Black Screen and no camera permission about arfoundation-samples

[tdmowrer]

If your bundle identifier is the same, then you won't get prompted for camera permission after granting it the first time.

Things to try:

• If on Android, could you check the logcat output

adb logcat Unity:* Unity-ARCore:* ArPresto:* *:S

• Try Debug.LogFormating the ARSubsystemManager.systemState (this would tell you if, for example, the device is unsupported).

What device are you using?

I am using a Galaxy A6, and arcore works fine.

i not understend wy but with unity 2018.1.1. now seems work

[tdmowrer]

This is difficult to diagnose without any other information. Is there any logcat output (using the command I mentioned in my previous post)?

It would also be helpful to submit a bug with a project that reproduces the issue.

@tdmowrer the project is exactly the arfoundation-samples, i just download it and opened with different version of unity, switced platform and build it on my phones

Same issue, here's what I get when running the logcat command

That output suggests things are generally working. My guess is the phone may think it is unsupported.

Did you try Try Debug.LogFormating the ARSubsystemManager.systemState?

Hi! How do I handle Camera Permission declined in ARFoundation? I see the error being logged in Xcode and it seems to be in API level. But again, the session state seems to be in Initialising. Is there anyway to handle those errors inside ARFoundation itself?

You can check whether camera permission was granted with this API: https://docs.unity3d.com/Packages/[email protected]/api/UnityEngine.XR.ARFoundation.ARCameraManager.html#UnityEngine_XR_ARFoundation_ARCameraManager_permissionGranted
