Hello guys,
I made several changes to the project including upgrading the version of the OpenCV SDK and Android. Please clone again the master and review the README for execution. Any questions just let me know. It is very important to follow the steps of the README mainly those listed below:

• Make sure you have Android SDK up to date, with NDK installed
• Download OpenCV SDK 3.4.3 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_HOME_OPENCV_SDK}/sdk/native/libs
• In app/CMakeLists.txt change line 9 to points to ${YOUR_HOME_OPENCV_SDK}/sdk/native/jni/include
• Sync gradle
• Run the application
