I am trying to integrate admob rewarded ad in my app but it always shows ad failed to load and the following error comes up on logcat
Fail to instantiate adapter com.google.DummyAdapter
I also tried to run the sample rewarded video app on github provided in the admob rewarded doc but same error comes up. I followed the exact procedure as provided in the admob documentation, but still nothing happens at all. Anybody knows what the problem is? or Is there anybody who has already implemented it? I searched and something called meditation adapter i found about which i have no idea. Any other suggestion might be appreciated.
