title: Adding only android app to facebook
body: <p>When I added my android game app to facebook, on game page got next instructions:
  "To fix this error, please set your Canvas URL and/or Secure Canvas URL".</p>
  
  <p>But what I have to do, if I want publishing without canvas app? What I should do? I know it is possible. But no information about this.</p>
  
  <p>On preview screen game looks nice with button "send to smartphone". How I can enable application?</p>
