Dataset doesn't load with Android Split Application Binary

Not sure if this is a known issue. But it looks like Vuforia is unable to load Datasets from a split application binary.

Currently testing this solution: https://developer.vuforia.com/forum/unity/load-dataset-android-split-binary-obb

Any chance this will be solved internally?

 

It is known that Vuforia is unable to load Datasets directly from the split binary. That post you linked describes how to pull the data to the correct location to be able to load the Dataset.

Is the solution described in that post not working for you with Unity 2017.2?

 

Currently testing. Looks like paths were changed in the native integration. "QCAR" folder was renamed to "Vuforia".

Unsure about loading the Datasets manually though, is this step necessary after extracting the files from the OBB?

We're using VUMarks only. Is the following code valid/necessary for VUMarks?

Code (CSharp):

1. ImageTracker it = TrackerManager.Instance.GetTracker<ImageTracker>();
2. DataSet dataSet = it.CreateDataSet();
3. dataSet.Load ("Vuforia/data.xml", DataSet.StorageType.STORAGE_ABSOLUTE);
4. it.ActivateDataSet(dataSet);

 

You won't need to run that code if you have the VuMark DataSet loaded and activated in the Vuforia Configuration. Make sure you are running the code to extract from the OBB before Vuforia is initialized.

 

Thanks, with the path name changes it's working again

 

Glad to hear it
