So logged in users can post on to their own profile, wall using the following code. 

      facebook.showDialog( "share", {      name = "My Game",      description = "Play this game!",      href = "https://play.google.com/store/apps/details?id=com.mygame.app" }

But I couldn’t manage to get the user to post on a friends wall.

I tried 

facebook.request( "friends/feed", "POST", { message = "Great app check it out!", href = "https://play.google.com/store/apps/details?id=com.mygame.app" } ) end

but noting happens. How do I do this?
