title: Android WiFi-Direct Group Formation
body: <p>WiFi-Direct supports several ways in which two devises can establish a P2P group connection (i.e. Standard, Autonomous, Persistent...)
  In Android I can't find anything to specify which type of group formation to adopt.</p>
  
  <p>I have noticed that in the WifiP2pManager there are several methods referring to persistent groups stored in the system (such as requestPersistentGroupInfo(...)`)
  but cannot access them unless using Reflection.</p>
  
  <p>Is it fair to assume that Android only supports persistent group connection and that Android discourages removing persistent groups?</p>
