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

Install NDK in your SDK manager, if you already installed open app's "build.gradle" replace these lines

sourceSets { main { jni.srcDirs = ['src/main/jni', 'src/main/jniLibs/', 'src/main/jni/'] } }

to

sourceSets.main { jniLibs.srcDir 'src/main/jniLibs' // mention your JNI lib path(where ".so" files contains) jni.srcDirs = [] //disable automatic ndk-build call }

I'm tried to configure OpenCV and its fixed
