Google is developing a Terminal app for Android that’ll let you run Linux apps. It’ll download and run Debian in a VM for you.
…
Engineers at Google started work on a new Terminal app for Android a couple of weeks ago. This Terminal app is part of the Android Virtualization Framework (AVF) and contains a WebView that connects to a Linux virtual machine via a local IP address, allowing you to run Linux commands from the Android host. Initially, you had to manually enable this Terminal app using a shell command and then configure the Linux VM yourself. However, in recent days, Google began work on integrating the Terminal app into Android as well as turning it into an all-in-one app for running a Linux distro in a VM.
…
Google is still working on improving the Terminal app as well as AVF before shipping this feature. AVF already supports graphics and some input options, but it’s preparing to add support for backing up and restoring snapshots, nested virtualization, and devices with an x86_64 architecture. It’s also preparing to add some settings pages to the Terminal app, which is pretty barebones right now apart from a menu to copy the IP address and stop the existing VM instance. The settings pages will let you resize the disk, configure port forwarding, and potentially recover partitions.

If you’re wondering why you’d want to run Linux apps on Android, then this feature is probably not for you. Google added Linux support to Chrome OS so developers with Chromebooks can run Linux apps that are useful for development. For example, Linux support on Chrome OS allows developers to run the Linux version of Android Studio, the recommended IDE for Android app development, on Chromebooks. It also lets them run Linux command line tools safely and securely in a container.
Steam?
No, not unless you have an x86 Android device. While this will run Linux apps, it will be limited to the CPU architecture. Unless there is a x86 to ARM translation layer on Linux that I’m not aware of?
box86/box64, and there’s also FEX-emu which is used by the Asahi Linux project (Linux on Apple Silicon macbooks).

It appears Valve is working on Proton for arm64, I was wondering if this is to attend the mobile market, a new Index or maybe a smaller Steam Deck.
You can use QEMU’s usermode emulation to transparently run ARM binaries with binfmt_misc on x86.
Steam requires it to be installed in an x86 environment, whether natively, or through emulation (and most x86 emulation has significant overhead and imperfections)
But java applications should run natively if you supply an appropriate build of java. I have an arm VPS that I’ve hosted several Minecraft servers on without any problems (other than those I created myself) and I also learned by accident that Microsoft’s builds of OpenJDK actually work for (at least some) Minecraft versions that they aren’t supposed to, so I have to wonder if that’s a happy accident or intentional work by Microsoft
