I tried to use the gnome-3-24 extension but that would not work under core20. And the project fails to build under core18 due to some C missing library features and fails to compile.
How can I give the snap access to the freedesktop icons?
I want to add that the desktop extensions are now the recommended way to create a snap for desktop applications. The snapcraft-desktop-helpers project should only be used for a few very specific situations such as 32-bit applications and legacy GTK+ 2 applications.
@adnan338 for your application I would recommend the gnome-3-28 extension. This one is specifically built for GTK 3 applications. It automatically adds the desktop launcher to your snap and includes an number of improvements to make your snap smaller, start quicker, and make it use the system themes.
See GTK 3 applications for a complete tutorial on how to create a snap for a GTK 3 application.
Edit: I didn’t see that you require core20. A gnome extensions for core20 is in the works, but not released yet.
well, it really depends on your project … for snaps that i design specifically for desktop-only use i definitely use the extensions … but i have enough snaps in the store that i want to be used in other contexts (i.e. kiosk setups on core) where i don’t really want to have an additional snap of ~300MB downloaded alongside …
Ok, I agree the desktop helpers can still be useful for kiosks.
Your comment made me curious what the space savings were on the desktop.
gnome-3-28-1804 is 169MB.
gtk-common-themes is 65MB.
When I switched one of my snaps to the extension, its size fell by 92MB.
So you’d need about three snaps before gnome-3-28 saves you space. I’m guessing this will be difficult on a kiosk. On my desktop, I have 12 snaps using gnome-3-28, so it makes sense there.
This doesn’t seem to be the case for gnome-3-34, however. Only 2 snaps use it and its size is 267MB.

What would it take to make a version of this for core22?
