Google play services won't run unless you update Google play services I am constantly getting a notification about every 1 or 5 minutes since I had updated the Google Play Services app. It's a very strange type of notification. It says "Google Play Services won't run unless you update Google Play Services". See the screenshot below :


What is the cause of this problem and how to fix it ?
I have solved the problem myself, like this :
Previously, I had updated Google Play Services from an APK file. So, this time, instead of updating Google Play Services from an APK file, I had updated it from the Play Store, and the notification went away.
So, for some reason, updating the app from an APK file was causing the problem.
