I've tried to install Anbox a few times, but it hasn't worked so far...

[Crilum]

Wow, it's actually installing: snap install --devmode --edge anbox
I think what held me up last time was installing the required kernel modules, which I didn't do this time..

[sakagsakag]

https://docs.anbox.io/userguide/install_kernel_modules.html

i think we need compile kernel module ashmem and binder,
am i right?
but i dont have no compiling env.

Well, I tried installing the anbox-modules-dkms package from here, and got this:

and then I tried building the module itself (for which the source is in the deb), and got this:

It looks like the problem is that the kallsyms_lookup_name function got removed from linux, 5.7 and up...
anbox/anbox-modules#67

@Botspot This would be an amazing app for Pi-Apps, if it were somehow able to be installed (which I guess it could, but you'd have to build an old kernel to get it to work...).
Being able to install an Android compatibility layer would be awesome..

[theofficialgman]

downgrading the kernel is a hard NO.

however.. if you had looked, there is already a PR ongoing with the "dirty hack" for kernel >=5.7 support anbox/anbox-modules#76

hopefully the actual anbox developers step up and fix this

[theofficialgman]

also, with the piOS desktop now supporting wayland officially. waydroid may be an option as well https://waydro.id/#wdlinux

I'm not sure if their debian repo actually properly supports armhf/arm64 or not yet

[Crilum]

@theofficialgman Waydroid doesn't have the armhf version of python3-gbinder in their repos..

A couple of months ago I tried to get Waydroid working. I thought it may be possible to run it inside a nested Mutter window that was running in Wayland mode. It didn't work, and I think this was mutter's fault.

But I did get Waydroid to install, after a lot of attempts.
Here are my notes for the process:
