title: unity development - retrieve device data, permissions?
body: <p>While developing apps for android in android studio, I had to mark permissions in the manifest file, and then use and ask for the persmissions in some other files.</p>
  
  <p>how is that working with the unity engine?</p>
  
  <p>can I write some c# code in order to get the device phone number, or contacts list? if so, how is it possible? where do I need to register permissions, in order to use it and to make sure it will be ok with google play restrictions later on?</p>
  
  <p>thank you</p>
