ClassNotFoundException: com.unity.ads.IUnityAdsShowListener

Hello,

While testing the Ads Package on functionality I encountered a nasty error on an Android Build via Android Logcat.

I hope that the logs can give insight on what is missing or wrong.

In Editor Mode I can view the Preview Editor Ad normally and everything works on that note. But when I build the project and launch it on my Android Device the error messages come and the ad won’t start.

@Zanryu this happens when you install unity ads package from package manager.
you need to download SDK from unity asset store.
