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

Microsoft creates and maintains .NET for Android bindings for many of Google's Google Play Services, Firebase, and ML Kit libraries.

Support for Xamarin.Android ended on May 1st, 2024. New versions of these packages will not support Xamarin.Android.

What is Google Play Services / Firebase / ML Kit

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

Binding Policies

• This repository binds over 200 GPS/FB/MLKit libraries that are published to NuGet.org. The full package list can be found in config.json.
• GPS/FB/MLKit Java artifacts and some dependencies come from Google's Maven Respository.
• Additional dependencies come from Maven/Sonatype Central.
• Google's release notes for GPS/FB/MLKit libraries are available here.
• The major/minor/patch version numbers are the GPS/FB/MLKit 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 com.google.android.gms:play-services-maps.
  • The revision version number is used when a new NuGet needs to be built but the GPS/FB/MLKit library has not been updated.
• We endeavor to release updated NuGets within a month after new GPS/FB/MLKit 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.
