前边的warning 是获取本地liabrary失效，改为通过OpenCVManager获取opencv_java 库。成功

后边的error是OpenCV初始化成功以后，又加载了mixed_sample库。报错。

暂时注释了这个加载。只导致菜单功能的最后一项不可用。

case LoaderCallbackInterface.SUCCESS:
{
　　Log.i(TAG, "OpenCV loaded successfully");

　　// Load native library after(!) OpenCV initialization
　　System.loadLibrary("mixed_sample");

　　mOpenCvCameraView.enableView();
} break;

后来看了博文 http://blog.csdn.net/lllkey/article/details/42101659

发现要在目录下执行ndk-build。生成了obj文件夹。并且在libs/armeabi-v7a/目录下生成了libmixed_sample.so

再执行工程。成功
