I'm using Unity 5.4 and currently use the in-editor services panel to include the UnityAds SDK. I have AdColony set up and that is working fine, but I since I switched to mediation, I've had no ads served from Unity. I noticed in my LogCat this:
09-02 08:59:29.418 13545-13545/? W/cr_BindingManager: Cannot call determinedVisibility() - never saw a connection for the pid: 13545
09-02 08:59:29.505 13545-13545/? W/Ads: Server parameters: {"gameId":"1071310","gwhirl_share_location":"1","zoneId":"rewardedVideo"}
09-02 08:59:29.510 13545-13545/? W/Ads: Server parameters: {"gwhirl_share_location":"1","app_id":"appf1973c897b754768a4","zone_ids":"vz0dccd8bf37064a6894"}
I have a manual fallback to Unity when AdMob fails to deliver an ad and that works correctly, it just doesn't serve any ads from mediation.
I have the UnityAdsAdapter in the Plugin->Android->GoogleMobileAdsPlugin->libs folder and Unity SDK gets added in automatically.
Any ideas?
Thanks,
Alan
