DefaultHttpClient httpClient = new DefaultHttpClient();
            HttpGet httpGet = new HttpGet(url);
            HttpResponse httpResponse = httpClient.execute(httpGet);
            HttpEntity httpEntity = httpResponse.getEntity();
            String tokens = EntityUtils.toString(httpEntity, "utf-8");
            Gson token_gson = new Gson();
            object = token_gson.fromJson(tokens, JsonObject.class);

            JsonElement jsonElement = object.get("errcode");
