Hi all
I am compiling my app for android in unity. I have 3 triggers in the scene. I am using v 3.0.9 of vuforia.
When I run this on the device, sometimes (let say 1 out of 6 times) I find the trackable, but when I move the device or hide the image, the app crashes. I've added a debug print in the "OnTrackableStateChanged" method of my (custom) trackable behaviour, and it is not printed, so I know the crash is inside Vuforia's code.
Here is the whole log of the crash:

These are the highlights:

Have you tried adding your DAT/XML to the ImageTargets sample app in the "StreamingAssets/QCAR/" folder. Does the crash ever occur in Unity PlayMode? A crash only occurring 1/6 times would need you to do further isolation and testing where you could reproduce it consistently. Also, it might be a good idea as you suggested to re-export your DAT/XML from TargetManager just in case.
