I implement Admob in one of my android application. First time it has a banner add bellow of my application. But after adding banner ad in RecylearView after 8 items then problem occurs. 90% cases it returns response code 3.
Maximum time it showing me:
I/Ads: No fill from ad server. W/Ads: Failed to load ad: 3
Here response code: 3 means The ad request was successful, but no ad was returned due to lack of ad inventory. But other apps showing ads frequently in same device.
Notes:
- It showing demo ad when i test in TestDevice
- Problem occurring only non test devices
- Rare cases it successfully return ad.
Can anyone please help me to recover from this issue.Is there any issue in my ad_unit or adMob?
