arcore plugin not being recognised by vuforia when building

August 13, 2018 - 7:36pm #1

Hi,

I'm unable to get Vuforia to recognise the arcore plugin.

core-1.4.0

I follow these instructions:

https://library.vuforia.com/content/vuforia-library/en/articles/Solution/arcore-with-vuforia.html

 

I ALWAYS get this warning when I build.

If you want to enable ARCore support for Vuforia, please follow the steps outlined in the library article below.

I've tried different versions of the plugin, Vuforia and Unity, I've tried various versions of Unity (now on 2018.2.3 because Vuforia 7.2.23 is integrated)

 

Does anyone have a workaround or fix?

 

Many thanks

Scott

Hi,

OK, I can confirm what you say.  PLATFORM_SENSOR_FUSION is now being printed out for the AR Provider.  There are some followup notes (which really deserve a different thread):

- Performance is *extremely* bad.  I'm running on Pixel 2 XL.  Thew equivalent scene flies on an Iphone X.  

- For some reason after uninstalling my app (because Vuforia was continually failing to init) permissions aren't being requested again which resulted in hours of wild-goose-chasing trying to understand why Vuforia wasn't initialising.  I had to go into settings and manually grant permissions.  This isn't something I've seen before.

Cheers

Scott

Hey,

Thanks for the follow up. 

In my app I have to enable/disable AR at times.  I notice that the first enable of Vuforia (and I used Delayed Initialisation btw)  GetActiveFusionProvider returns VUFORIA_SENSOR_FUSION. If I then disable AR because I go into another app mode, the reenable, the value VUFORIA_VISION_ONLY is returned.

Is there a "right" way to toggle AR.  I toggle the ARCamera and VuforiaBehaviour?

Cheers

Scott

I suppose for the purposes of this thread, the plugin is now being recognised, but now there is another issue at play? Should this be a new thread now?

Hello Scott,

Apologies for the delayed response.

I was able to get ARCore 1.4 working with Unity 2018.2.4f1 and Vuforia 7.2.23 successfully. I followed the instructions on this pagehttps://library.vuforia.com/content/vuforia-library/en/articles/Solution/arcore-with-vuforia.html, to get ARCore installed in the project. I also made sure to install ARCore on my device (https://play.google.com/store/apps/details?id=com.google.ar.core).

Once this was set up, I deployed to my device and logged the following value to confirm Vuforia was leveraging ARCore: VuforiaRuntimeUtilities.GetActiveFusionProvider. This field printed out the value PLATFORM_SENSOR_FUSION. I confirmed on this page, https://library.vuforia.com/content/vuforia-library/en/reference/unity/namespaceVuforia.html#afa43fb4756bd67edb0ea1bca50033dce, that this value indicates ARCore has successfully been utilized.

I am seeing the same message you mention in your initial post, "If you want to enable ARCore support for Vuforia, please follow the steps outlined in the library article below." This message is meant as an informative message and not a warning (note that it appears as a regular log message in the Unity console and not as a warning or error). This message does not imply that ARCore is not going to work with your application.

Can you please confirm you are doing the same things I describe above and let me know if you can get ARCore working in your app?

Thanks,

Vuforia Engine Support

Hi there,

I tried 1.2, 1.3, and 1.4.  It doesn't matter about the version.  I also tried it on Windows Unity.  

I should note that it did work for me on an older version, but I had to upgrade Unity (for AR reasons actually).  I think it might have been Unity 2018.2.1.  I can't go back - although I seem to remember I did try running the application on an older version of Unity but as you would know it's hard to go back to an older version of Unity once you upgrade.

Sorry, I have to ask - but did you actually test my scenario? I tried in an empty project, and a completely fresh install of Unity.  I have literally spent a full day trying to get this working with brute force trial and error.  It's personally cost me a LOT of time and effort trying to make it work!!

In my experience Unity 2018.2.X does not recognise the library - or to be more clear Vuforia does not recognise the library.  I'm on macOS 10.13.6. (also tested on Windows 10 Unity 2018.2.3)

Thanks

Scott

Hello,

Although Vuforia does not yet explicitly support ARCore 1.4 in SDK 7.2, our experience is that it does work as ARCore APIs are backwards compatible.

Have you tried integrating with an earlier version of ARCore, such as 1.3. This is a known and tested version of ARCore with Vuforia 7.2.

Thanks,
