Google documentation states that "Registering an application handler with initialize(Context, Looper, WifiP2pManager.ChannelListener) requires the permissions ACCESS_WIFI_STATE and CHANGE_WIFI_STATE to perform any further peer-to-peer operations." So you should add these permissions to manifest.xml. The next step in your code then should be handling the various WIFI_P2P_STATE_XXX actions received by the broadcast receiver which you'll supply and register ( usually inside onResume() )
