Hi,

I am trying to modify Android Application Programming with OpenCV 3 first camera application "Second sight" (app works fine ). I am using

OpenCVLoader.initAsync(OpenCVLoader.OPENCV_VERSION_3_0_0,
            this, mLoaderCallback);

to load the library. Everything works (Mat, imgproc.cvtcolor) except imgproc.Canny (possibly more) When I call

Imgproc.Canny(img, edges, 30, 200);

I get

java.lang.UnsatisfiedLinkError: No implementation found for void org.opencv.imgproc.Imgproc.Canny_3(long, long, double, double) (tried Java_org_opencv_imgproc_Imgproc_Canny_13 and Java_org_opencv_imgproc_Imgproc_Canny_13__JJDD)

Why is it not working? Please help.
