Thank you for your reply Joshua. Yes indeed I had completely missed the adapter code.. I thought that the .jar I had included (a part from the SDK itself) WAS the adapted and that
AdMob was magically using them somehow.
I will give it a go with a high eCPM for my country then. But a part from this there is nothing in the logs that I can check? I have tried looking for "mopub" for now but there is nothing showing up.
Also in your example this declared in AndroidManifest
com.google.ads.AdActivity
I didn't see it it the AdMob Starter Guide. In my app I didn't put this but ads work. What is this for?
