Sample Error: Exception in callback

September 20, 2017 - 9:15am #6

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 have not been able to recreate this. I made a new project and imported the 2017.2 samples from the asset store, put my license key in, and tested the cloud reco scene on both play mode and an Android device. Are you seeing this issue in play mode or on a device? Do you have any other frameworks or settings active?

Thanks,

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.

Any idea how to fix this?

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. So make a backup, delete all the lib files AS WELL as the plugin files. Then in 2017.3 just go to GameObject -> Vuforia -> ARCamera which will import the new Vuforia. Enable the AR in playersetting and everything works for me from here. It takes me two days to boil it down to this, so stay patient!
