Question

I’m writing an application for Android. The application connects to a server to retrieve comments.
The code of interest is:

BufferedReader input = null;
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost("http://www.domain.com/personal_proj/directorydirectory/file.php");
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
HttpResponse response = httpclient.execute(httppost);
Log.i("TEST","after httpclient.execute()");
HttpEntity entity = response.getEntity();

I tested this code in HTC Wildfire, HTC Desire Z and it works. If this code is executed in Android 4.0+, it never reach the line

Log.i("TEST","after httpclient.execute()");

, the server never gets the request and it never throw an exception.

Any ideas?

Thanks to Charlie Collins i have noticed that i have not handled well the exception. The exception that i captured it’s android.os.NetworkOnMainThreadException. This means that i can’t perform a networking operation on the main thread (this is thrown for applications targeting 3.0+). Using AsyncTask worked for me.
