OpenCV4Android释疑: 透析Android以JNI调OpenCV的三种方式(让OpenCVManager永不困扰)
根据上文中的方法。使用OpenCV3.0.0
Android.mk文件为：
LOCAL_PATH := $(call my-dir) include $(CLEAR_VARS) OpenCV_INSTALL_MODULES:=on OPENCV_CAMERA_MODULES:=off OPENCV_LIB_TYPE:=STATIC //静态没有成功，改为SHARED可以 ifeq ("$(wildcard $(OPENCV_MK_PATH))","") include /home/myc/Documents/sdk/openCV/OpenCV-android-sdk/sdk/native/jni/OpenCV.mk //为了编译依赖OpenCV的so else include $(OPENCV_MK_PATH) endif LOCAL_MODULE := TestOpenCV //生成so的名 LOCAL_SRC_FILES := jni_part.cpp //jni下的cpp文件名 LOCAL_LDLIBS += -lm -llog include $(BUILD_SHARED_LIBRARY)
出现以下几种形式的错误
（1）OPENCV_LIB_TYPE:=STATIC 报了以下一堆错误

没解决
（2）改为 OPENCV_LIB_TYPE:=SHARED之后。编译通过。工程下生成 libs 和 obj目录下的文件
（3）修改Activity文件如下：

将OpenCVLoader.initAsync 这句注释掉，因为这句是使用OpenCVManager的。
修改为加载刚生成的库 System.loadLibrary("TestOpenCV");
（4）需要将 /home/myc/Documents/sdk/openCV/OpenCV-android-sdk/sdk/native/libs/armeabi-v7a/opencv_java.so 拷到libs路径下
（和LibTestOpenCV.so一起）。如果没有拷过来，会报如下错误：

注：在OpenCV Library - 3.0.0-rc1 工程的 StaticHelper.java 中有如下代码：
// If dependencies list is not defined or empty.
result &= loadLibrary("opencv_java");
即在OpenCVLoader初始化过程中，dependencies list 未定义或者为空的情况下，都会默认加载Libopencv_java.so
因此即使Activity中 System.loadLibrary("opencv_java"); 这句被注释掉，还是会报错。
（5）下边这个错调了半天，发现将 System.loadLibrary("TestOpenCV");写成了 System.loadLibrary("LibTestOpenCV");
应该和 LOCAL_MODULE := TestOpenCV 一致

（7）当把
Log.i(TAG,"OpenCV library load!"); if (!OpenCVLoader.initDebug()) { Log.i(TAG,"OpenCV load not successfully"); // OpenCVLoader.initAsync(OpenCVLoader.OPENCV_VERSION_3_0_0, this, mLoaderCallback); } else { // System.loadLibrary("opencv_java"); Log.i(TAG,"start loading libTestOpenCV"); System.loadLibrary("TestOpenCV");// load other libraries Log.i(TAG,"finish loading libTestOpenCV"); mLoaderCallback.onManagerConnected(LoaderCallbackInterface.SUCCESS); }
修改为
Log.i(TAG,"OpenCV library load!"); System.loadLibrary("opencv_java"); Log.i(TAG,"start loading libTestOpenCV"); System.loadLibrary("TestOpenCV");// load other libraries Log.i(TAG,"finish loading libTestOpenCV"); mLoaderCallback.onManagerConnected(LoaderCallbackInterface.SUCCESS);
即跳过 OpenCVLoader.initDebug()过程，打出的log如下：

Log少了很多（仅为测试）
（8）调试中发现，官方给的Sample中。只用java层接口，没用jni层的例子。比如 OpenCV Sample - image-manipulations
只需要拷进去一个Libopencv_java.so，然后注释掉onResume函数中的initAsync这句。不用OpenCVManager就可以运行了
（怀疑如果功能增多需要拷进去其他so）
@Override public void onResume() { super.onResume(); if (!OpenCVLoader.initDebug()) { Log.d(TAG, "Internal OpenCV library not found. Using OpenCV Manager for initialization"); // OpenCVLoader.initAsync(OpenCVLoader.OPENCV_VERSION_3_0_0, this, mLoaderCallback); } else { Log.d(TAG, "OpenCV library found inside package. Using it!"); mLoaderCallback.onManagerConnected(LoaderCallbackInterface.SUCCESS); } }
