Simple AppIndicator with Vala application under Elementary OS

Yesterday I've been stuck on some hard things. Something that looks simple at first but who's not thrust me :/

Here is what i'm trying to have : An appindicator (statusicon ?) with a custom icon for my application.

Unfortunately, there is nothing I found inside valadoc, except this but it's deprecated and it says we should use Notifications which is really not the same thing I've heard about .vapi Appindicator files, but this is no real documentation about how to use it

If someone can post code about integrating AppIndicator inside vala code, I would be thankful !

Thanks

Have you tried the Vala example included in libappindicator?
