android studio 3.6.3 引入openCV(3.4.3)

安卓新建项目选择 native C++,C++ 14(C++ 11)

 

一、下载Opencv

https://opencv.org/releases/

二、导入Module

 

 

 

 

 

 

 

三、配置opencv代码

1.删除  <uses-sdk android:minSdkVersion="8" android:targetSdkVersion="21" />

 

 

 2.配置opencv的sdk版本，修改和项目app的一样

 

 

 

 

四、复制arm64-v8a和armeabi-v7a到项目的libs目录下

 

 

 

 

五、添加依赖

dependencies {

...
    implementation project(path: ':openCVLibrary343')
    //将打好jar包，添加到依赖中
    implementation fileTree(dir: "$buildDir/native-libs", include: 'native-libs.jar')
}

//以下很重要
//将添加的.so文件，打包成jar
task nativeLibsToJar(type: Jar, description: 'create a jar archive of the native libs') {
    destinationDir file("$buildDir/native-libs")
    baseName 'native-libs'
    from fileTree(dir: 'libs', include: '**/*.so')
    into 'lib/'
}
tasks.withType(JavaCompile) {
    compileTask -> compileTask.dependsOn(nativeLibsToJar)
}
