unregister




@Overridepublic void onStop() {
    super.onStop();
    if (eventing != null) {
        eventing.unregister(this);
    }
}

@Overridepublic void onStart() {
    super.onStart();
    if (eventing != null && !eventing.isRegistered(this)) {
        eventing.register(this);
    }
}

Gradle DSL method not found: 'compile()'





















  As the note of your project's  build.gradle  file suggests:  // NOTE: Do not place your application dependencies here; they belong  // in the individual module build.gradle files   Remove the 2 compile statements in that gradle file:  compile 'com.android.support:appcompat-v7:20.+'  compile 'com.google.android.gms:play-services:6.5.+'   And then make your other (module's)  build.gradle  dependencies look like this:  dependencies {      compile fileTree ( dir :  'libs' ,  include :  [ '*.jar' ])      compile 'com.android.support:appcompat-v7:21.0.3'      compile 'com.google.android.gms:play-services:6.5.+'  }
