Is there a way to test adMob in my Android app without subscribing to it? First I want to test it before paying to get it. Maybe with some kind of "common" identifier or other trick?
Admob is free, you do not need to pay for registration and testing, but you will need to register in order to advertise in your application, even test ads.
Also I found Mobclix better than IMO.
