How to keep the ActivityComponent

How to keep the ActivityComponent dependent on the ApplicationComponent? I get the unscoped error:

Error:(13, 1) error: com.joaquimley.daggerexample.di.component.ActivityComponent (unscoped) cannot depend on scoped components:
@singleton com.joaquimley.daggerexample.di.component.ApplicationComponent

Class missing

In the DemoApplication class you use DaggerApplicationComponent, and I can see that you import it (https://github.com/MindorksOpenSource/android-dagger2-example/blob/b8facb5d165638b456f7aeb4de5bef9ca5d288bc/app/src/main/java/com/mindorks/example/android_dagger2_example/DemoApplication.java#L8).
The problem is, there is no such file in the repository :/

[Question] why activityModule() is depreciated?

In mainactivity.java

    public ActivityComponent getActivityComponent() {
        if (activityComponent == null) {
            activityComponent = DaggerActivityComponent.builder()
                    .activityModule(new ActivityModule(this))
                    .applicationComponent(DemoApplication.get(this).getComponent())
                    .build();
        }
        return activityComponent;
    }

I am getting depreciate error on line no-30 i.e. .activityModule(new ActivityModule(this)).

If you could explain me why is it happening then it will be helpful?

How to use injectable class in non Activity/Fragment class

Hi ,
I'm currently using dagger 2 in my project. I'm unable to access injectable class through @Inject in non activity/fragment class. I have a handler class and want to use injectable in that class. Can u help me how to do this.

@Singleton
@Component(modules = {
        AndroidSupportInjectionModule.class,
        ApplicationModule.class,
        ActivityBuilder.class})
public interface ApplicationComponent extends AndroidInjector<DaggerApplication> {

    void inject(AppController appController);
    void inject(APIHandler apiHandler);

    @Override
    void inject(DaggerApplication daggerApplication);

    @Component.Builder
    interface Builder{
        @BindsInstance
        Builder application(Application application);
        ApplicationComponent build();
    }
}

This is my ApplicationComponent class I added a method inject(APIHandler apiHandler) in this and tried getting @Injent DataManager dataManager(injectable class) in ApiHandler class but getting it null, any other thing i need to do in APIHandler class.Let me know if i m missing something where as i m able to get it in activity and fragment

APIHandler class

public class APIHandler {
 
    /**
     * Activity reference object
     */
    private Activity mActivity;
    /**
     * Debug TAG
     */
    private String TAG = APIHandler.class.getSimpleName();
 @Inject
    DataManager dataManager;

    /**
     * Public Constructor for this class
     *
     * @param mActivity
     * @param webAPIResponseListener
     */
    public APIHandler(Activity mActivity, WebAPIResponseListener webAPIResponseListener) {
        this.mActivity = mActivity;
        this.mResponseListener = webAPIResponseListener;
        postAPICall();
    }
//API call
    public void postAPICall() {
//doing something
if(dataManager != null){
dataManager.setName();
}
}

DaggerActivityComponent missing

DaggerActivityComponent this class is missing in com.mindorks.example.android_dagger2_example.di.component package but still you used in
com.mindorks.example.android_dagger2_example.MainActivity class.
How?

DaggerActivityComponent file not found

The file not in the package- com.mindorks.example.android_dagger2_example.di.component.DaggerActivityComponent;

public ActivityComponent getActivityComponent() {
        if (activityComponent == null) {
            activityComponent = **DaggerActivityComponent**.builder()
                    .activityModule(new ActivityModule(this))
                    .applicationComponent(DemoApplication.get(this).getComponent())
                    .build();
        }
        return activityComponent;
}

Hi there,

DaggerActivityComponent in the MainActivity is deprecated, do you have a solution for overcoming this based on your tutorial which is fantastic by the way
