Unity3d Google Play Games plugin for Unity Crash com.google.android.gms.common.zze.zzi

I’m trying to link Google Play Services to my game for login and achivements. I followed instructions, installed and built the “Minimal Sample Scene” but when I run app and click authenticate App crashes and I get these messages from logcat:

I/Unity (30035): Building GPG services, implicitly attempts silent auth

Unity3d 5.3.2f1 - Google Play Games plugin for Unity 0.9.33

Thanks…

I think problem here is caused by AdMob plugin version 2.3.1, I updated Admob to 3.0.1, problem is solved.

Not sure this was the issue, but according to the Android docs, the method that cannot be found was added in API level 21:

What device are you using to test this ? and what is the Android version it is running?

Thanks…
