Hi
My OpenCV demo on google.play, a superset of some of the demo apps, gives me a blank screen on Android 4.2 I have tried using OpenCV 2.4.3 and 2.4.0 with the same result. Here's my stack trace:

I don't get any compile or run errors, but no frames are being processed because some part of the lib is failing to load. Can anyone point me in the right direction here please? I'm struggling.
Many thanks
Barry
