How to protect app from patching

I am making paid application and I check license using Google LVL library. But some patchers (like Lucky Patcher) can remove that license check. How can I protect it from patching or in what way I can make a remote server from license check?

If your app uses data from a server, you can send the licence number with the requests and you can deny the answer when the licence is invalid.

Since anyone has access to your apk you can't prevent patching. Although you can make it way more difficult is several ways:

  • Code obfuscation - ProGuard can do it for you, makes code barely human readable
  • Add additional offline checks - you can access app signature using PackageManager and compare with yours. Nobody can fake your signature + code obfuscation will help to hide that couple of lines of code
