Loading dataset in obb files

September 16, 2021 - 6:10am #1

Hi, I need to load dataset from obb file because of the large dimension of my Android app (300 Mb).

With Vuforia 9.8, all was allright .... but with the new version (10.1) I receive this error: DATABASE_LOAD_ERROR. On Ios everything is fine.

 

Any help??

Hey there,

 

There are a few things to consider when loading your target datasets from the OBB file:

 

1. Retrieve and copy the dataset files before your Vuforia scene. 

2. You shouldn't have the target behaviour object in your scene, but rather create it 'on the fly'. The behaviour will not be able to locate the file, since it's inside the OBB file, and create the DATABASE_LOAD_ERROR error. You can create targets during runtime like so: https://library.vuforia.com/unity-extension/load-vuforia-targets-sd-card-unity

 

I hope that helps. If not, let me know. 

 

Kind regards,
