Android - asynchttpclient send back resul from onSuccess or onFailure

Question

Hy!

I want to make some http calls to a restserver from my android client. I created a class for rest calls. I followed the http://loopj.com/android-async-http/ description:

My question is that how can I send back anything from onSucces() method? For example I have the following function:

public class RestController {
    public String getName() throws JSONException {

        TwitterRestClient.get(url, null, new JsonHttpResponseHandler() {
            @Override
            public void onSuccess(int statusCode, Header[] headers, JSONObject response) {
            String name;
            try {
                name = response.getString("name");

            } catch (JSONException e) {
                e.printStackTrace();
            }
         }
       });
   }
}

How can I return the name to getName function?

function () {
  ...
  String name = restController.getName();
  ...
  do something with the name

Thank you very much! I will apreciate any kind of help!
