How to add OnlineSubsystemGooglePlay", "AndroidAdvertising

Hello. I’m having problem with adding subsystemGooglePlay modules to the build.cs file. I have it working in one App on Google Play just fine with Ad Mob units showing perfectly but for some reason in my other projects the Build.cs file shows differntly and I don’t know how to add OnlineSubsystemGoolePlay and Advertising to it. Here is the Build.cs as from my non working project. All though if I do added in to the bracket it works great but once trying to uploaded to Google Play it shows error. Something about can’t find android name. So how do I add extension correctly so the APK passes trough the Gates of Google play.Thank for any kinda help.!!

using UnrealBuildTool;
PublicDependencyModuleNames.AddRange(new string[] { “Core”, “CoreUObject”, “Engine”, “InputCore” });

	PrivateDependencyModuleNames.AddRange(new string[] {  });

	// Uncomment if you are using Slate UI
	// PrivateDependencyModuleNames.AddRange(new string[] { "Slate", "SlateCore" });
	// Uncomment if you are using online features
	// PrivateDependencyModuleNames.Add("OnlineSubsystemGooglePlay", "AndroidAdvertising");

	// To include OnlineSubsystemSteam, add it to the plugins section in your uproject file with the Enabled attribute set to true


and also what does Uncomment if you are using features line mean. How do I Ucomment since I’m using online features such as of a Google Play services.
