ndk.dir error in Android Studio

Question

I was trying to use opencv library, so I imported one of its projects in Android Studio and when I tried to run it I got this error:

Error:Execution faile

Answer 1

OpenCV sample projects haven't support gradle officially. I think it will be easier if you start a new project and configure it to work as in examples. I have implemented a tutorial project using Android Studio + NDK + OpenCV. You may have a look. https://github.com/quanhua92/NDK_OpenCV_AndroidStudio
