android asycntask มันลง Catch ตลอดเลยครับลองดีบัคติดตอน JSONObject object = new JSONObject(content);

public class HttpTask extends AsyncTask<String, Void, JSONObject> {

        @Override
        protected JSONObject doInBackground(String... urls) {

            try {
                HttpClient httpclient = new DefaultHttpClient();
                HttpGet httpGet = new HttpGet(urls[0]);
                httpGet.setHeader("Accept", "application/json");
                httpGet.addHeader("Content-Type", "application/json; charset=UTF-8");
                httpGet.addHeader("Access-Control-Allow-Origin", "*");
                HttpResponse response = httpclient.execute(httpGet);
                HttpEntity entity = response.getEntity();

                // Read the contents of an entity and return it as a String.
                String content = EntityUtils.toString(entity);
                JSONObject object = new JSONObject(content);

                return object;
            } catch (IOException e) {
                e.printStackTrace();
            } catch (JSONException e) {
                e.printStackTrace();
            }

            return null;
        }
    }
