private boolean IsWifiConnected() {
     ConnectivityManager connManager = (ConnectivityManager)getSystemService(Context.CONNECTIVITY_SERVICE);
     //NetworkInfo state_3g = connManager.getNetworkInfo(ConnectivityManager.TYPE_MOBILE);
     NetworkInfo state_wifi = connManager.getNetworkInfo(ConnectivityManager.TYPE_WIFI);
    
     if(state_wifi.isConnected() == true)
      return true;    
     else
      return false;
    
     //return state_3g.isConnected() || state_wifi.isConnected();
 }
