In eg-app-fw meeting 2021-09-08 we demoed using Flatpak to run apps inside AGL demo platform. (Video at https://www.youtube.com/watch?v=nZCSvBNtmHQ)

Here is how to recreate the demo:

1. Set up AGL build environment following usual instructions. Use qemux86-64 target.

2. Check out branch sandbox/samthursfield/flatpak-sdk

  cd meta-agl-demo
  git checkout sandbox/samthursfield/flatpak-sdk

2. Follow Flatpak in AGL guide to modify local.conf and bblayers.conf.

3. Build the QEMU image containing flatpak:

  bitbake agl-demo-platform
  # Output in tmp/deploy/images/qemux86-64/

4. Build the Flatpak SDK and runtime:

  bitbake agl-demo-platform-flatpak-runtime
  bitbake agl-demo-platform-flatpak-sdk
  # Output in ./agl-demo-platform-flatpak-runtime.flatpak/ and ./agl-demo-platform-flatpak-sdk.flatpak/

5. Run local web server to share runtime and SDK (using caddy in this example):

  caddy file-server --listen :8000 --browse .

6. Build the Flatpak app using flatpak-builder

  git clone https://git.automotivelinux.org/apps/ondemandnavi/ --branch sandbox/samthursfield/flatpak
  cd ondemandnavi
  flatpak remote-add --user --no-gpg-verify local-agl http://localhost:8000/agl-demo-platform-flatpak-sdk.flatpak
  flatpak-builder --repo=../../qemux86-64/ondemandnavi.repo ./_build ./org.automotivelinux.apps.Navigation.yml --force-clean --install-deps-from=local-agl --user
  

7. Boot the AGL demo image in qemu and install the Flatpak app. Replace $HOSTNAME with the machine running the web server:

  flatpak remote-add agl-runtime http://$HOSTNAME:8000/agl-demo-platform-flatpak-runtime.repo/ --no-gpg-verify
  flatpak remote-add agl-app http://$HOSTNAME:8000/ondemandnavi.repo --no-gpg-verify
  flatpak install org.automotivelinux.apps.Navigation
  flatpak run --command=navigation org.automotivelinux.apps.Navigation
