[android-developers] Cant create handler inside thread that has not called looper.prepare() exception being thrown

[Akash Paul]

Hi have written some code which is supposed to send data via a http request 
object in android, However i know the data is being sent or posted but the 
UI thread does not like the way i have done things can anyone advise please?

Code: 

async class definition: 

private class Connection extends AsyncTask{
    @Override
    protected Object doInBackground(Object[] objects){
        try{
            PostData(R.id.fullscreen_content, 3);
           }
                catch(IOException exception){
                    exception.printStackTrace();
                }
                return null;
            }
}

button click action:  
/** Called when the user clicks the Happy button */
public void happy_click(View view) throws IOException {
    try{
        new Connection().execute();
        report_success();
    }
    catch(Exception exception){
        messageBox("Response was not successful","Failed to process response" + 
exception.getMessage());
    }
}


PostData method: 


protected void PostData(Integer Question_ID,Integer ResponseChosen_ID) throws 
IOException {
    try{
        URL url = new URL("http://cce.swlgroup.com/";);
        HttpURLConnection conn = (HttpURLConnection)url.openConnection();

        HttpClient httpClient = new DefaultHttpClient();
        HttpPost post = new HttpPost(conn.getURL().toString());
        conn.setRequestMethod("POST");

        conn.connect();
        Date date = new Date();
        SimpleDateFormat dt = new SimpleDateFormat("yyyy-MM-dd", Locale.UK);
        SimpleDateFormat time = new SimpleDateFormat("HH:mm:ss",Locale.UK);

        String nowDate = dt.format(date);
        String nowTime = time.format(date);

        String output = nowDate + "," + nowTime + ",";

        ArrayList<NameValuePair> params = new ArrayList<>();
        params.add(new BasicNameValuePair("Question 
ID",Question_ID.toString()));
        params.add(new BasicNameValuePair("Response_Chosen_ID", 
ResponseChosen_ID.toString()));
        params.add(new BasicNameValuePair("Timestamp", output));

        post.setEntity(new UrlEncodedFormEntity(params));
        HttpResponse response = httpClient.execute(post);
        BufferedReader reader = new BufferedReader(new 
InputStreamReader(response.getEntity().getContent()));
        StringBuilder builder = new StringBuilder();
        String line = "";
        while((line = reader.readLine()) != null){
            builder.append(params);
        }
        reader.close();
        messageBox("Response Submitted", "Response Submitted to server" + 
builder);
    }
    catch(Exception exception){
        messageBox("Response Failed",exception.getMessage());
    }
}


any advise would be much appreciated. Thanks for your time.
