The developer of xprivacy already debugged this issue and came to the conclusion that the problem is in the way you implemented your verification. Because even with Poweramp being fully unrestricted it still gave that error for no reason whatsoever. Xprivacy just hooked into a function and your app didn't like it even when it was not being restricted. I don't see how this is xprivacy's fault. And its kind of on your side, because out of the 87 premium apps I have purchased including those that use an unlocker, in-app purchases, or single apk, none of them have an issue with xprivacy when unrestricted, except yours. And I know I'm not the only one seeing this pattern. I however, thank you for altering the way you check the license. The build you posted worked fine with no license problems.
