In my android application, we only use very basic stuffs from core. I was wondering how to exclude other modules from libopencv_java3.so, so that we can make our app much smaller.

Best, Wayne

rebuild opencv and in cmake command line add -DBUILD_opencv_apps=OFF -DBUILD_opencv_calib3=OFF... and so on except -DBUILD_opencv_core=ON

This one works for me. Thanks a lot! Wayne

I think BUILD_LIST is a good answer too but you will need opencv >3.x (x=4 @berak?)

if you're using opencv3.4, you can also use:

 cmake -DBUILD_LIST=core,imgproc,imgcodecs,video,calib3d,bgsegm,features2d,flann,highgui,java

(a comma seperated list of modules), and specify explicitly, what you want to build (yet i don't think, it's possible to build only the core module)
