I am attempting to add Firebase based push notifications to my Xamarin Forms Android app as described in the developer guide on this site (I can't post links here yet).
However, as soon as I extend FirebaseMessagingService, I receive this error: "error: package com.google.firebase.messaging does not exist"
I have added the Xamarin-GooglePlayServices-Base and Xamarin-Firebase-Messaging Nuget packages as described in the tutorial and can see the references in my Visual Studio project. I have downloaded the example project that goes with the tutorial and it builds correctly as does a brand new project I created.
I have struggled with this for several days and am not sure what else I can try to resolve this issue. Any suggestions?
