I don't understand what this would be useful for. The Linux terminal app on Android (check Developer settings if you want it) already exists and it uses hardware accelerated virtualization, while this uses QEMU with TCG. The Linux terminal app also supports running a DE (No VNC - as in no VNC, not NoVNC - required!), has full shell, full root, all the features of Podroid, and hell, you could even swap out the terminal if you wanted to. The only advantage to this seems that it supports Android 14, 15, and 16. Am I missing something, or does this have no purpose?

My understanding is that the integrated linux terminal is not supported on all processors like snapdragon ones and also is not available on all manufactures like Samsung. Therefore this approach covers a much bigger audience.
microtonal 2 days ago [-]
I think it was only available on Google Pixel until recently. As far as I understand, some Samsung Exynos devices support it (e.g. Z Flip 7, non-US S26 with Exynos), but not Snapdragon devices, which don't seem to support non-protected VMs yet:
Error code: java.lang.UnsupportedOperationException: Non-protected VMs are not supported on this device

I can find it on my S25fe with exynos android 16/oneui 8.0 if I search for it in the setting but is greyed out. I wait for 8.5 to see if it is enabled then and is the only time I'm happy to have an exynos device!

This. Also, for phones that don't support Android virtualization, there's a user-space hack, part of Termux upstream, that allows for root-less chroots via LD_PRELOAD: https://wiki.termux.com/wiki/PRoot.
systemd won't boot with this (needs to be PID 1), but a lot of software will work just fine and there's nearly zero emulation overhead.
yjftsjthsd-h 1 days ago [-]
I don't think it uses LD_PRELOAD, it uses ptrace to intercept system calls (hence the name). Unfortunately this does have performance overhead, although I've never bothered to measure it. Actually that would be an interesting thing to benchmark.
m132 21 hours ago [-]
My bad, I must have confused it with something else. Yes, it uses ptrace; there definitely is some overhead around system calls, but that still should be better than running atop a full-scale CPU emulator. That being said, I haven't benchmarked it myself, just remember it being pretty snappy.
Thanks for your correction!

Android's terminal app is really slow and takes some time to boot comparing to Termux.
Also, the Terminal app is essentially a webview (as I understand, the reason is architectural).

The Linux terminal app on Android reddits are full of reports of instability. It is far from being useful as far as I understand. I had so much hope for this being a good way to use my phone as a portal for development, but it's a dud. At least we have termux and proot.
dredmorbius 1 days ago [-]
Termux itself is a red-headed step-child on Android, with current releases installable only from F-Droid, and quite possibly subject to further restrictions in future.
Mind: Termux is the only thing on Android which has not precisely sucked in my own 15+ years' experience with the platform. It remains both crippled and emperiled by the OS and Google.
My own interests lie more in the ability to run Android emulated under Linux, and switching from phone / tablet devices to a small form-factor laptop (Framework 12 or 13 most likely) for on-the-go computing.

Not everyone owns one of the limited range of devices that Linux Terminal is available for. For example, no Snapdragon chips currently in use support the "non-protected" virtual machines required by the Android Virtualization Framework. Also, it doesn't jive with Samsung Knox, so the few Samsung devices that this might work on (mostly international models with Exynos chips) will likely not be supported.

- A math mini CAS with Esc-x calc RET
- Esc-x package-install RET malyon, get some nice ZMachine text adventures at IFDB
- Elisp environment+cl-lib can do a lot
- Esc-x package-install jabber, Esc-x jabber. Chat with cool people at XMPP servers.

- LSP integration it's possible

I tried Emacs, but realised I need NixOS to get the packages I depend on like git to download my config. I can't use stock emacs. There's a trick to get Emacs and termux to share packages, but not for nix-on-droid :/
I think this is great, I've wanted some sort of docker on android system and this does the job quite nicely all wrapped up in an apk. So there is definitely space for this in the current ecosystem. The new terminal built into android crashes whenever I try booting it up.

The latest stable release of Waydroid is from little over a month ago. The Android image it uses by default is based on Android 13, which is fresh enough to do its job.
Why wouldn't it? All you need is a binder device for Android IPC and root access to launch Waydroid. It should work perfectly fine when installed and used with Wayland.

The QEMU TCG approach makes sense for isolation, but I'm curious about the traffic routing story. Does each container get its own network namespace, or does all traffic still go through Android's network stack? The latter would mean carrier-level DPI still sees everything the container sends — which matters a lot depending on what you're running.

X86 builds of Android are stuck at many generations back of the OS. Running Android in a VM on X86 is basically dead AFAIK. :(

I'm actually optimistic that this will improve. Google has apparently been working on replacing Chrome OS with android, which I have pretty strong opinions on but the upside is that if they want to go that route they're going to have to make Android officially work well on x86, at which point there's no reason that eg. LineageOS wouldn't be expected to follow suit.

People are holding it wrong.
Instead of embracing the Java/Kotlin userspace alongside C and C++ on the NDK, with the official APIs, they try to subvert into GNU/Linux.
First of all bionic isn't glibc, secondly the Linux kernel is only a matter of convenience for Google, which they could in theory replace by something else, while keeping the Java/Kotlin and the NDK C/C++ APIs.
Which is exactly termux isn't without issues on modern Android versions, not much different than using cygwin/mingw on Windows.

Android kernel has the relevant kernel parameters disabled. It is entirely possible to run containers directly on android, but it requires enabled the relevant parameter (iirc no recompilation need, just a cmdline change). But this of course requires root.

I find it somewhat amusing that it uses QEMU to emulate Linux in order to create a container with restricted permissions, even though it is already running on Linux with restricted permissions. I get the point while it is designed that way, but still funny.
Error code: java.lang.UnsupportedOperationException: Non-protected VMs are not supported on this device
