I've answered this to others as well on android-security, but basically, if you're thinking that using this licensing service will absolutely stop your user from being able to reverse engineer your app, you're plain wrong. You can always consider a hacked rom that lets you inspect the executable code at runtime, after it's been decrypted. If you have any really IP secure stuff that *absolutely can't* be distributed, you better offload that operation to a web service or something. Using a licensing service like LVL can help prevent someone just taking the apk off the phone and giving it to their friends, but it can't stop someone from reverse engineering your app if they *really want to*. So basically, don't just use LVL and assume you're really secure, that's not how it works. Piracy is a continuum, using LVL will definitely thwart a lot of the cases, and make it much more work to break your app, but it will still be possible. Basically, if you can *run* the app, you can *copy* the app...
