I remember when I started using AdMobs there was a testing key in one of the packages I used at the time. And as time goes and old/obsolete packages are deleted from my system, so also that testing key...
Anyone still knows where to find/get that testing key? I really need it because of an upcoming project where I want to implement a lot of extra options (get rewards for watching a daily video ad and such - is that even allowed?) which I need to test if they work as intended..
