Interstitials Ads Fail To Load On Real Test

I am using Interstitials ads on my app. I get test ads while using this code below: AdRequest adRequest = new AdRequest.Builder() .addTestDevice(AdRequest.DEVICE_ID_EMU

Solution 1:

There is not always an ad available. That's why it's a good idea to use mediation to ensure you always have an ad.

04-04 20:56:48.880:I/Ads(27563):Nofillfromadserver.

This log line tells you that no ad was available.
