Native OpenCV in Android Studio with face detect

This application is a sample Android Studio project (tested on gradle 3.0.1) with 'Android SDK OpenCV 3.3.1' (https://sourceforge.net/projects/opencvlibrary/files/opencv-android/)

Usage:

Here is how to use this project to run native OpenCV code.

Make sure you have Android SDK up to date, with NDK installed
Download latest OpenCV SDK for Android from OpenCV.org and decompress the zip file.
Clone this project
Create a symlink named jniLibs in app/src/main that points to YOUR_OPENCV_SDK/sdk/native/libs
In app/CMakeLists.txt change line 9 to points to YOUR_OPENCV_SDK/sdk/native/jni/include
Sync gradle
Run the application

Utils:

The openCVLibaray331 library inside the project contains the java code '/openCVLibrary331/src/main/java' copied from the YOUR_OPENCV_SDK/sdk/java/src folder. The aidl folder '/openCVLibrary331/src/main/aidl' contains the contents of YOUR_OPENCV_SDK/sdk/java/src/org/opencv/engine folder, keeping the same package.

For detection we are using a Haar Cascade frontal face detection inserted in res/raw/haarcascade_frontalface_alt.xml

We can find other Haar at: https://github.com/opencv/opencv/tree/master/data/haarcascades
