无法加载opencv_java3

Question

我正在尝试使用opencv中的VideoCapture，但我有这个错误：

目前我只是想创建VideoCapture，但它不起作用。这是我的代码     private BaseLoaderCallback mLoaderCallback = new BaseLoaderCallback（this）{

    @Override
    public void onManagerConnected(int status) {
        switch (status) {
            case LoaderCallbackInterface.SUCCESS:
            {
                Log.i(TAG, "OpenCV loaded successfully");

                /* Now enable camera view to start receiving frames */
                mOpenCvCameraView.setOnTouchListener(Puzzle15Activity.this);
                mOpenCvCameraView.enableView();
            } break;
            default:
            {
                super.onManagerConnected(status);
            } break;
        }
    }
};

public void onCreate(Bundle savedInstanceState) {
     super.onCreate(savedInstanceState);
    getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);

    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);
    }
    VideoCapture cv=new VideoCapture(); 
} 

我正在使用android studio和opencv 3.0.0。
