title: How to execute facebook app as a Native app on Mobile Facebook App and not on the Mobile Browser
body: <p>The question is related to the mobiles.
  I need to execute my facebook app not only via browsers but even inside the Facebook application, and I even would like the app to appear on the left list of my Facebook profile apps (I explain this better in the photos attached). </p>

  <p>I tested many configurations, but nothing worked.</p>
  
  <p>With the current configuration on the mobile I am able to open my facebook app through the browsers only.
  In the Facebook native application if I search for the app, I cannot find it, and so even execute it. 
  At the moment my Facebook app is not published, it is only in the sandbox and visible only to administrators, developers and testers.</p>
  
  <p>I write down my current configuration, so if you have any idea / clue, let me know.
  Thanks in advance.</p>
