Sample Error: Exception in callback

By formavip on Wed, 09/20/2017 - 16:15

Hi guys,

I am trying to work with Cloud Recognition on Unity (2017.2.0b11) but is not going well.

I got the Sample Project, put my Access Keys and License Key, but it's returning the following error:

How I could fix that issue?


Hello formavip,

I'm facing the same issue after trying to update a project from Unity 5.5.1. I removed the original Vuforia folder and tried to import the one provided in Unity.

Are you trying to upgrade your project to be used in 2017.2 tarun2000? If so, I recommend checking out this guide: https://library.vuforia.com/content/vuforia-library/en/articles/Solution/migrate-vuforia-62-to-65.html

Thanks,

Hello Vuforia team,

I am also doing the migration and getting the same error as stated below. Migration works fine on iOS device but failing on Android. 

I migrated from Unity 5.6 to Unity 2017.3. I had the same error, the problem was I only removed the lib files and I didn't remove all the plugin files in the Assets/Plugins folder related to Vuforia (search "vuforia" in your assets) before importing the new Vuforia.
