 }

my code in activity

 public void loadNextDataFromApi(int itemCount) {
    mService = ApiUtils.getSOService2();
}

public void loadAnswers(){
   mService.getFinalData().subscribeOn(Schedulers.io()).
  observeOn(AndroidSchedulers.mainThread())
                .subscribe(new Subscriber<NewsFeed>() {
                    @Override
                    public void onCompleted() { }
                    @Override
                    public void onError(Throwable e) {   }
                    @Override
                    public void onNext(NewsFeed response) {
                        Log.e("response", "response------------------>" + 
                       response.toString());
                    }
                });
}

Retrofit Client

public class RetrofitClient {

private static Retrofit retrofit = null;

public static Retrofit getClient(String baseUrl) {
    if (retrofit==null) {
        retrofit = new Retrofit.Builder()
                .baseUrl(baseUrl)
                .addCallAdapterFactory(RxJavaCallAdapterFactory.create())
                .addConverterFactory(GsonConverterFactory.create())
                .build();
    }
        return retrofit;
}
}

my Service

public interface SOService {
    @GET("16126940.json")
    Observable <NewsFeed> getFinalData();
}

in Utility i have kept method call

 public static final String HTTP_JSON_URL = "https://hackernews.firebaseio.com/v0/item/";
 public static SOService getSOService2() {
    return RetrofitClient.getClient(HTTP_JSON_URL).create(SOService.class); 
}

Answer 1

May be your error are ignored, As I can see your onError is blank. when you Hit service using RxJava and Retrofit. result will be successful or land in error. so onError should not be blank. put e.printStackTrace() at least. and also make sure you have called the method loadAnswers(). your provided code doesn't have that method called..

@Override
public void onError(Throwable e) {   
 e.printStackTrace()
}

I think you need to call the load answer method in below method.

 public void loadNextDataFromApi(int itemCount) {
    mService = ApiUtils.getSOService2();
    loadAnswers();
}
