How would that look? I'm calling my class method as soon as the
applicationComplete event occurs. Everything else is in Actionscript,
the only MXML is this:
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml
<http://www.adobe.com/2006/mxml> "
layout="absolute"
applicationComplete="EntryClass.main()">
</mx:Application>

Even though the API says addChild takes DisplayObject, we can't
override function signatures. The rules in Flex are:
Navigator can only take Containers
Containers can only take IUIComponents
UIComponents can take anything.
So put in a UIComponent tag and put the test sprite in there.

The first error says you need the TestSprite class to be defined
like:
public class TestSprite extends Sprite
The second error I initially thought was because the application
addChild takes a UICompoent, but according to the help docs what
you
have 'should' work. I would try casting it as a DisplayObject
although
this probably isn't the correct way to fix it.
mxmlApp.addChild(testSprite as DisplayObject);
