This is the code that i use to make the request:

    HttpClient httpclient = new DefaultHttpClient();
    HttpPost httppost = new HttpPost(new Connection().Url()+":"+new Connection().Port()+"/Punche/ByName");

    try {
        // Add your data
        List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(1);
        nameValuePairs.add(new BasicNameValuePair("name", "n"));
        httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));

        // Execute HTTP Post Request
        HttpResponse response = httpclient.execute(httppost);

    } catch (ClientProtocolException e) {
        // TODO Auto-generated catch block
    } catch (IOException e) {
        // TODO Auto-generated catch block
    }

Thanks for the help.

It looks like you're running network code on your ui thread. Make sure that all your code runs on a different thread than the ui thread. Look here for an example on the correct way to implement this.

You can't do network requests on the main thread. You must do it on an AsyncTask or Thread.
