Answer 1

There is an networkChange event in the NetworkInfo class: http://help.adobe.com/en_US/FlashPlatform/reference/actionscript/3/flash/net/NetworkInfo.html

Answer 2

Hi I have used a following code successfully.

You only have to import: import air.net.URLMonitor;

protected function init():void
        {
            // Center main AIR app window on the screen
            nativeWindow.x = (Capabilities.screenResolutionX - nativeWindow.width) / 2;
            nativeWindow.y = (Capabilities.screenResolutionY - nativeWindow.height) / 2;
            // Detects a general change in network status
            NativeApplication.nativeApplication.addEventListener(Event.NETWORK_CHANGE,onNetworkChange);
        }

        //Checking for network connectivity
        protected function onNetworkChange(e:Event):void
        {
        //  Alert.show("Your Network State changed", "INFO");
            monitor = new URLMonitor(new URLRequest('http://www.adobe.com'));
            monitor.addEventListener(StatusEvent.STATUS, netConnectivity);
            monitor.start();
        }

        protected function netConnectivity(e:StatusEvent):void 
        {
            if(monitor.available)
            {
                Alert.show("Status change. You are connected to the internet", "INFO");
            }
            else
            {
                Alert.show("Status change. You are not connected to the internet", "INFO");
            }

            monitor.stop();
        }

Answer 3

Do you have these classes available to your app:

import air.net.*;

i.e. a directory named 'air' sat next to your .fla file.

Answer 4

You need to add the aircore.swc

Go to File->ActionScript Settings

On the Library Path tab, click the + icon (Add New Path) and then click the Flash icon (Browse To SWC).

You then need to browse to the location where Flash CS5 is installed and go to AIK2.5/frameworks/libs/air/ and select the aircore.swc

Answer 5

In {Flash_CS5_installation_path}/AIR{air_version}/frameworks/libs/air you can find *.swc files , which you need to include in your application. About 'How to include' read here.
