failed to load dataset in C++ API

December 10, 2018 - 3:45pm #1

Our render engine is using C++, so we have to use the C++ API for Vuforia. The .xml is in correct folder, but every time it's failed to load the dataset. Stepping in the code, the API only returns boolean value, not much helpful information. We've been using Vuforia 7.5. 

We've been tested on several devices, so it's not device specific. We are able to run model target demo in native android and Unity, so it's not license issue. We're able to get image target running, so it's not the issue with rendering routine.

Kind of running out of ideas here, any input would be helpful. Many thanks!

Hello,

Have you attempted to replace your device database with ours in the Vuforia sample app? This should be a straightforward activity and could help to isolate if this is an issue with the device database, or with your code.

Additionally, be aware that a device database contains an XML file *and* a .DAT file - the latter is proprietary to Vuforia. Both need to be loaded by the Vuforia SDK.

Thanks,

Vuforia Engine Support
