I have been doing research into whether the arkit sdk can be used to build to android in unity? I can't seem to find a conlcusive answer yet. I am curious to find out because googles arcore sdk can be built to ios using cloud anchors. I was wondering if the arkit plugin could be used on android devices.
I'm in the search for this solution too, but it seems that if we want to make an AR game for both Android and iOS, we must use ARKit and ARCore, and make code that changes the main core or SDK depending on the OS. If you found something, I would really like to know! I will be in the search for it and share anything I can find
I believe the SDK vuforia will allow you to build to both iOS and Android. That is worth trying if you want to build to multi-platforms with one SDK.
