Description of the issue:
While building the ARVoyage application ,the snowball fighting not working.It remains in the connecting screen and then showing error screen.
I think the scene is not getting the camera feed.
We have been researching this issue since yesterday. Can you tell us if your voyage app asked for camera permissions when you first loaded it up? If not then I would suggest that you add the capability checker to the camera. Here is how to do that: Camera Permissions for Android.
Another suggestion would be to make sure that you are properly set up to build for Android. Here is a link for that as well. Building for Android.
