Android:HttpClient does not run in Android 4.0 API

Question

I have written the code it works on Android 2.2 API but it does not work on Android 4.0

 String url = textUrl.getText().toString();
     HttpClient client = new DefaultHttpClient();
     HttpGet  request = new HttpGet(url);
     try
     {
        HttpResponse response = client.execute(request);
        textResult.setText(HttpHelper.request(response));
     }
     catch (Exception e) {
        // TODO: handle exception
         textResult.setText("Failed");
    }

Answer 1

Internet communication must run in a separate thread.

Use AsyncTask to simplify this.

You can read more about threads in Android here

EDIT: If you really want to access the internet on the main thread, you can allow it in the onCreate() method with the following code:

StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitNetwork().build();
StrictMode.setThreadPolicy(policy);

However, I really wouldn't recommend this approach.
