title: Android - after click on button execute c++ code(openCV)
body: <p>I wrote 300 lines script (openCV) in c++ and I would like to execute the script after clicking on button in application for android. The script takes a image as an input and the output is edited image. I read about NDK but I am not very skilled in C++/Java, so I do not understand it. I am just learning how to do it. Can you advise me how to do it simple as possible?</p>
  
  <p><strong>Let's say I have simple UI with one button and after click it execute hello world written in c++.</strong></p>
  
  <p>I know how to code android application but i do not know how to put c++ with android together.</p>
  
  <p>Thank you in advance! </p>
