title: WIFI_P2P_DISCOVERY_CHANGED_ACTION intent action is never sent
body: <p>I'm doing an application based on wifi direct. According with the <a href="http://developer.android.com/reference/android/net/wifi/p2p/WifiP2pManager.html#WIFI_P2P_DISCOVERY_CHANGED_ACTION" rel="nofollow">documentation</a> I was expecting to receive the WIFI_P2P_DISCOVERY_CHANGED_ACTION intent action when I call discoverPeers(), but for some reason this intent is never sent to my broadcast receiver. Any idea?</p>
  
  <p>Thank you.</p>
