I noticed that Proguard is able to produce obfuscated code which makes Java Decompiler <http://java.decompiler.free.fr/> crash. It's a reasonable step to obfuscate any app (also free ones) in order to make it harder to figure out where to apply these changes or how to crack them.
More advanced protection steps are described here<http://www.google.com/events/io/2011/sessions/evading-pirates-and-stopping-vampires-using-license-verification-library-in-app-billing-and-app-engine.html>. To sum it up: on top of code-obfuscation you need to add hidden self-integrity checks to your app that try to validate the package signature.
