Script to start Android LineageOS with Waydroid in an X11 session

Question

I would like to make a script to start the Waydroid Android container (LineageOS).

Currently, I can start a LineageOS virtual phone without issues with:

sudo systemctl start waydroid-container
weston

And then, inside the weston-terminal:

waydroid session start
waydroid show-full-ui

Note that Waydroid only works in a Wayland session manager, and the Weston compositor is a simple way to run it with your ordinary X windows manager.

I do not know how should I insert the last two lines in the Bash launcher script. I tried to export

XDG_SESSION_TYPE=wayland  

but, while the Waydroid session starts, I am clueless on how to push the phone GUI to the Weston compositor.

There are of course X11 solutions, such as Anbox but Waydroid shines in comparison.

Answer 1

The variable to send Waydroid in place (i.e. inside Weston) is WAYLAND_DISPLAY not XDG_SESSION_TYPE. Also, the XWayland server should be activated.

So, make sure that the Waydroid container is on:

systemctl start waydroid-container

Now, you can launch your phone from your terminal/script with:

weston --xwayland &
export WAYLAND_DISPLAY=wayland-1              
sleep 2
waydroid show-full-ui &

Rather than kill Waydroid, a better way to close the phone:

waydroid session stop 

and Ctrl+Alt+Backspace to quit Weston.

For HiDPI diplay, you might add --scale 2 argument to Weston.

This is a script I found here reddit . Hope it helps. Also if it works for you let me know, Im in a similar position too.

#! /usr/bin/bash
if [ "$(systemctl is-active waydroid-container.service)" == 'active' ];then
    killall -9 weston
    sudo systemctl stop waydroid-container.service
    exit
fi
killall -9 weston
sudo systemctl restart waydroid-container.service
if [ -z "$(pgrep weston)" ]; then
    weston --xwayland &> /dev/null &
fi
sleep 2 &&
export XDG_SESSION_TYPE='wayland'
export DISPLAY=':1'
konsole --new-tab --hide-tabbar --hide-menubar -e '/usr/bin/waydroid show-full-ui' &
while [ -n "$(pgrep weston)" ];do
    sleep 1
done
sudo systemctl stop waydroid-container.service

This script works great for me, it starts weston and waydroid and when you close weston window it stops waydriod session automatically! Tested on Ubuntu and ArchLinux.

#!/bin/bash
export WAYLAND_DISPLAY=mysocket
weston --socket=$WAYLAND_DISPLAY --backend=x11-backend.so --width=1920 --height=1080 &
cmd1_pid=$!
waydroid show-full-ui &
wait $cmd1_pid
waydroid session stop
echo 'waydroid session stopped successfully!'
