Baroo,
It should be possible to package for Android and use the package in AR devices. You may have to implement coding or third party plugins though - which we cannot help you with. At this time, we do not have documentation on AR but we do have documentation for [VR][1] and there is always the [forums][2] for you to post and research in.
Good luck!
