Google Play Services / Firebase / ML Kit for Xamarin.Android

Xamarin creates and maintains Xamarin.Android bindings for Google Play Services, Firebase, and ML Kit.

What is Google Play Services / Firebase / ML Kit

Google Play Services, Firebase, and ML Kit (GPS/FB/ML) are a set of libraries that allow Android apps to take advantage of Google APIs and services.

Binding Policies

  • This repository binds over 140 GPS/FB/ML libraries that are published to The full package list can be found in config.json.
  • GPS/FB/ML Java artifacts come from Google's Maven Respository.
  • Google's release notes for GPS/FB/ML libraries are available here.
  • The major/minor/patch version numbers are the GPS/FB library version prefixed with a 1. For example, the NuGet Xamarin.GooglePlayServices.Maps 117.0.1 binds version 17.0.1 of the GPS library
    • The revision version number is used when a new NuGet needs to be built but the GPS/FB/ML library has not been updated.
  • We endeavor to release updated NuGets within a month after new GPS/FB/ML releases, however large changes occasionally require more time.
  • In general, we do not bind pre-release libraries. As their API is not stable yet, it results in too much rework.
