title: LoopJ AndroidAsyncHttp is returning response in OnFailure
body: <p>i am new to AndroidAsyncHttp.</p>
  
  <p>i created a class httptester :</p>
  
  <pre><code> private static AsyncHttpClient client = new AsyncHttpClient();
  
      public static void get(String url, RequestParams params, AsyncHttpResponseHandler responseHandler) {
          client.get(getAbsoluteUrl(url), params, responseHandler);
      }
  
      public static void post(String url, RequestParams params, AsyncHttpResponseHandler responseHandler) {
          client.post(getAbsoluteUrl(url), params, responseHandler);
      }
  
      private static String getAbsoluteUrl(String relativeUrl) {
          return  relativeUrl;
      }
  </code></pre>
  
  <p>and in my activity did the following: </p>
  
  <pre><code>RequestParams params = new RequestParams();
          params.put("FTID", HTTPRequestUserAuthentication.AppID);
          params.put("UUID", MainActivity.uuid);
          params.put("TYPE", "11");
          params.put("DateTimeStamp", DateTimeStamp);
          params.put("SDFVersionNb", SDFVersionNb);
  
          httptester.post(MainActivitySharedPref.GetValue(MyApplication.getContext(), "WebService_URL")+MyApplication.getContext().getResources().getString(R.string.url_get_user_data), params,new JsonHttpResponseHandler() {
              @Override
              public void onSuccess(int statusCode, Header[] headers, String responseString) {
                  super.onSuccess(statusCode, headers, responseString);
  
                  Log.e(TAG, "sucess: " + responseString);
  
              }
  
              @Override
              public void onFailure(int statusCode, Header[] headers, String responseString, Throwable throwable) {
                  Log.e(TAG, "failure: " + responseString);
                  Log.e(TAG, "failurecode: " + statusCode);
  
                  super.onFailure(statusCode, headers, responseString, throwable);
              }
  
          });
  </code></pre>
  
  <p>after calling the client, the correct response is being returned but it is being returned in OnFailure and not in OnSuccess. i also printed the status code in onfailure and it is 200 which supposedly should be OK. </p>
  
  <p>any help would be appreciated.</p>
