如果没有连接，我想用消息处理此错误我试图在创建完成时为互联网连接设置条件

            protected function view1_creationCompleteHandler(event:FlexEvent):void
        {
            monitor = new URLMonitor(new URLRequest('http://www.adobe.com'));
            monitor.addEventListener(StatusEvent.STATUS, announceStatus);
            monitor.start();
        }

        public function announceStatus(e:StatusEvent):void {
            trace("Status change. Current status: " + monitor.available);
            (new AlertMsg()).open(this, false) ;
        }

但如果没有连接则无法达到

注意：我的目标是android
