how i can do it? its librrary from vuforia. Its my apk profile&debug in android studio

 

Hello @glutvort ,

You have to update to the latest Vuforia version. Android ARM64 support was only included since Vuforia version 8.1.7.

See Vuforia release notes here: https://library.vuforia.com/articles/Release_Notes/Vuforia-SDK-Release-Notes

 

i updated my project to unity 2019.1.12f1 and download vuforia 8.3.8. and i have many problems. One of the largest - its white screen after game start. I dont see camera image. Maybe you know how to fix it?

end this errors

@glutvort , I recommend that you try Unity 2018.4.6 (LTS) instead of Unity 2019.X.

Since Unity 2019 has a considerable amount of new changes, using Unity 2018.4.6 is safer.

Regarding your errors, after you migrated your project to the new Unity and Vuforia versions, did you update the Vuforia library assets within your project? I recommend removing all old Vuforia library files and re-importing the new library into the project.

 

it didnt help, I download unity 2018.4.6f1, install vuforia from hub, open project, delete vuforia folder, add ARCamera and update vuforia resources.. And i have white screen, I can scan images, but i didnt see camera image. I see my ar content, but dont see real world((
end same error

 

@glutvort, from your error logs the issue seems related to Image Targets, if so, try to see how you are loading them. Are you loading them dynamically or via adding them manually into the Scene?

If you read the error closely, Vuforia is throwing an exception as it is trying to traverse the database of Image Targets but the collection is changed while traversing it. Are you adding/removing Targets while Vuforia is initializing/updating?

Unfortunately I don't know how else to help you. This issue is somehow related to your project. Try to contact Vuforia support.

 

Have you unchecked the striping option ?
