Hi,
Thanks for your help guys, I found what was causing the problem.
The inflater, even if classes are instanciated indirectly, needs a *.class
file for each class. Meaning that you can't use class nesting or anonymous
classes within those that will be inflated.
I moved the Runnable implementation into it's own java file, named it, and
this did the trick.
I can now trigger population of a spinner from native data on the GL thread,
and make it run on the UI thread ! Nice !
Me happy,
Floof
