Something seems to be missing where the app requests camera recording access. In one app, built from scratch, everything works as expected, but, when I integrate Vuforia into my current project, Vuforia is not running and there is no camera permissions request and no green camera icon on-screen. I…

Hi @ryan.favale please note that the Vuforia Engine Magic Leap 2 integration instructions have changed, as the setup process in Unity is much easier now with their latest release. Please download the latest version of Engine (10.13) and take a look at the section in the guide regarding permissions.…

Hi Ryan, thank you for your post. Here's a great integration guide to check all the necessary steps required as a starting point. Please let me know if this helps.

Thanks, I almost have this page memorized actually. Been through it about a dozen times now.

@ryan.favale , can you send us a bug report to help us with debugging this? We will also need screenshots and detailed accounts of symptoms.

I'm not sure what other details to add. I'm simply adding Vuforia to the project according to the docs. The only difference I see at runtime is the missing green camera icon that's supposed to pop up and the request for camera recording does not pop-up either.

Above image is the permissions dialog that does not pop up and the GIF above is the green camera / dot icon that does not show up. These only occur on the empty project with Vuforia, and does not happen when I integrate Vuforia into our existing Unity app.

Hi @ryan.favale , Just to confirm, you set the Android permissions for camera access in Project Settings > Magic Leap > Permissions? Can you also please list the Magic Leap OS, Unity SDK and Unity editor versions you are using?

I think you closed this ticket prematurely. I'm running through the same issue. The underlying problem is Vuforia isn't being initialized. The permissions, but also the camera not turning on -- those are symptoms of Vuforia not initializing.

It took a couple of days but here's a solution that works. I'm using Vuforia Engine 10.14.4 with Magic Leap SDK 1.4. Vuforia Engine wasn't starting in my scene. I knew this because the Magic Leap 2's green camera indicator wasn't turning on, and the "Vuforia Initialized" debug message never appeared…
