title: How to get each device's IP address in Wi-Fi Direct scenario?
body: <p>Starting from ICS, Wi-Fi Direct is introduced. Normally, we use the <code>WifiP2pManager</code> class to operate on Wi-Fi Direct, but it seems that it can only retrieve the GroupOwner IP address after connected. But, actually, any device all came negotiate to become the GroupOwner. In Upper Application, we need to get the peer's IP address, or each peer's IP address in a group so that we can send/communicate with them.</p>
  
  <p>How to get each IP address in Wi-Fi Direct? Include own IP address and each peer in the group?</p>
