How do you integrate the new Google Sign-In on a Xamarin.Android app?
I am attempting to follow Google's instructions on how to add the new Google Sign-In (not the old Google+ Sign-In) to my Xamarin.Android app. For the life of me, I cannot find the correct Google Play Services NuGet package or Xamarin component that supports the new sign-in system. When I add the following code to the activity, I get "The type or namespace 'GoogleSignInOptions' could not be found. Are you missing an assembly reference?" build error. // Configure sign-in to request the user's ID, email address, and basic // profile. ID and basic profile are included in DEFAULT_SIGN_IN.
