When built for Android, running any of the example scenes on an Android device only results in the following errors:

In the scene, you are simply presented a box which states no camera was found.

The error prevents any other scripts from running.

On further investigation, this is caused by the lack of Android permissions for access to the Camera.

Manually updating the Unity AndroidManifest resolves the startup issue, but identifies another issue #63

The ARUnityX should manage, resolve and ensure the correct permissions are available and accepted by the user on startup.
