Handling back button on Android

[Robert Flesch]

I like the idea of the back button in Android, and I wanted to make use of it with in my app.

So I added a function

    function onKeyDown( event:KeyboardEvent ):Void
    {
        if ( BACK_BUTTON == event.keyCode )
            backHandler();
    }

It catches the "Back" key, but then goes on to minimize the app.
I tried calling "event.stopImmediatePropagation();"
but it has no effect. How can I stop this event at the current page with out it propagating?

any one know how to deal with this?

 Try onKeyUp instead of onKeyDown.

And readd event.stopImmediatePropagation();
