Easiest method to check network status on iPad with Adobe Air - actionscript-3

Question

I would like to check the network status on the iPad with Adobe Air, at this moment i am checking by sending a URLREQUEST to Google.com. Is there any other better way to monitor the network status, and know if there is a connection or connection have been dropped. Thanks for any suggestion.

Tricky part here we are not ping some interval times. so we use
NativeApplication.nativeApplication.addEventListener(Event.NETWORK_CHANGE, onNetwork_ChangeHandler);
It will trigger when ever change net status change so performance wise also good.
Because Ping is very costly operation.So call start() URLMontior after network changed triggered then we call stop().
package com.abc.net
{
import air.net.URLMonitor;
import flash.desktop.NativeApplication;
import flash.events.Event;
import flash.events.EventDispatcher;
import flash.events.IEventDispatcher;
import flash.events.StatusEvent;
import flash.net.URLRequest;
[Event(name="networkStatusChanged", type="flash.events.Event")]
public class NetStatusMonitor extends EventDispatcher
{
private var urlMonitor:URLMonitor;
private var url:String;
public function KBNetStatusMonitor(url:String = 'http://www.adobe.com')
{
super();
this.url = url;
NativeApplication.nativeApplication.addEventListener(Event.NETWORK_CHANGE, onNetwork_ChangeHandler);
}
protected function onNetwork_ChangeHandler(event:Event):void
{
start();
}
public function start():void
{
urlMonitor = new URLMonitor(new URLRequest(url));
urlMonitor.addEventListener(StatusEvent.STATUS, onNetStatus_ChangeHandler);
if(!urlMonitor.running)
urlMonitor.start();
}
public function stop():void
{
if(urlMonitor.running)
urlMonitor.stop();
}
private function onNetStatus_ChangeHandler(event:StatusEvent):void
{
trace("event code " + event.code);
trace("event level " + event.level);
dispatchEvent(new NetStatusEvent(NetStatusEvent.NETWORK_STATUS_CHANGED,urlMonitor.available));
stop();
}
}
}
Event Class
package com.abc.net
{
import flash.events.Event;
public class NetStatusEvent extends Event
{
public static const NETWORK_STATUS_CHANGED:String = "networkStatusChanged";
public var status:Boolean;
public function NetStatusEvent(type:String, status:Boolean, bubbles:Boolean=false, cancelable:Boolean=false)
{
super(type, bubbles, cancelable);
this.status = status;
}
override public function clone():Event
{
return new NetStatusEvent(type, status, bubbles,cancelable);
}
}
}
Usage :
var netStatusMonitor:NetStatusMonitor = new NetStatusMonitor();
netStatusMonitor.addEventListener(NetStatusEvent.NETWORK_STATUS_CHANGED,function(event:NetStatusEvent):void {
statusCallBack.call(null,event.status);
});
netStatusMonitor.start();
