OpenCV 3.0 for Android - static initialization not loading new modules

I recently moved my Android project from OpenCV 2.4.10 to OpenCV 3.0.

I statically initialize OpenCV using this code:


When I run my app, I get this exception:

java.lang.UnsatisfiedLinkError: Native method not found: org.opencv.imgcodecs.Imgcodecs.imread_1:(Ljava/lang/String;)J

Imgcodecs is a new module in OpenCV 3.0 which replaces Highgui from OpenCV 2.4.* if I am right.

I can see following output in logs from OpenCV when it initializes:

Version control:               2.4.10
To be built:                 core androidcamera flann imgproc highgui features2d calib3d ml objdetect video contrib photo java legacy ocl stitching superres ts videostab

From the information above I guess that the OpenCVLoader of OpenCV 3.0 initializes only the old modules from 2.4.10. You can see that it loads highgui module which should not be needed anymore.

Is this a bug of new OpenCV or am I missing something? Is there some workaround how to load also the new modules? Thanks.

ah nice find. both the new imgcodecs and videoio modules are also absent from the android docs
