I integrated Android FAN v4.24.0 SDK as docs says for testing live ads,but I found when first time to call "adView.loadAd()"(adView is a Adview Object), always received error 1001:" No fill,We are not able to serve ads to this person. Please refer to https://developers.facebook.com/docs/audience-network/faq#a12. If you are integrating Audience Network for the first time, you can use test ads https://developers.facebook.com/docs/audience-network/testing.", then I called "adView.loadAd()" again, ad was filled. What's happening and how to avoid this issue? Anyone can help me?
Upgrade your Facebook SDK to v4.25.0.
Fixed
- Fixed no fill on the very first impression when advertising id hasn't been retrieved yet
