Question

我知道之前曾问过我的问题。

但没有解决方案适合我。

现在我尝试了这个解决方案：

Solution 1
Solution 2
Solution 3
Solution 4

但他们中没有人为我工作。

我的应用程序项目包含一个JNI部分，所以我将THIS教程中提到的所有行添加到Android.mk文件中，

我评论这一行：

if(!OpenCVLoader.initAsync(OpenCVLoader.OPENCV_VERSION_2_4_6, this, mLoaderCallback));

并补充道：

    static {
    if (!OpenCVLoader.initDebug()) {
        // Handle initialization error
    }
}

public void onResume()之后

当OpenCV启动时，我的应用程序卡住了。

这是LogCat输出：

是否可以在没有OpenCV管理器的情况下使用OpenCV（可能在我的应用程序中包含他？）希望有人可以在这里提供帮助。

谢谢！

Answer 1

确保您可以这样做。您只需要在APK中打包特定的OpenCV库即可。拥有一个look at my reply here。
