Can't get twitter user's follower count via Twitter API

I am having a hard time getting the number of followers a twitter user has.

I did follow the twitter rest api documentation and couldn’t find an answer to my problem. I am successfully making the call via their rest API and I am getting a “Success” call back but I don’t know what to parse my response into. Their documentation keeps saying “it returns a “collection of ids”. So I assumed I could parse the response into a List of ids (List) but that results a gson parsing error . I can successfully parse it into a JSONOBject but that ends up being empty.

Here’s the relevant code:

package com.boomer.omer.kollabstr.backend.twitteroauth;

import com.twitter.sdk.android.core.models.User;

import org.json.JSONObject;

import java.util.List;

import retrofit.Callback;
import retrofit.http.GET;
import retrofit.http.Query;


    public interface TwitterGetFollowerCountApiClient {

         @GET("/1.1/followers/ids.json")
        void getFollowerCount(@Query("user_id")Long id,
                          @Query("screen_name")String screenname,
                          @Query("cursor")Long cursor,
                          @Query("stringify_ids")Boolean sids,
                          @Query("count")Long count,
                          Callback<JSONObject> users);
}

Then I send/handle the request from:

 private void createSocialMediaObject(final TwitterSession twitterSession){
    getKollabstrTwitterApiClient().getFollowerCountService().
            getFollowerCount(twitterSession.getUserId(),
                    null,
                    null,
                    null,
                    null,
                    new Callback<JSONObject>() {
                @Override
                public void success(Result<JSONObject> result) {
                    SocialMedia twitter = new SocialMedia();
                    twitter.setUsername(twitterSession.getUserName());
                    twitter.setUserid(Long.toString(twitterSession.getUserId()));
                    twitter.setSocialMediaType(SocialMediaType.TWITTER);
                    //twitter.setImpact(result.data.size());
                   // Log.d(TAG,"FOLLOWERS:" + Integer.toString(result.data.size()));
                    Users user = SessionManager.getInstance().getCurrentUser();
                    user.getProfile().getSocialMediaAccounts().add(twitter);
                    SessionManager.getInstance().updateUser(user);
                    Log.d("FOLLOWER",Integer.toString(result.data.length()));
                }

                @Override
                public void failure(TwitterException exception) {
                    Log.d(TAG,"FOLLOWER ERROR:" + exception.toString());

                }
            });



}

I followed their documentation here : https://dev.twitter.com/rest/reference/get/followers/ids

I want to get a list of ids so I can get the size of it , which should be the number of followers according to their page. But even though I can get a success callback(Which I assume indicates a successful query being done) I can not figure out what is it that the response should be parsed into.

Any help is appreciated. Please don’t simply refer me to other libraries to get this done.

    I found the answer. I just had to parse the response into Response class from Retrofit. Then convert that into a JSON object.

     public JSONObject responseToJSON(Response response){
    BufferedReader reader = null;
    StringBuilder sb = new StringBuilder();
    JSONObject jsonObject = null;
    try {

        reader = new BufferedReader(new InputStreamReader(response.getBody().in()));

        String line;

        try {
            while ((line = reader.readLine()) != null) {
                sb.append(line);
            }
        } catch (IOException e) {
            e.printStackTrace();
        }
    } catch (IOException e) {
        e.printStackTrace();
    }


    String result = sb.toString();

    try {jsonObject=new JSONObject(result);
    } catch (JSONException e) {
        e.printStackTrace();
    }

    return  jsonObject;
}

    Try this code that I use in some of my projects to get Twitter integration working:

    Twitter4j setup

    Download twitter4j library (jar files), add the following to your libs folder and Right-click them from the libs folder to Add as Library. That means your build.gradle file will look something like this:

    dependencies{

   ...
   compile files('libs/twitter4j-async-4.0.4.jar')
   compile files('libs/twitter4j-core-4.0.4.jar')
}

    Now, you are ready to use this library to connect with Twitter.

    Assumption: You have already created a Twitter application on the Developer account on Twitter.

    Next, regardless of how you want to do the requests (AsyncTask, Service, etc):

    //this sample code searches for twitter accounts

//rest of your code  here

@Override
protected ResponseList<User> doInBackground(String... params) {

    String location = "kansas city";

    try {
        //mTwitter is your Twitter instance!
        return mTwitter.searchUsers(location, 20);
    }catch (TwitterException e){
        e.getMessage();
    }
    return null;
}

@Override
protected void onPostExecute(ResponseList<User> response){
    if (response != null){
        progress.dismiss();

        if (response.size() == 0 ){
            //you got no results back; zero
        }else{

            //you can loop through the response list

            User u = response.get(0);

            Log.i("USERCOUNT", "THE COUNT: " + u.getFollowersCount());
       }
    }
}

    So, you can quickly get your results with this library;

    I hope this helped you and let me know if you need further assistance!
