Android Code Snippet Google Play Game Services Installed?

In order to avoid the popup that says, "app won't run without Play Games service," I discovered a method for checking to see if it is installed. If not, you can skip your code relating to Play Games services.

Dim pm As PackageManager
Dim installed =pm.GetInstalledPackages.IndexOf("")>-1 As Boolean
If installed Then
' code to execute if installed
End If
