Probably you are including the complete openCV library folder containing the dll's with your so file. In order to reduce the size you should only include the dlls necessary, in this case the core dll and the imageprocessing dll.

Did you try to use OpenCV Manager (http://docs.opencv.org/android/service/doc/index.html)? It allows you to reduce .apk size.

OpenCV Manager cant be answer for this question. Anyway to lower libopencv_java.so's file size? I think, this file has all modules.

If you need small APK - the only choice is the OpenCV Manager.

If you can't use OpenCV Manager you need to keep libnative_camera_*.so (for VideoCapture class) and libopencv_java.so (for the rest of API) for all supported platforms.
