Android Studio导入OpenCV库

一、 OpenCV 包下载

下载链接 OpenCV 选择Android pack下载后解压

二、 AS导入 OpenCV

1.新建项目选择Import Module导入

2.选择导入的路径D:\AndroidMode\opencv-4.1.0-android-sdk\OpenCV-android-sdk\sdk，修改名称 “OpenCVLibrary410”

3.选择OpenCVLibrary410导入

4.修改OpenCVLibrary410的build.gradle与项目的build.gradle版本保持一致

三、初始化OpenCV库

override fun onResume() {
        super.onResume()
        if (!OpenCVLoader.initDebug()) {
            Log.e("TAG", "Internal OpenCV library not found. Using OpenCV Manager for initialization")
            OpenCVLoader.initAsync(OpenCVLoader.OPENCV_VERSION_3_1_0, this, mLoaderCallback)
        } else {
            Log.e("TAG", "OpenCV library found inside package. Using it!")
            mLoaderCallback.onManagerConnected(LoaderCallbackInterface.SUCCESS)
        }
    }

    //OpenCV库加载并初始化成功后的回调函数
    private val mLoaderCallback = object : BaseLoaderCallback(this) {
        override fun onManagerConnected(status: Int) {
            when (status) {
                SUCCESS -> Log.e("TAG", "成功加载")
                else -> {
                    super.onManagerConnected(status)
                    Log.e("TAG", "加载失败")
                }
            }
        }
    }
