I'm starting to play around with ARCore with Xamarin, and am running into some issues. I see two sample projects:
This is outdated, when I update all of the Xamarin packages to the latest, it results in a lot of build errors. It seems that there were a ton of breaking api changes since this was developed.
This is up to date (I think), but their sample "HelloAR" solution doesn't build. It references a JavaGL project, which is supposed to have an obj.jar file but it doesn't exist on github.
/Users/justintoth/Downloads/XamarinComponents-master/Android/ARCore/samples/JavaGL/CSC: Error CS1566: Error reading resource 'obj.jar' -- 'Could not find a part of the path "/Users/justintoth/Downloads/XamarinComponents-master/Android/ARCore/externals/obj.jar".' (CS1566) (JavaGL)
I'm wondering how others are getting started with ARCore with Xamarin? Were you able to get past the build errors above, or are you using a different Xamarin project?
Obj.jar is in "external" jar via http://oss.sonatype.org/content/repositories/releases/de/javagl/obj
You can look at the cake build file to see how it is downloaded/used as it is contained in the component, same for the arcore.aar.
