Unity is doing  a big role in android gaming world.It is  good for developers since it is really powerful and friendly for beginner.But protecting developers is a big responsibility for unity itself.So here comes what the title say.I have seen a lot of new unity games on google play that LP can not hack,even they do not do online checks.In-App billing emulation doesn't do any magic.I can see a lot temp directories in /sdcard/Android/data//Unity/UnityPurchasing,It's easy to see that Unity is definitely using new method to check IAP.But LP is still stuck at the very old way.
I'm not here to complaints,but to says the truth.So I'll stop at here.If anyone can leave the appname that has the problem,i think it will be useful if some cracker want to look into it.
