title: OpenCV Android implementing ORB in AndroidStudio
body: <p>Where can I find a demo/tutorial of using ORB with OpenCV in AndroidStudio. I searched the web any way I could but I did not find anything that would help me.</p>
  
  <p>I want to write an Android app that will detect multiple flat objects in a live video stream from the camera, and Log their appearance in a logfile.</p>
  
  <p>After researching a little on the web I believe the best approach would be using SURF or ORB. However, SURF I believe it's now unavailable since it was aquired by quallcom, it is also not opensource nor free, my best bet would be with ORB but I cannot find any tutorial on how to implement this for Android</p>
  
  <p>Any help will be appreciated.</p>
