Microsoft creates and maintains .NET for Android bindings for many of Google's Java/Kotlin Android libraries and their required third-party dependency libraries, such as:

• AndroidX (Google Release Notes)
• Google Play Services (Google Release Notes)
• Firebase (Google Release Notes)
• ML Kit (Google Release Notes)

Note that support for Xamarin.Android ended on May 1st, 2024. New versions of these packages will only support .NET for Android.

• This repository binds over 600 Android libraries that are published to NuGet.org. The full package list can be found in config.json.
• Most Google Java/Kotlin artifacts and some dependencies come from Google's Maven Respository.
• Additional dependencies come from Maven/Sonatype Central.
• The major/minor/patch version numbers mirror the bound Android library version. For example, the NuGet Xamarin.AndroidX.Core 1.3.2.1 binds version 1.3.2 of the AndroidX library androidx.core:core.
  • Note that some packages like GooglePlayServices* may prepend a "1" to the version number. For example, the NuGet Xamarin.GooglePlayServices.Base 118.5.0 binds version 18.5.0 of the Java library.
  • Version and Java artifact information can be found in the NuGet readme (example).
  • The revision version number is used when a new NuGet needs to be built but the Android library has not been updated.
• We endeavor to release updated NuGets within a few weeks after new Android 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. Additionally, it can result in stable NuGet packages depending on unstable NuGet packages.

Note that these packages are largely just autogenerated bindings around Google's Android libraries. As such, our support is limited to issues caused by our bindings. For tutorials/samples/support using the libraries themselves, please refer to Google's documentation.
