'UNITY AR not working on my phone (Android)

my app is reading 3D-point data from a JSON file and displaying them as GameObjects correct on scene view and on gameview after I hit the play button in the editor.

The android mobile phone only shows camera and a canvas but no game objects.

the data are under Assets/Resources/data/points.json

Do you have an idea what went wrong?

Thank you in advance.

Cheers Georg
