Hi,

I would like to know from where or how did OpenCV load libopencv_java.so file to the device?

The sample project(Face Detection) of OpenCV work fine, but If I try to load OPENCV_VERSION_2_4_3, it's falied to load the libopencv_java file, and the following error was shown:

java.lang.UnsatisfiedLinkError: dlopen failed: "/data/app/org.opencv.engine-1/lib/arm/libopencv_java.so" is 32-bit instead of 64-bit

Why is my libopencv_java is different if I use the same sdk?

There are no 64-bit android libraries for OpenCV 2.4.x.

Try to build your application for 32-bit platform and run it on 64-bit device.

Sorry, but I can't do what they did, cause I can't work with OpenCV 3.0, the reason is that there is no implementation to the constant 'Imgproc.BORDER_REPLICATE' and as I see I don't need to work with this version because the sample projects works fine with version 2.4. am I right?

But there is Core.BORDER_REPLICATE constant available: http://docs.opencv.org/java/3.1.0/org...
