android - Why is the client list empty when I connect as a client? -

-

i'm using android wi-fi direct service discovery. when connection info available, request group info if group formed. reason, when connect client, can group owner group, client list empty. when connect group owner, i'm able group owner , client list. when chat fragment, i'm trying display group owner , clients are. issue group owner device name seems blank, rest of info correct, address (i removed address lines). i've tried requesting group info in few different places, , i'm never able client list when connected client. switch chat fragment when receive service_connected intent.

connecting client:

according 1 of wi-fi direct contributors, group client cannot see list of other clients. group owner have keep track of , inform group clients.
