On 4.1+, paid apps are forward locked by default, which is implemented by splitting the APK in a public (in /data/app) and private part (in /data/app-asec). You are most probably calculating the hash of the public part only, hence the mismatch. If you have a rooted device you can verify by searching for you package name in /data/app-asec. -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
