We had used Delayed Initialization because there's only an optional subsection of our game that uses augmented reality, and we didn't need to present the camera permissions alert immediately. When the user chooses to enter the augmented reality scene, we first prompt for camera permissions. Once camera permissions are granted, the user enters the augmented reality scene. When the user enters that scene, we manually initialize Vuforia with VuforiaRuntime.Instance.InitVuforia();

However, now the camera permissions dialogue is presented immediately upon app launch, even though Vuforia is not initialized.

Hi @hololabs @maherahmedraza

Could you please elaborate on the issue? what does not work anymore?

What actions did you perform before the Delayed initialization that are now, not possible anymore? Would it be possible to get a log in which the issue has been reproduced?

Thank you.

Our team is also having issues with Delayed Initialization now. After updating Unity to 2019.3.0f6, Delayed Initialization no longer works. We updated from Vuforia 8.5.9 to 8.6.7 but the issue still persists.

I am using Unity 2019.3.0f5 and Vuforia 8.5.9. But the delayed initialization is not working I have checked the delayed initialization checkbox and i also disable the VuforiaBehaviour Script. After trying different solutions for several hours I decided to downgrade the version of Vuforia to 8.5.8. It didn't work on that one either. So I further downgrade it  to 8.3.9 and it worked. I don't know what is the problem. I think I have worked with Vuforia 8.5.8 few weeks back and the delayed initialization was working but at that time I had lower Version of Unity.. 

Hello,

The article below isn't completely accurate. If you don't want to start into a Vuforia Engine AR experience, you can just start into a scene that does not have the Vuforia ARCamera in it.

Delayed initialization is only useful if you need to execute code before Vuforia is initialized, e.g. to fetch/uncrypt the Vuforia license key, set a driver library, or update the Vuforia Fusion provider.

Found a workaround for this from Unity forums: https://forum.unity.com/threads/do-not-run-vufory-when-the-application-starts.498351

Quote:

To disable Vuforia in a scene, you need to disable the Vuforia Behaviour.

To disable on the Main Camera, add a VuforiaBehaviour script from Component > Scripts > Vuforia in the menu.

Then disable (uncheck) that script component.

This way it's possible to keep "Delayed initialization" enabled and Vuforia doesn't try to start itself too early (before manual init).
