I've found myself occasionally wishing for a Codespace that was ready-to-go for Android development.

Is there an appetite for an Android Codespace? Ideally the Codespace would

1. Get the NDK/SDK set up
2. Get an emulator image
3. Do a build of -rc release -s mono+libs
4. Start an emulator with postStartCommand so the emulator is running when the Codespace starts.

If anyone else thinks this is a good idea, I'm happy to work on a devcontainer.json+Dockerfile for this, but would probably need someone with Administrative permissions to set up prebuilds, assuming we even want a prebuild of this.
