title: Android Wifi Direct: Avoiding user acceptance when connecting to a known peer
body: <p>While connecting to a peer using WiFi Direct, user's permission is required. I know that connection can't be made without user never giving the permission and there's a feature request for this kind of functionality:
  <a href="https://code.google.com/p/android/issues/detail?id=30880">https://code.google.com/p/android/issues/detail?id=30880</a></p>
  
  <p>But I don't need this feature, asking for permission on the first connection is OK (also, more secure). Is there any method such that the permission is asked for the first time only? And when trying to connect to same peer later, the permission is not required.</p>
