Can App Ops run on 4.4.4? I have installed and tried several of the "App Ops" starter apps from the Google Play store. When I run any of them, a dialog pops up saying "Unfortunately, Settings has stopped." and my only choice is to tap "OK". So, I still have not been able to get to the App Ops settings.

However, this app claims to work on 4.4.4. 

I am running on the stock Moto G (2nd gen), Android version 4.4.4. Not rooted.

Are unrooted 4.4.4 users generally restricted from running App Ops or is there something wrong with my setup? If it is as simple as getting another app to run App Ops for me, can someone point to one that works in 4.4.4 without the error?
App Ops can be activated using Xposed Module, but for that you need to root your device. And an alternative to App Ops is XPrivacy.
