http get in android async task

Question

When i implement this it says "NetworkOnMainThreadException".

Could someone post an example which works?

I have tried many different examples and libraries, but it didnt work. my code:

private class HttpGetter extends AsyncTask<URL, Void, Void> {

    @Override
    protected Void doInBackground(URL... urls) {
        // TODO Auto-generated method stub
        StringBuilder builder = new StringBuilder();
        HttpClient client = new DefaultHttpClient();
        HttpGet httpGet = new HttpGet(String.valueOf(urls[0]));

        try {
            HttpResponse response = client.execute(httpGet);
            StatusLine statusLine = response.getStatusLine();
            int statusCode = statusLine.getStatusCode();
            if (statusCode == 200) {
                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);
                }
                Log.v("Getter", "Your data: " + builder.toString()); //response data
            } else {
                Log.e("Getter", "Failed to download file");
            }
        } catch (ClientProtocolException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }

        return null;
    }


}

You should execute the task like this new HttpGetter().execute(URL)

Note that AsyncTask can be executed only once.
