IO Exception on invoking execute() method of HttpGet class

Question

Why I'm getting IOException in this peace of code? Thanks.

HttpClient httpclient = new DefaultHttpClient();
HttpGet httpget = new HttpGet("http://www.google.com/");
HttpResponse response;
    try {
        response = httpclient.execute(httpget);
    } catch (ClientProtocolException e) {
         Toast.makeText(this, "ClientProtocolEx", Toast.LENGTH_LONG).show();
         e.printStackTrace();
    } catch (IOException e) {
         Toast.makeText(this, "IOEx", Toast.LENGTH_LONG).show();
         e.printStackTrace();
    }

Exception:

what about giving us the stacktrace and the message of the exception? — Bozho

HttpEntity entity = response.getEntity();
String s = entity.toString();

Try adding this after response = httpclient.execute(httpget);

And also if this doesn't help, you must edit your manifest xml file and give your application INTERNET uses permission.

Thanks for the hint about manifest.xml - that was a root of the problem. As for your first statement - that couldn't possible help because method execution is stopped on the line where it happened and proceed in catch block. Thanks a lot.
