从活动中使用 OpenCV 时 Android 崩溃 [英] Android crashes when using OpenCV from activity

问题描述

我是 OpenCV 的新手，但我相信按照此页面上的说明我已经正确设置了所有内容 link

I am new to OpenCV, but I believe that I have everything set up correctly by following the instructions on this page link

基本上，每当我尝试从 Activity 访问 OpenCV 库中的任何内容时，我的应用都会崩溃.

Basically, my app crashes whenever I try to access anything from the OpenCV library from activity.

以下代码片段为例:

Mat src = new Mat(100, 100, CvType.CV_8UC4);

这里我只是想初始化一个矩阵.当我调试代码时，它进入 Mat.class 文件，然后它会抛出一个Invocation TargetException"，说源附件不包含文件 Invocation TargetException.class 的源."

here I'm just trying to initialise a matrix. When I debug the code, it goes into the Mat.class file, then it will throw a 'Invocation TargetException' saying 'The source attachment does not contain the source for the file Invocation TargetException.class.'

我在 Internet 上详尽地搜索了解决方案，但找不到满意的解决方案，而且我已经在这个问题上困扰了数周.如果需要任何进一步的信息，请告诉我.非常感谢！

I have searched for solutions exhaustively on the Internet but couldn't find a satisfactory one and I've been stuck on this issue for weeks. If any further information is required please let me know. Many thanks in advance!

注意:我在最开始调用 OpenCVLoader 并返回 true，并且我从示例 OpenCV 应用程序中提取了以下代码片段:

Note: I call OpenCVLoader at the very beginning and it returns true, and I have the following code snippet taken from the sample OpenCV app:

private BaseLoaderCallback mLoaderCallback = new BaseLoaderCallback(this) {
    @Override
    public void onManagerConnected(int status) {
        switch (status) {
        case LoaderCallbackInterface.SUCCESS: {
            // TODO: test
            System.loadLibrary("img_proc_utils");
        }
            break;
        default: {
            super.onManagerConnected(status);
        }
            break;
        }
    }
};

推荐答案

原来是我的 Android.mk 有问题.我包括了 OPENCV_INSTALL_MODULES:=on，现在一切都像魅力一样:)

It turned out to be a problem with my Android.mk. I included OPENCV_INSTALL_MODULES:=on and everything works like a charm now :)
