What to do when the camera access is denied?

Hi, I just realized there doesn't seem to exist any API to invoke the camera access dialogue in case the user rejects it the first time it appears.

Once the user rejects the camera access, the session fires a "ARSessionFailedEvent" with the string "Camera access not authorized". However, this string seems to be localized which means you can't even rely on it to know if the user rejected camera access because the string will be different in another language.

All the examples I've seen don't take this into consideration and always assume the user accepts camera access at first try.

@jimmya Can you confirm if it's possible to detect this and act accordingly?

Any hints anyone?

 

For anyone wondering the same, you can't, apparently, re-ask the user if the use of the camera is allowed.

This means that if the user denies it the first time you ask, from then on you'll need to warn the user that the camera access has been denied and it has to be re-enabled at the iOS Settings app, under Privacy > Camera.

To know this you'll need to use an external library since this functionality is not part of ARKit. This one works great and it's very lightweight: https://github.com/neogeek/Unity-iOS-Bridge-Test/blob/master/Assets/Scripts/TestBridge.cs#L9

 

But how would one know that the user has denied access for camera?

 

Looks like someone has open source project on this.
