nullpointerexception - how to check internet connection in Google nexus 7 (android 4.2) -

I used to follow the code to check the Internet connection.

  public static boolean checkNetworkConnection (References) {boolean connected = true; ConnectivityManager connectivityManager = (ConnectivityManager) reference .getSystemService (Context.CONNECTIVITY_SERVICE); If (connectivityManager.getNetworkInfo (ConnectivityManager.TYPE_MOBILE) .getState () == android.net.NetworkInfo.State.CONNECTED || connectivityManager.getNetworkInfo (ConnectivityManager.TYPE_WIFI) .getState () == android.net.NetworkInfo.State.CONNECTED ) {Connected = true; } And connected = false; }   
 This code is working fine under the mobile but it is not working for Google Nexus 7 (Android 4.2).  
 When I test this code in Google Nexus 7 (Android 4.2). I got the error.

Connect or Orkknekting ()) return true; Second false return; }
