Show Notifications in Air - Flash Builder 4.6

Hi, I'm new into Flash Builder mobile apps development.

I just downloaded the latest release of Flash Builder, the 4.6.

I read in this Adobe's article, that with this version I can add "Notifications" to my apps.

I tried to, but all my experiments failed.

Here's a quick personal video illustrating all my steps, and coding errors, please, whatch it:

(It's very, very short, just the time to write some lines of code)

I think my error is simple to solve... but I'm a NewBie and I don't know very much this programming IDE.

Thanks everybody for any help.

Have a nice day

Brandon

WOW!

I'm seeing now that my video's quality is very low... here's the code I wrote:

// Here I want to declare my personal Notification Variable, as said in Adobe's Tutorial
private var myNotification:NotificationManager;
  // I saw that NOTIFICATION MANGER does not exist in my code library... but I tried pasting Adobe's one...
  // as you can see from this video... the compiler gives me coding error..
  
  
  // CONCLUSION... WHAT CAN I DO ???
  // THANKS TO ALL !!!
  // Bye  🙂
   
protected function button1_clickHandler(event:MouseEvent):void
{
// Here I'll paste Adobe's code to create a new Notification for my first Flash Builder Mobile App...
//
// CODE...
//
}

Thanks again
