如何在Android Studio中集成OpenCV库？

Question

我无法将opencv库初始化到我的项目中，我尝试了在线解决方案，但仍收到未实现org.opencv.core.Mat.n_Mat()的错误。请告诉我如何解决此错误。

这是我的代码，用于初始化openCV

Mat image = new Mat();
        Bitmap bitmap = null;
        File file;
        if (App.mObjectDetector == null || sToggleMode) {
            String path = null;
            if (!sToggle) {
                sToggle = true;
                String fileName = sFormState + ".jpg";
                path = getFilesDir() + File.separator + sFormRevision + File.separator + fileName;
                sFormRevision = AppInfo.mReport.mReportId.substring(0, 3).toLowerCase();
                file = new File(path);
                sToggleMode = file.exists();
                if (!sToggleMode) {
                    sToggle = false;
                    if (!getSecondaryObjectDetectionFile()) {
                        App.mLogger.d("Using default form for object detection");
                        getDefaultObjectDetector(image);
                    }
                } else {
                    App.mLogger.d("Using custom form for object detection: " + path);
                    bitmap = BitmapFactory.decodeFile(path);
                }
            } else {
                sToggle = false;
                if (!getSecondaryObjectDetectionFile()) {
                    App.mLogger.d("Using default form for object detection");
                    getDefaultObjectDetector(image);
                }
            }
            if (bitmap != null) {
                try {
                    Utils.bitmapToMat(bitmap, image);
                    cvtColor(image, image, Imgproc.COLOR_RGB2BGR);
                    App.mObjectDetector = new ObjectDetector(image);
                    if (App.DEBUG) {
                        String debugFile = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES)
                                .getAbsolutePath() + File.separator + "CARCO" + File.separator + "DebugSample.jpg";
                        App.CopyFile(path, debugFile);
                    }
                } catch (Exception e) {
                    App.mLogger.w(e.getMessage());
                }
            } else {
                App.mLogger.d("CameraActivity-Camera: There is no sample form on this device at: " + path);
            }
        }
