Add Android to Compatibility matrix

[marcprux]

An installable Swift 6.0.1 SDK Bundle for Android has recently been published at https://github.com/finagolfin/swift-android-sdk. Android would make a great addition to the build compatibility list. And unlike the windows support issue, this should be fairly straightforward to implement, since it can be added onto the Linux build. After running swift sdk install …, you'd simply need to compile with swift build --build-tests --swift-sdk aarch64-unknown-linux-android24.

That's a very interesting development, thanks for sharing! Are there any plans lands these SDKs somewhere under swiftlang at some point?

Yes, we will eventually be adding the Android SDK to the Swift community CI system with the hopes of graduating to a fully-supported platform. That's a long process (Windows is still not there after many years), but offering people insights into which projects are Android-compatible will be a good first step along this road.

I've set up a supplementary site at https://swift-everywhere.github.io that builds all the Linux-compatible packages for Android. 1,926 out of 3,321 packages (57%) are currently building successfully, which isn't a bad start. More will probably start passing once support for the Testing module is in place.

If anyone is interested in supporting Android in their packages, check that list to see if your repository is listed, and consider adding the swift-android-action to your CI workflows.
