After trying to reinstate Waydroid after OTA-2 I hit a problem with the waydroid-extra folder not existing.
This was solved by running:
>sudo su
#mount -o bind /userdata/system-data/etc/waydroid-extra /etc/waydroid-extra/
I can then launch waydroid.
My problem now is that the mounted folder is unmounted when the session ends, but I dont t recall doing anything when originally setting up Waydroid to make this permanent.
Can anyone explain how to permanently bind the folder?
