Support for ARM host builds of Android targets?

[Sintrastes]

The documentation for obelisk (which I believe is using reflex-platform for android build support -- hence why I'm posting that here. If that's incorrect, I can move this issue over there) mentions that Android builds are currently only supported on Linux.

I am currently running an Ubuntu 20.04.4 (ARM64 edition) LTS virtual machine on my M1 Macbook Pro in an attempt to get around that restriction, but it appears that additionally, Android builds are not supported on ARM64 Linux either.

When I run nix-build -A android.frontend -o result-android in my project, I just get:

error: Android builds are not supported on this platform.

Has anyone actually tried and confirm that Android builds are not working on ARM64 linux yet? If so, and it is indeed not working on that platform, what would it take for builds to be supported?

Google doesn't provide binary NDK releases for aarch64-linux which makes this significantly harder. It's possible to build an android app without the NDK (using the non-prebuilt crossSystem in nixpkgs for android) but gradle will fail because it refuses to copy versioned libraries.

There is also probably another chunk of issues that I haven't ran into yet, it's a big chunk of unexplored work.
