con.getInputStream() throw exception in Android project, how to fix?

Question

con.getInputStream() throw exception, when the code running on android, but when copy the code to regular java project it is working,
The thrown object e contain "detailMessage = Permission denied". my code::

            public static HttpData get(String sUrl) {
                HttpData ret = new HttpData();
                String str;
                StringBuffer buff = new StringBuffer();
                try {
                        URL url = new URL(sUrl);
                        URLConnection con = url.openConnection();
                        BufferedReader in = new BufferedReader(new InputStreamReader(con.getInputStream()));
                        while ((str = in.readLine()) != null) {
                                buff.append(str);
                        }
                        ret.content = buff.toString();

                        //get headers
                        Map<String, List<String>> headers = con.getHeaderFields();
                        Set<Entry<String, List<String>>> hKeys = headers.entrySet();
                        for (Iterator<Entry<String, List<String>>> i = hKeys.iterator(); i.hasNext();) {
                                Entry<String, List<String>> m = i.next();

                                Log.w("HEADER_KEY", m.getKey() + "");
                                ret.headers.put(m.getKey(), m.getValue().toString());
                                if (m.getKey().equals("set-cookie"))
                                ret.cookies.put(m.getKey(), m.getValue().toString());
                        }
                } catch (Exception e) {
                        Log.e("HttpRequest", e.toString());
                }
                return ret;
        }

Make sure you get <uses-permission android:name="android.permission.INTERNET"/> and not <permission android:name="android.permission.INTERNET"/>! That bit me for an hour...
