to include other modules in the project, in the module's Android.mk file - using a shared ( .so ):  PREBUILT_SHARED_LIBRARY  - using a static ( .a ) library:  PREBUILT_STATIC_LIBRARY don't set LOCAL_SRC_FILES one item each LOCAL_PATH := $(call my-dir) include $(CLEAR_VARS) LOCAL_MODULE := mobule_b LOCAL_SRC_FILES := ./lib/module_a.a include $(PREBUILT_STATIC_LIBRARY) include $(CLEAR_VARS) LOCAL_MODULE := module_b LOCAL_SRC_FILES := ./lib/module_b.a include $(PREBUILT_STATIC_LIBRARY)

OS X El Capitan 버전 10.11.3 Xcode 버전 7.2.1 OpenCV 3.1.0 환경에서 잘 동작함. http://cinema4dr12.tistory.com/entry/OpenCV-Setting-OpenCV-Development-Environment-in-Xcode

It is odd that when loading OpenCV NDK module in static statement makes app slow. Don't load the module like this.  static {       System. loadLibrary ( "ndk_module" );  } Load NDK module at onManagerConnected() in BaseLoaderCallback. private BaseLoaderCallback mLoaderCallback = new BaseLoaderCallback( this ) { @Override public void onManagerConnected( int status) { switch (status) { case LoaderCallbackInterface. SUCCESS : { System. loadLibrary ( "ndk_module" ); mOpenCvCameraView .enableView(); } break ; default : { super .onManagerConnected(status); } break ; } } };
