question

We're working on Amazon Mobile Ads extension for the marmalade framework. We're using test ads on a Kindle Fire HD. "Some times", everything works fine - we get ads, show them, hide them, refresh them. But other times they don't work at all. The listener says we've got an ad, but it's not showing, or sometimes it shows for a second and then disappears. This is what the log says (error at the bottom): =========== [b]08-22 10:55:13.462: D/AmazonMobileAds AdLayout(2174): Ad size to be determined automatically. 08-22 10:55:13.477: D/AmazonMobileAds
