Hi, we've been working with C++ version of model target, which works fine. But the moment initializing the positional device tracker, the app crashed, didn't give feedback if the initializing was succeeded or not. The debugger stopped at the line below, then silently crashed.
posionalDeviceTracker = static_cast<Vuforia::PositionalDeviceTracker*>(trackerManager.initTracker(Vuforia::PositionalDeviceTracker::getClassType()));
We've tested with Vuforia 7.5, and 8.1.7, with the same behavior. Test devices are Galaxy S7, S8, etc.
