Checking for network connectivity

You must Login before you can answer or comment on any questions.

I am using the code below in an attempt to notify users that they are not connected to a network. The problem is, my alertDialog box doesn't show up in the simulator when I test my app with no internet connectivity. Is there something missing from my code? I am using it in app.js

Full Code: http://pastie.org/1066272 

// check for network
if(!Titanium.Network.networkType == Titanium.Network.NETWORK_NONE){
     var alertDialog = Titanium.UI.createAlertDialog({
              title: 'WARNING!',
              message: 'Your device is not online.',
              buttonNames: ['OK']
            });
            alertDialog.show();
}

You got it backward if(Titanium.Network.networkType == Titanium.Network.NETWORK_NONE){ // that's no network connectivity. }

if(Titanium.Network.networkType != Titanium.Network.NETWORK_NONE){ anything but no connectivity }

I use this:

function check_network() {
    return Titanium.Network.online;
}
and works even in simulator ( I cut the airport )

I've always just loaded it onto my device and went in airport mode after the sync.

I'd love to know if it's possible in the simulator.

Actually now it is showing the alertDialog when I am connected to a network.

Any suggestions?

Tamas, I replaced your code with mine.

I am not getting an alert pop-up with your code, should I be seeing an alert that tells me I am not connected to a network? Thanks

Thanks Daniel, I found the fix with your solution. 

// check for network
if(Titanium.Network.networkType == Titanium.Network.NETWORK_NONE){
     var alertDialog = Titanium.UI.createAlertDialog({
              title: 'WARNING!',
              message: 'Your device is not online.',
              buttonNames: ['OK']
            });
            alertDialog.show();
}
