Hi, I want to work on OpenCV with native C++ and trying to build your project. i have encountered a cmake build problem. I think its a simple problem but i still couldn't figure out, maybe you might have an idea.

What went wrong: Execution failed for task ':app:externalNativeBuildDebug'.

Build command failed. Error while executing process C:\Users\sakthivel\AppData\Local\Android\Sdk\cmake\3.6.4111459\bin\cmake.exe with arguments {--build D:\OCVA\opencv_native_androidstudio-master\opencv_native_androidstudio-master\app.externalNativeBuild\cmake\debug\arm64-v8a --target native-lib} ninja: error: '../../../../src/main/jniLibs/arm64-v8a/libopencv_java3.so', needed by '../../../../build/intermediates/cmake/debug/obj/arm64-v8a/libnative-lib.so', missing and no known rule to make it

Hello, It may be a problem with the jniLibs symlink. As you are on windows you should try to copy the entire OPENCV_SDK/sdk/native/libs directory into app/src/main/jniLibs.

So when you browse into app/src/main/jniLibs, you see your arm64-v8a directory.

Hi, thanks for the advice. It worked out well.
