OpenCV+Android关键点检测崩溃

我在这个问题上做了大量的研究，并尝试了所有的方法，但没有一种有效，所以是时候对它进行一个新的话题了。 我正在做一个项目，用户将从设备中选择一张图片，程序将返回相同的图片，并在上面绘制关键点。 我以前用openCV制作过另一个程序，现在在android上使用的方式完全相同，只是改变了它的显示方式，而不是一个窗口，一个图像视图。 这是imageView的代码：

public void setPic(View v){
    Intent in=new Intent(Intent.ACTION_GET_CONTENT);
    in.setType("image/*");
    startActivityForResult(in,FILE_REQUEST);
}
protected void onActivityResult(int requestCode, int resultCode, Intent imageReturnedIntent) { 
    super.onActivityResult(requestCode, resultCode, imageReturnedIntent); 

    switch(requestCode) { 
    case FILE_REQUEST:
        if(resultCode == RESULT_OK){  
            Uri selectedImage = imageReturnedIntent.getData();
            InputStream imageStream;
           // exception handle!!!
            try {
                imageStream = getContentResolver().openInputStream(selectedImage);
                Bitmap yourSelectedImage = BitmapFactory.decodeStream(imageStream);
                img.setImageBitmap(yourSelectedImage);

                keyPointDetection(selectedImage.getPath());
            } 

            catch (FileNotFoundException e) {
                e.printStackTrace();
            }
        }
    }
}

这应该是从imageView中捕获关键点并输出所选图片的部分，其中包含关键点：

public static KeyPoint[] keyPointDetection(String filename){
    MatOfKeyPoint keypoints = new MatOfKeyPoint();

    FeatureDetector detector = FeatureDetector.create(FeatureDetector.ORB);
    neki = Highgui.imread(filename);

    detector.detect(neki, keypoints);
    KeyPoint[] keypoint = keypoints.toArray();

    Bitmap resultBitmap = Bitmap.createBitmap(keypoints.cols(),keypoints.rows(),Bitmap.Config.ARGB_8888);;
    Features2d.drawKeypoints(neki,keypoints,neki);
    Utils.matToBitmap(keypoints, resultBitmap);

    Highgui.imwrite("keypoints.jpg",neki);


    return keypoint;
}

并且程序会在LogCat中的以下行中崩溃：
