Can't run Ads on Android.

Hi,

My Game is functioning correctly in Editor, but as soon as I build on Android the Ads never initialize. I've done some investigating and located the error in the Device logs. Any help would be great.

Ever since I downloaded the Unity from Asset store from the guide from here: https://unity3d.com/services/ads/quick-start-guide

I have had nothing but issues with it for Android. Any help from anyone would be amazing!

I had to remove UnityAds.aar from the imported Android folder to get things to work.. but nothing..

If UnityAds.Aar is in my project then i get the following error...

Hold on folks, I think I have it. I enabled Ads via the services and also imported Unity Monetization, Why? I do not know. I need a rubber duck. Please Ignore me, if anyone else gets caught out with this i hope my message helps..

 

Hey, Thanks for getting back to me! I eventually solved the problem by getting rid of Unity Monetization 3.0 altogether, it would crash my android device(with the service option off). It seems to be working correctly now and I am using Ads from the service window as directed by the Unity Quick start guide. If this is wrong please let me know.

I hope this is helpful feedback as a first timer at integrating adverts I found the guides quite contradicting not explaining you should use one method or the other. Then again perhaps I read them wrong. Cheers!

 

I actually agree with you. I thought the guides were not very helpful for anyone starting off with unity ads .the distinction between unity ads and monetization needs to be made very clear which it currently is not.

Ive finally managed to get the test ads to show in the editor but they still dont appear on the android device.

Since ive updated to the new unity 2018 ive been getting errors every single time i import a new sdk. Even from unity plugins. Remote settings gave me a bunch of errors .

 

Hey buddy, would you mind telling me how you managed to get this error report? Looks like its off the device??
