Question on Q&A forum:


I got my new Samsung Galaxy S4 with Android 4.3. When I try to run my OpenCV app, I get this error on instantiating a Mat():

11-27 16:25:37.298: W/dalvikvm(26236): No implementation found for native Lorg/opencv/core/Mat;.n_Mat:()J

This is how I initialize OpenCV:

boolean ret = OpenCVLoader.initAsync(OpenCVLoader.OPENCV_VERSION_2_4_6, this,

Ret value is true. The mLoaderCallback is never called!
