You complain about Android Fragmentation?

Hang on, you're telling me that you installed a new beta version of the operating system, went into an app that you develop that uses part of the SDK that was totally and completely revamped and updated today, and it didn't work?!

Pardon my french, but does a bear in the woods?

Of course it isn't going to work right out of the box, that's why you're the developer and this is a beta.

Android may be designed to work in a way so that hardware and software versions don't matter, but it doesn't always and it doesn't always do it out of the box either.
