I am having the exact same issue. I can do everything perfectly, but since theres an issue with the jar file, I cannot compile, it tells me "Airpush cannot be resolved to a type". Can someone please point me in the right direction?
STOP. YOU CANT MONETIZE THROUGH AIRPUSH ANYMORE. That whole ad format is now illegal. You'll get your developer account suspended by Google if you continue to publish apps with push notifications.
Furthermore, any apps that you currently have published with push notifications must be removed from Google Play by the 22nd of September.
Dude... You were asking for advice on how integrate specifically notification ads. Seeing as how your just a novice, I thought I was helping you out when I warned you. My mistake.
I'm kinda with iliaz on this one =\ It's true that notifications are banned now but interstitials are still a viable option (depending where you put them, I suppose). Airpush isn't out of the picture in the slightest!
