I want to develop an AR application to use with AR glasses stated on the question. Is it possible to develop the project in unreal engine and export it as android apk then use that app in one of those glasses which already run on android os? Is there another way(more stable?) to use those glasses with unreal engine ?
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] and there is always the [forums] for you to post and research in.
