I don't think this will be useful in the long run.
Using termux to ssh into my dev box already gets me access to a full Linux machine. I also think it's preferable relative to what Google is doing here creating a VM under a VM with weird bugs.
by "phone" they mean pixel, so the title should read "google lets other stuff use google, sometimes"
does this allow running applications which need FUSE? I know for termux that's only possible with root.
Maybe this could become a solution to the shitshow of a problem with Android APIs that make it impossible for any music player app to let user delete locally saved music files?
This is about the size of virtual disk of the Linux VMs this app can create in the newer versions of Android - and has nothing to do with actually accessing all of Android's internal filesystem.
