I tried Waydroid on Arch and its amazing. It runs Android apps flawlessly. And with a touchscreen device, I feel like I have an Android tablet running inside my Linux machine.
But I still don't know what to use it for...
What apps do you use with Waydroid? What use cases do you have for it?
It is true that Waydroid isn't super secure. that being said, it is still just a mostly stock android (unless you download gapps). Root is not exposed to the container so unless an exploit is found it is reasonably secure. There are measures waydroid can take to make it more secure. but as it stands it's "not bad"
as far as I know the SELinux container is configured, whether or not the distro uses it isn't up to waydroid but the packaging and host configuration. If there are issues with the SELinux implementation they need to be brought up.
Waydroid also supports apparmor for some protections when SELinux is not available. OFC it's not as good as selinux (and currently it's set in warning mode so it doesn't actually offer protections out of box, please we need people testing this) https://github.com/waydroid/waydroid/pull/906
If you want to use a VM, and anyone who needs a highish level of security should. Bliss OS is a much better option. Though it doesnt offer "native integration" with the host.
