I’m trying to build an app with AR levels and VR levels in the same project for Android. They work fine alone, but ARCore returns unsupported when used in the same project with Google VR. Is there any special configuration I need to activate in order to make them work together.
I believe they were never designed to be able to work together 
Your best bet would be to PM the following forum user that reprensents Google ARcore:

to find out if there is a workaround. Whatever answer you find out from him it would be great to post it back here for others 
Thanks for the answer. I’ll try that.
