How to setting the ad manager correctly and get the adUnitId?

I try to configure the ad manager, but it always show Error: The ad request was successful, but no ad was returned due to lack of ad inventory.

Hello,

I'm upping this topic because we are currently adding ad-manager in our app and with the same adUnitId, it works well on iOS but we got the error above on android : "Error: The ad request was successful, but no ad was returned due to lack of ad inventory."

Do you have any idea on how to fix this?
Thanks again

Hi Kowaio,

This due to no line items setup or AdX line item in Admanager has no demand. AdX only works based on demand from Buyers. I'd suggest that you setup a test line item with sample creative image.
