无法从AppComponentFactory访问单例服务的初始化？

public class MyAppComponentFactory extends AppComponentFactory {
    @Override
    public Activity instantiateActivity(ClassLoader cl, String className, Intent intent) throws ClassNotFoundException, InstantiationException, IllegalAccessException {
        return super.instantiateActivity(cl, className, intent);
    }

    @Override
    public Application instantiateApplication(ClassLoader cl, String className) throws ClassNotFoundException, InstantiationException, IllegalAccessException {
        return super.instantiateApplication(cl, className);
    }

    @Override
    public BroadcastReceiver instantiateReceiver(ClassLoader cl, String className, Intent intent) throws ClassNotFoundException, InstantiationException, IllegalAccessException {
        return super.instantiateReceiver(cl, className, intent);
    }

    @Override
    public ContentProvider instantiateProvider(ClassLoader cl, String className) throws ClassNotFoundException, InstantiationException, IllegalAccessException {
        return super.instantiateProvider(cl, className);
    }

    @Override
    public Service instantiateService(ClassLoader cl, String className, Intent intent) throws ClassNotFoundException, InstantiationException, IllegalAccessException {
        return super.instantiateService(cl, className, intent);
    }
}

@HiltAndroidApp
public class MyApplication extends Application {
    @Override
    public void onCreate() {
        super.onCreate();
        // Hilt will handle the rest
    }
}

public class MyApplication extends Application {
    private MySingletonService mySingletonService;

    @Override
    public void onCreate() {
        super.onCreate();
        mySingletonService = new MySingletonService();
    }

    public MySingletonService getMySingletonService() {
        return mySingletonService;
    }
}

public class MyAppComponentFactory extends AppComponentFactory {
    @Override
    public Activity instantiateActivity(ClassLoader cl, String className, Intent intent) throws ClassNotFoundException, InstantiationException, IllegalAccessException {
        Activity activity = super.instantiateActivity(cl, className, intent);
        MyApplication application = (MyApplication) activity.getApplication();
        MySingletonService mySingletonService = application.getMySingletonService();
        // 使用 mySingletonService
        return activity;
    }
}

@Module
public class AppModule {
    @Provides
    @Singleton
    public MySingletonService provideMySingletonService() {
        return new MySingletonService();
    }
}
