Hi, To start with an internet routine, I am new to AR with Unity. All these concepts start to bite me when I am trying to build a test piece. I understand ARcode/ARkit is for Android/IOS to operate AR apps, but no more than that. I don't know when build an app how that will affect the build, why they show up in XPlugin Management of Unity3D, but Vuforia doesn't, do I still need Vuforia if AR Foundation is available, etc. I am currently trying to do an Architectural AR project that Vufoira's area target seems to be the right path, but I can't even have its Area Target Test app installed to my android and get the scanned database shown there. (Followed the official guide but didn't help much, the folder they suggested is not functional). There seems to be a lot to learn, but could someone tell me where to start? Thank you in advance!
