Sample Adobe AIR Android application class that handles incoming NFC intent data.

NFCDataHandling.as

package
{
    import flash.desktop.NativeApplication;
    import flash.events.InvokeEvent;

    public class NFCDataHandling extends Sprite
    {
        /**
        * Constructor
        */		
        public function NFCDataHandling()
        {
            NativeApplication.nativeApplication.addEventListener(InvokeEvent.INVOKE, onApplicationInvoke, false, 0, true);
        }
        
        protected function onApplicationInvoke(event:InvokeEvent):void
        {
            //If there is any intent data that was passed to the app - in this case, say an NFC URI - there
            //will be data in event.arguments. It will be an array, and the first item will be
            //the full URI string, i.e. {SCHEME}://{HOST}/{ARGS}
        }
    }
}
