Error: Application not installed, when trying to install Google Play Services APK I'm using XOLO A500 running Android 4.0.4. Initially, it was showing this error: 



Then I tried installing Google Play Services through APK file(that was solution on many sites), but I am getting the error "Can't install Google play services":



I rooted the  device, and  accidentally, my friend deleted it.

Download recent version of Google Play Services app's APK
