Waydroid

Waydroid is an application which uses LXC containers to run Android applications on a non-Android system.

Warning: Waydroid requires a Wayland desktop session and cannot be used on X11 directly, but can be run in a nested Wayland session, using e.g. cage.

Warning: Installing Waydroid on your system before running nixos-generate-config will create unnecessary fstab entries that may interfere with system functionality.

Installation

Enable Waydroid in your system configuration:

/etc/nixos/configuration.nix

{
  virtualisation.waydroid.enable = true;
}

After rebuilding and switching, finish the Waydroid install in your shell.

Fetch Waydroid images.
You can add the parameters "-s GAPPS -f" to have GApps support.
$ sudo waydroid init

Before the following steps, you might need to do some GPU adjustments. See the troubleshooting section.

Usage

Start the container

Start the Waydroid LXC container
$ sudo systemctl start waydroid-container

You'll know it worked by checking the journal You should see "Started Waydroid Container".
$ sudo journalctl -u waydroid-container

Start Waydroid session
You'll know it is finished when you see the message "Android with user 0 is ready".
$ waydroid session start

General usage

Start Android UI
$ waydroid show-full-ui

List Android apps
$ waydroid app list

Start an Android app
$ waydroid app launch <application name>

Install an Android app
$ waydroid app install </path/to/app.apk>

Enter the LXC shell
$ sudo waydroid shell

Overrides the full-ui width
$ waydroid prop set persist.waydroid.width 608

Maintenance

Update Android

Use following command to upgrade Android (LineageOS) to a newer version if available

$ sudo waydroid upgrade

Resetting Android Container

Warning: All files of your Android container will be lost

Stop Waydroid container
$ sudo systemctl stop waydroid-container

Removing images and user data
$sudo rm -r /var/lib/waydroid/* ~/.local/share/waydroid

Troubleshooting

GPU Adjustments

In case you have an NVIDIA card or an RX 6800 series, you'll need to disable GBM and mesa-drivers:

/var/lib/waydroid/waydroid_base.prop

ro.hardware.gralloc=default
ro.hardware.egl=swiftshader

Linux 5.18+

Linux 5.18 and later removed ashmem in favor of memfd, so you may need to tell Waydroid (1.2.1 and later) to use the new module:

/var/lib/waydroid/waydroid_base.prop

sys.use_memfd=true

Changing keyboard layout

According to an upstream issue, changing the keyboard layout doesn't seem possible at the moment.

Missing UTF-8 support

According to an upstream issue, Android might fail to display special characters correctly.

Waydroid interferes with suspend/hybernation

According to an upstream issue, Waydroid might interfere with suspend or hybernation. You might have to stop the Android session and container to suspend your machine correctly.

Clipboard sharing

Add wl-clipboard to environment.systemPackages.
