Android Native create/destroy tracker

Hello,

I created an app for 3d tracking and I want to change the trackingmap when pressing a button, but when I destroy the old tracker, the activity crashes with the following line in the Android Studio log:

A/libc: Fatal signal 11 (SIGSEGV), code 1, fault addr 0x4 in tid 29935 (GLThread 3918)

The code for recreating the tracker:

mWikitudeSDK.getTrackerManager().destroyTracker(mTracker);

mTracker = mWikitudeSDK.getTrackerManager().create3dClientTracker(mPath + mFileName);

mTracker.registerTrackerEventListener(this);

 

However the same code is working for changing a marker when I use 2d tracking.

I also want to load .wtc files from the internal storage (which is working for .wtm files), but I can only load markers from the projects assets folder.

 

Thanks for your help

Hi Daniel,
Thx for your message. We created an internal bug report and have a look at it.

Best regards,
