I've a really weird problem with AsyncTask class and operation that they're made. My code looks that...

private class BackgroundTask extends AsyncTask < Void, Void, JSONArray >
    {
        private ProgressDialog pdia;

        @Override
        protected void onPreExecute(){
            super.onPreExecute();
            pdia = new ProgressDialog(LoginActivity.this);
            pdia.setMessage("...");
            pdia.setCanceledOnTouchOutside(false);
            pdia.show();
        }

        @Override
        protected Integer doInBackground(Void... params) {

            SocketIOClient.connect(AsyncHttpClient.getDefaultInstance(), "http://192.168.1.2:3000", new ConnectCallback() {
                @Override
                public void onConnectCompleted(Exception ex, SocketIOClient client) {
                    if (ex != null) {
                        ex.printStackTrace();
                        return;
                    }
                    client.on("MyEvent", new EventCallback() {
                        @Override
                        public void onEvent(JSONArray argument, Acknowledge acknowledge) {
                            ////////////
                            //
                            // HERE'S MY OUTPUT IN `argument` VARIABLE
                            //
                            ///////////
                        }
                    });
                }
            });

            // return null;
            // I need that variable here.
        }

        protected void onPostExecute(JSONArray result){
            super.onPostExecute(result);
            Log.d("Result...", result.toString());
            pdia.dismiss();
        }
    }

Data what I need are in onConnectCompleted, but I need it in doInBackground. I can't make global variable for output, because post will be executed to short. So my question is, how can I return my data?
