Dagger2 error: module must be installed

Question

I tried to do SubScoping in Dagger2. However, I can not understand this compilation error: → ...MyApplicationModule must be set, which occurs in mine LogInFragment. If someone tries to shed light on this mistake. I really would be glad.

This is the MyApplication class :

public class MyApplication extends Application {

    @Override
    public void onCreate() {
        super.onCreate();
        MyInjector.initialize(this);
    }
}

This is the MyInjector class:

public enum MyInjector {
    INSTANCE;

    MyApplicationComponent myApplicationComponent;


    private MyInjector() {
    }

    public static void initialize(MyApplication myApplication) {

        MyApplicationComponent myApplicationComponent = DaggerMyApplicationComponent.builder()
                .myApplicationModule(new MyApplicationModule(myApplication))
                .build();
        INSTANCE.myApplicationComponent = myApplicationComponent;
    }

    public static MyApplicationComponent get() {
        return INSTANCE.myApplicationComponent;
    }

}

This is the MyApplicationComponent class:

@Component (modules = {MyApplicationModule.class}) 
public interface MyApplicationComponent { 

}

This is the class MyApplicationModule

@Module
public class MyApplicationModule {

    private final MyApplication myApplication;

    public MyApplicationModule(MyApplication myApplication) {
        this.myApplication = myApplication;
    }

    @Singleton
    @Provides
    SharedPreferences providesSharedPreferences(Context context) {
        return context.getSharedPreferences("My_Pref", Context.MODE_PRIVATE);
    }

    @Singleton
    @Provides
    public Context providesMyApplicationContext() {
        return this.myApplication.getApplicationContext();
    }

    @Singleton
    @Provides
    public LocationManager providesLocationService(Context context) {
        return (LocationManager) context.getSystemService(Context.LOCATION_SERVICE);
    }

    @Singleton
    @Provides
    public MyDatabaseManager providesMyDatabaseManager(Context context) {
        return MyDatabaseManager.getInstance(context);
    }

    @Singleton
    @Provides
    public AccountSystemModel providesAccountSystemModel(Context context) {
        return MyDatabaseManager.getInstance(context);
    }

    @Singleton
    @Provides
    public MyApplication providesMyApplication(){
        return this.myApplication;
    }

}

Here i'm trying subscope

This is the MyLogIn Component Class

@Singleton
@Component(modules = {MyApplicationModule.class}, dependencies = {MyApplicationComponent.class})
public interface LogInComponent {
    LogInPresenter signInPresenter();
}

here Compilation Errorcomes

This is MyLogInActivityFragment

@Override protected void injectDependencies() {
   logInComponent = DaggerLogInComponent.builder()
                    .myApplicationComponent(MyInjector.get())
                    .build();
}
