android - 没有 OpenCV 管理器的 Android 上的 OpenCV

Question

我知道之前有人问过我的问题。

但没有任何解决方案适合我。

现在我尝试了这个解决方案:

1. Solution 1

2. Solution 2

3. Solution 3

4. Solution 4

但没有一个对我有用。

我的应用程序项目包含一个 JNI 部分，因此我添加了来自 THIS 的所有提到的行Android.mk 文件教程，

我评论这一行:

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

并添加:

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

在 public void onResume() 之后

当 OpenCV 启动时，我的应用程序卡住了并崩溃了。

这是 LogCat 输出:

是否可以在没有 OpenCV 管理器的情况下使用 OpenCV(也许将他包含在我的应用程序中？) 希望有人能在这里提供帮助。

谢谢!

Answer 1

当然可以。您只需要将特定的 OpenCV 库打包到您的 APK 中。有一个look at my reply here .
