I have installed Google play games but on android set up i get the following error: Android support library v4 not found at: C:/Users/*/AppData/Local/Android/sdk\extras\android\support\v7\appcompat\libs\android-support-v4.jar UnityEngine.Debug:LogError(Object) GooglePlayGames.GPGSUtil:CopySupportLibs() (at Assets/GooglePlayGames/Editor/GPGSUtil.cs:263) GooglePlayGames.GPGSAndroidSetupUI:PerformSetup(String, String, String) (at Assets/GooglePlayGames/Editor/GPGSAndroidSetupUI.cs:246) GooglePlayGames.GPGSAndroidSetupUI:PerformSetup(String, String, String, String) (at Assets/GooglePlayGames/Editor/GPGSAndroidSetupUI.cs:173) GooglePlayGames.GPGSAndroidSetupUI:DoSetup() (at Assets/GooglePlayGames/Editor/GPGSAndroidSetupUI.cs:102) GooglePlayGames.GPGSAndroidSetupUI:OnGUI() (at Assets/GooglePlayGames/Editor/GPGSAndroidSetupUI.cs:87) UnityEditor.HostView:OnGUI()
