title: Implementing ARCore with Xamarin
body: <p>I'm starting to play around with ARCore with Xamarin, and am running into some issues. I see two sample projects:</p>
  
  <ol>
  <li><a href="https://github.com/dotMorten/ARCore.Xamarin" rel="nofollow noreferrer">https://github.com/dotMorten/ARCore.Xamarin</a></li>
  </ol>
  
  <p>This is outdated, when I update all of the Xamarin packages to the latest, it results in a lot of build errors.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.</p>
  
  <ol start="2">
  <li><a href="https://github.com/xamarin/XamarinComponents/tree/master/Android/ARCore" rel="nofollow noreferrer">https://github.com/xamarin/XamarinComponents/tree/master/Android/ARCore</a></li>
  </ol>
  
  <p>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 <a href="https://github.com/xamarin/XamarinComponents/tree/master/Android/ARCore/samples/JavaGL" rel="nofollow noreferrer">github</a>.</p>

    Error CS1566: Error reading resource 'obj.jar' -- 'Could not find a

    (CS1566) (JavaGL)</p>

  <p>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?</p>
