由于OpenCV開源圖像處理代碼簡單，因此常用于各種平臺中。采用NDK編程可以方便的使用OpenCV資源。
OpenCV的動態(tài)庫已經(jīng)有了，且編譯對版本有較高的要求，需要加入其它動態(tài)庫的時(shí)候需要在Android.mk修改實(shí)現(xiàn)。

LOCAL_PATH:=$(call my-dir)
#添加OpenCV
include $(CLEAR_VARS)
OpenCV_INSTALL_MODULES := on
OpenCV_CAMERA_MODULES := off
OPENCV_LIB_TYPE :=STATIC
# change this folder path to yours
include /home/zzw/AndroidStudioProjects/opencv_face/OpenCV-android-sdk/sdk/native/jni/OpenCV.mk 

# add mylib 自己的lib
LOCAL_C_INCLUDES += /home/zzw/AndroidStudioProjects/mylib/build-android2/install/include
LOCAL_LDLIBS += -L/home/zzw/AndroidStudioProjects/mylib/build-android/install/lib -lmylib
#生成模型文件的名字
LOCAL_MODULE    := JNIpart
#添加其它可編輯的文件，如ShapeConverter.cpp ，XmlReadSave.cpp
LOCAL_SRC_FILES := squeeze_jni.cpp ShapeConverter.cpp XmlReadSave.cpp

LOCAL_CFLAGS := -O2 -fvisibility=hidden -fomit-frame-pointer -fstrict-aliasing -ffunction-sections -fdata-sections -ffast-math
LOCAL_CPPFLAGS := -O2 -fvisibility=hidden -fvisibility-inlines-hidden -fomit-frame-pointer -fstrict-aliasing -ffunction-sections -fdata-sections -ffast-math
LOCAL_LDFLAGS += -Wl,--gc-sections

LOCAL_CFLAGS += -fopenmp
LOCAL_CPPFLAGS += -fopenmp
LOCAL_LDFLAGS += -fopenmp
#andorid 系統(tǒng)庫
LOCAL_LDLIBS    += -llog -lGLESv2 -lEGL -ljnigraphics
include $(BUILD_SHARED_LIBRARY)

Application.mk文件采用常用的編寫方式：ndkr15版本以下，切記NDK的版本不能太高了

# APP_STL := stlport_static
APP_STL := gnustl_static
# APP_ABI := armeabi armeabi-v7a
APP_CPPFLAGS := -std=c++11 -frtti -fexceptions
#選擇平臺
APP_ABI := armeabi-v7a
APP_PLATFORM := android-14
#NDK_TOOLCHAIN_VERSION := 10
