Creating custom taskbar icon in Flex application

I'm trying to create custom icons for my taskbar/desktop icons in my Flex WindowedApplication. So far, I've edi开发者_开发百科ted my -app.xml file to include the following:

icons/t_16.png icons/t_32.png icons/t_48.png icons/t_128.png

When the application is run, however, the default flex/air icon is still showing. I have my systemChrome set to standard, and transparent to false, not that they have any relevance to this.

Any ideas?

Have you actually built a release version and installed your air app, or is just the debug version ?

UPDATE:

You have to deploy a release version before the custom application icon will be enabled.
