Doing a apktool d and subsequent apktool b on a specific app results in a base.apk that is about half the size of the original (39M vs 61M). Hence, when the app is launched I get a ClassNotFoundException. apktool doesnt show any errors in decompilation or compilation either.

I assume Dropbox app based on stacktrace? Or can you link me to exact version/app you are referring?

I can share the apks if needed.

Any news?

I downloaded the application and was surprised to find it over 200mb - for a remote...for a car. Thats about all the news at the moment.

Yeah, it's enormous. But I'll be interested to see if the size reduces significantly when you assemble it again with apktool. I suspect it strips away quite a bit by mistake.
