title: Restrict access to download the application on Google Play
body: <p>I'm developing an application that is still in beta version but I'm interested in uploading it to Google Play in order to test the market. </p>
  
  <p>As I mentioned before the application has not been released yet, so I would like to know if it's possible to restrict the access so that only a restrict number of users will be able to download it?</p>
