java.net.UnknownHostException: Unable to resolve host "www.google.com"

I'm trying to detect if there is actually an internet connection and websites are reachable. I have a broadcast receiver that runs the following method on receive:

  public boolean hasInternetNow() {
           Thread checkinternet = new Thread(new Runnable() {
               @Override
               public void run() {
                 try {
                      try {
                            ConnectivityManager cm = (ConnectivityManager) myContext.getSystemService(Context.CONNECTIVITY_SERVICE); 
                            if (cm.getActiveNetworkInfo().isConnectedOrConnecting()) {
                                URL url = new URL("http://www.google.com");
                                HttpURLConnection urlc = (HttpURLConnection) url .openConnection();
                                urlc.setRequestProperty("User-Agent", "test");
                                urlc.setRequestProperty("Connection", "close"); 
                                urlc.setConnectTimeout(1000); // mTimeout is in seconds
                                urlc.connect();
                                if (urlc.getResponseCode() == 200) {
                                    setinternetDetected(true);
                                     } else {
                                    setinternetDetected(false);
                                  }
                            }
                        } catch (IOException e) {
                            e.printStackTrace();
                            setinternetDetected(false);
                        } catch (NullPointerException e){
                            e.printStackTrace();
                            setinternetDetected(false);
                        }


                 } catch (Exception e) {
                   e.getLocalizedMessage();
                   setinternetDetected(false);
                 }
               }
             });
            checkinternet.start();
            return internetDetected();
        }

While connected to the Wifi and google is reachable through the internet app, I get the following error:

What am I missing here?

This method easily does the same:

public boolean isInternetAvailable() {
        try {
            InetAddress ipAddr = InetAddress.getByName("google.com"); //You can replace it with your name

            if (ipAddr.equals("")) {
                return false;
            } else {
                return true;
            }

        } catch (Exception e) {
            return false;
        }

    }
