Thanks Tal,
To be totally honest, I heavily relied on this clever guy's mail :
https://mail.gnome.org/archives/gtk-devel-list/2011-March/msg00096.html
However, his work was not fully explained, some errors here, some patches &
switches missing there... so I worked hard until I got these d*mn binaries
:-). And then, you had the Vala part of course, but I begin to be
experienced there (see former posts about cross-compilation on my blog).
Now, to go further on this subject :
- Android's windowing system is called SurfaceFlinger. It's far different
from X11/Wayland, and exposes fast no pure C apis ; however you can draw on
it using JNI.
Porting GTK+ to it would be a HUGE work, involving many and more experienced
hackers than I am ;-), so we better find a sponsor for that. QT has already
done that (google for "Necessitas"). GTK+ is mostly pushed by RedHat, who
has shown no interest in mobile devices yet ; Canonical is pushing in this
direction though, but don't they already have a home-made API for their
Ubuntu Tablet stuff ? (need some facts here).
- If we cannot find a sponsor, we can still write a Vala wrapper for simpler
libraries like this one (S4L) :

s-to.html
So it would end to be an Android-specific Vala binding ; but it's not so
bad, you'd need to rewrite your GUI even on QT either, as the screen is lot
smaller and due to mobile-specific ergonomics.
I'm playing with Cairo right now. It's not so hard, good for pure bitmap
operations ; not bad for a start :-) !
PS Tal : the mail about GLib was already posted on gtk-list years ago, so I
better not forward this until I have new stuff.
Regards,
Tarnyko

Very good!
someone had to break his mind until this would success, and you and many others volunteered...
The main problem was GObject and GLib, I think it would interest people in other GNOME mailing list.
I recently also tried myself to find ways to use Vala in Android, and you prove it works!
This also should be a great start for GTK in android, QT is ahead in this race.
