Bluestacks is full of Ads and junk. But it has actual additions to make it work with a keyboard. Waydroid wasnt able to register multi-input for me, which makes basically any game unplayable.
But the android app smart autoclicker is the perfect replacement for bluestacks things.
Yes. Built into Android Studio. Has existed for at least five years. However I only ever used it with the apps I was developing and never even considered using it as a means to launch outside apps. That probably would have been painful.
someone did that before microsoft had even released WSA but I don't see anything about people doing it recently. probably someone is working on it right now though, given this news.
