Android - trying to send POST request, throws an exception with no message

Simple code:

 String URL = "http://www.google.com";
                        try {
                            HttpClient httpClient = new DefaultHttpClient();
                            HttpPost httpPost = new HttpPost("http://xocircle.freeiz.com/index.php?id=425231&data=joiragiiij99newooo");
                            // Add your data
                            List<NameValuePair> nameValuePairList = new ArrayList<NameValuePair>(2);
                            httpPost.setEntity(new UrlEncodedFormEntity(nameValuePairList));
                            // execute HTTP post request
                            HttpResponse response = httpClient.execute(httpPost);
                        } catch(Exception ex) {
                            ex.printStackTrace();
                            Log.w("Error", ex.getMessage());
                        }

I run it on my android app and it crashes the app. Here's the message:

but I can't understand me.

I do have permissions and I do have internet connection.

Any help?

You can use

    new Thread(new Runnable()
    {
        @Override
        public void run()
        {

        }
    }).start();

and put your code inside the run method.

you have a android.os.NetworkOnMainThreadException , You need to perform all network operations inside a thread. So just wrap your code within a thread or an Async task and it should work.
