I am updating my project from ARCore 1.2 (pretty sure) to 1.6. I imported the most up to date unity package for ARCore (1.6) and I am getting the following error in the console:
Assets/GoogleARCore/SDK/Scripts/Api/ApiTrackableTypeExtensions.cs(31,40): error CS0050: Inconsistent accessibility: return type GoogleARCoreInternal.ApiTrackableType' is less accessible than method GoogleARCoreInternal.ApiTrackableTypeExtensions.GetApiTrackableType(this Type)'
I am not sure how to resolve this. The Visual Studio 'quick fix' is not helpful in this case. I have tried reimporting ARCore 1.6 but that did not help.
Seems like that was a leftover file. Removing the /scripts/API folder and then reimporting it updated that folder and fixed the error.
