Hi Phawin,

Sorry about this! It is a known error...we discussed this in the Forum a while back and have linked to it as a "Known Issue" in the Teacher Notes on the video page. Check out the solution (and discussion) in that other thread.

Try replacing the whole doInBackground method with this version:

@Override
protected JSONObject doInBackground(Object... params) {
    int responseCode = -1;
    JSONObject jsonResponse = null;
    StringBuilder builder = new StringBuilder();
    HttpClient client = new DefaultHttpClient();
    HttpGet httpget = new HttpGet("http://www.grepscience.com/api/get_recent_summary/");

    try {
        HttpResponse response = client.execute(httpget);
        StatusLine statusLine = response.getStatusLine();
        responseCode = statusLine.getStatusCode();

        if (responseCode == HttpURLConnection.HTTP_OK) {
            HttpEntity entity = response.getEntity();
            InputStream content = entity.getContent();
            BufferedReader reader = new BufferedReader(new InputStreamReader(content));
            String line;
            while((line = reader.readLine()) != null){
                builder.append(line);
            }

            jsonResponse = new JSONObject(builder.toString());
        }
        else {
            Log.i(TAG, String.format("Unsuccessful HTTP response code: %d", responseCode));
        }
    }
    catch (JSONException e) {
        logException(e);
    }
    catch (Exception e) {
        logException(e);
    }           

    return jsonResponse;
}
