Wow it can force psvita as well. I wanted to make an android version of my game too, but it's been a rough few months and I have an old phone with android 7, gamemaker doesn't support that. As soon as I can, I'll try to make an official android version. I have to work on the Linux version too, I had to install linux on an old laptop to make it and I haven't properly debugged it xd. But I'll get to it eventually. It's cool you can play it on your handheld.
