Hi Mike
The expected behavior is that as each server starts, its registered GMS
client components will be notified of the server's own joining the group
and any subsequent joins of other members.
So in essence, server-1 GMS clients should see a JoinNotificationSignal
for server-1, and another for server-2
and in server-2, GMS clients should see a JoinNotificationSignal for
server-2 and another for server-1.
The order here does not matter but correctness is important and if not
its a bug to be fixed.
In the log below, Server-1 seems to be getting its own
JoinNotificationSignal which is correct. Does it ever get the
JoinNotificationSignal for server-2?
On server-2, I am seeing correct behavior.
(Ignore the log statements that show the view contents, as that is an
event coming from the provider implementation - GMS notification signals
are the ones that GMS clients should look in for correctness).
Let me know.
Thanks
