Many of you have found that older apks packaged with an older version of our AIR SDK do not work with the newest version of the AIR Runtime we just dropped to this prerelease (6/4/2010). Specifically, a black screen is shown instead of the application.
Please make sure you package your application with the latest AIR SDK (6/4/2010) when running your application on a device with the latest 6/4/2010 AIR Runtime.
We are currently making significant changes to the AIR Android SDK and Runtime, so this may happen occasionally with our prerelease drops. To be sure that your app works properly, please make sure that your apk is packaged with an AIR SDK that is included in the same drop as your target AIR Runtime.

If you've signed up for the AIR for Android prerelease program, please use the prerelease forum for discussing Android issues.
can you please show a link for that?
