Internet do not work in Android 4

Question

I run the same code in Android 2.3.5 and in Android 4. But in the version 4, the internet seems to be not working. But when i check the browser in the phone it works.

HttpGet httpget = new HttpGet("http://www.blah.com/?"+paramString);
            try {
                HttpResponse response = httpclient.execute(httpget);
                HttpEntity entity = response.getEntity();
                //------- scrape data
                if (entity != null) {

and following is the error log

You're RIGHT! Android 4 broke the internet and Android 5 plans to break our highway and banking systems (also it will make anyone who uses it sterile!!). RUN FOR YOUR LIVES!!! — Yevgeny Simkin, Jun 06 '12 at 09:57

your main thread can't handle it so put it in AsyncTask.so you have to call http request in other thread

Android 4.0 Strictly forbids doing network operations on main thread. As Samir said perform network or any operations on non-UI which takes more than 5 seconds to execute.
