英文:
Could not import the OpenCV Library in Android Studio
问题
我已经下载了Android Studio 4.0.1以及相同版本的OpenCV库。
我创建了一个随机的Java项目，只是为了设置这个库，但当我选择库时（路径是正确的 - "C:\opencv-4.0.1-android-sdk\OpenCV-android-sdk\sdk\java"），它们不显示它并且不让我完成这个操作（请查看下面的图像）。
为什么我无法选择这个库？我正在观看一个YouTube视频（我是新手），那个人看到的情况完全不同。
英文:
I had downloaded the Android Studio 4.0.1 and the same version for OpenCV Library.
I made a random Java project just to set the library, but when I select the library (the path is correct -"C:\opencv-4.0.1-android-sdk\OpenCV-android-sdk\sdk\java") they don't show it and let me finish this action (please see the image below).
Why I can't select the library? I am watching an Youtube video for this (beginner here) and the guy can see it totally different.

不需要选择库。添加此模块，然后执行以下步骤：
打开项目结构-> 依赖项-> 应用程序-> 添加模块依赖项-> 选择opencv模块。
您现在可以访问opencv类。
英文:
You don't need to select library. Add this module then do this steps:
Open Project Structure-> Dependencies-> app -> Add module dependency-> select opencv module.
You can access opencv classes right now.

对我来说，导入项目功能也不起作用，但有效的方法是创建一个新的空项目，清除其构件，然后将OpenCV库的构件从OpenCV-android-sdk\sdk\java\文件夹复制到其中。有6个步骤：
- 将AndroidManifest.xml复制到src/main
- 将源代码复制到src/main/java
- 将res文件夹复制到src/main
- 从OpenCV-android-sdk\sdk\native\libs复制libs文件夹到src/main，并将其重命名为jniLibs
- 创建src\main\aidl文件夹并将文件src\main\java\org\opencv\engine\OpenCVEngineInterface.aidl移动到src\main\aidl\org\opencv\engine\文件夹中
- 在build.gradle中通过指定插件将项目设置为库，如 plugins { id 'com.android.library' } 所示
您可以参考以下图片以查看最终项目结构：

英文:
For me the import project functionality also doesn't work, but what worked is to create a new empty project, clears its artifacts, and copy the OpenCV library artifacts from OpenCV-android-sdk\sdk\java\ folder. There are 6 steps:
- copy AndroidManifest.xml to src/main
- copy sources to src/main/java
- copy res folder to src/main
- copy libs folder from OpenCV-android-sdk\sdk\native\libs to src/main and rename it to jniLibs
- create folder src\main\aidl and move file src\main\java\org\opencv\engine\OpenCVEngineInterface.aidl to folder src\main\aidl\org\opencv\engine\
- in build.gradle set project as library by specifying plugins { id 'com.android.library'}
