The way I do it, is to keep an eye in the package name of lucky patcher, in case they change it. So at runtime I check if it is installed, and I simply do not allow to use my app if this one is actually installed on the phone, even if they purchased the app. I warn the user and kill my app. So he will have to find another way to crack it. The worse I can get is that he has to buy my app and will sure put 1 bad review. But honestly, I prefer 1 bad review from a hacker than 1000 pirated copies a day.
