Hi, After i'm running the app i get this error. I don't find the opencv2 folder

HI @matanel-6over6, you haven't set your own path to the opencv 4 library.

Referring to mine cmakelists.txt, go to the opencv section and edit this set(OPENCV_PATH your-path-to-opencv/opencv-4.0.1-android-sdk).

Make sure to have all the paths set, check: PROJECT_PATH, LIB_DIR, DLIB_PATH. Also make sure to include the source sets in your build.gradle, like this: 

sourceSets {
            main {
                jniLibs.srcDirs = [
                        "src/main/cppLibs/dlib/lib",
                        "src/main/cppLibs/opencv"
                ]
            }
        }
