title: using remote control for android TV application
body: <p>I'm developing an Android application for TV 
  when I'm trying to test it in the real Android TV 
  I can't navigate to any button or anything using the remote control buttons 
  up, down, left, right.</p>
  
  <p>I have searched about it and I found that I have to use (Enable D-pad Navigation ) but I don't know how to use this , I didn't find any code or tutorial for it 
  My application is so simple. It makes dynamic layout beside each other and each layout has only one button and one recycle view.</p>
