Indeed, Al's protection scheme works. I have just 2 issues with it: 1. Key length should be configurable, depending on the country at which the app would be used, right? AFAIK strong key encryption is not allowed outside the US (or at least in some countries), but I might be wrong.
2. I've seen some links on the web where people reverse engineer the dex format (probably not fully). I know it's closed source (or is it?) but if someone reverse engineers it fully then there's no protection whatsoever -- I'll just get the java code, and even if it's obfuscated I can remove the single "if" statement in the protection code, recompile, sign with my key and redistribute the new .apk for free. I hope this won't happen, but who knows.
