			my_text.y=100;
			my_text.text = "Facebook API test";
			for (var i:int=0; i<2; i++) {
				my_button=new Button();
				addChild(my_button);
				my_button.label=button_labels[i];
				my_button.setSize(250,30);
				my_button.move(125, i*40+10);
				my_button.addEventListener(MouseEvent.CLICK, clickHandler);
			}
			session=new FacebookSessionUtil("83ccead57ece4086338470a75e13c5b1","1fff6abf608e90e70e1aad07798aa8e4",loaderInfo);
			session.addEventListener(FacebookEvent.CONNECT,onConnect);
			fbook=session.facebook;
		}
		function clickHandler(event:MouseEvent):void {
			switch (event.currentTarget.label) {
				case "Click here to login into Facebook" :
					onLogin();
					break;
				case "Click here once you logged in into Facebook" :
					onConfirmLogin();
					break;
			}
		}
		private function onLogin():void {
			session.login();
		}
		private function onConfirmLogin():void {
			session.validateLogin();
		}
		private function onConnect(e:FacebookEvent):void {
			var call:FacebookCall=fbook.post(new GetInfo([fbook.uid],[GetInfoFieldValues.ALL_VALUES]));
			call.addEventListener(FacebookEvent.COMPLETE,onGetInfo);
		}
		private function onGetInfo(e:FacebookEvent):void {
			user=(e.data as GetInfoData).userCollection.getItemAt(0) as FacebookUser;
			my_text.text="Hello "+user.first_name+" "+user.last_name+" born on "+user.birthday;
		}
 
	}
}

And this is the result:

As in the Flex example, you should click the 2nd button (the one saying “Click here once…”) only when you get “You may now close this window and return to the application.” message on your FB page.

I am really excited for this new API and I can’t wait to include it in a game.

    I integrated that code with a game. It works when I test it locally. but it doesnt work when I import to my server on the web. and it doesnt work when its implemented into facebook either.

    Apparently, this code was meant for external applications. What if I want to connect using flash from within facebook. As in the application sits within the facebook websites. So there really is no necessary reason to ask for user login

    Hi, thanks for the demo.

    When I click the “login to facebook” button in the demo above, I get this error from the debug player:

    u r getting error becoz u r clicking the 2nd button without getting user info. so there is a simple solution that write a single line
    i.e if(user!=null)
    {
    my_text.text=”dhsh”;
    }
    u will not get error.
