Hello, I am testing the example scene from ARCore unitypackage ( AugumentedImage ), everything works fine on Editor using Instant Preview but when I try to build and install on the phone the screen turns black. I am using an Galaxy S8. Did anyone get a similar problem?
I had the same issue, turn on ARcore supported in player settings > XR settings and make sure you're targeting minimum of 7.0 for Android and turn off multi-threaded rendering as ARcore doesn't support it. Hope this helps : )
I had the issue that the image detection worked in the instant preview but the app only showed the skybox/blue background when building the app and running it on the phone. It seems that ARCore has a bug it stops in the background and your app has no access to the camera image. Restarting the phone and restarting the app worked for me.
