I have got the same issue, it is happened because emulator didn't have a method WifiP2pManager.initialize()

Do you have its documentation . if both devices are on same network then it will transfer files if there is no network will it create hotspot and send the files

Answer 7 · 2018-04-06T15:26:31.000Z

Fully documentation will be ready soon. It works by p2p, it creates a group inside which is selected "implicitly the group owner" and they exchange files among themselves via sockets
