Multiplayer P2P game connection problem about android-nearby HOT 1 CLOSED

P2P_STAR is meant for 1:N connection topologies, so it's going to be difficult (not impossible, but complicated, because you essentially need master-election) for you to build a self-assembling network using that -- that's because once an Advertiser establishes the first incoming connection, it cannot then make any outgoing connections (because it is now the "1" in the 1:N topology).

A better way to model this might be to have every Advertiser a random number as a part of its endpointName, with the rule that everyone will only connect to the Advertiser with the highest number it sees; that achieves a rudimentary master-election without a prior shared control plane, but you'll need some tweaks like letting all Discoverers discover for some fixed time (like 20 seconds) before ranking all the Advertisers it sees (to decide who the "host" of the group is). What I've mentioned is also not robust in the face of new phones leaving and joining the group, but there's clever ways you can work around that if you give it some thought. :)

Also, in the future, please post questions that are not related to the sample apps themselves on StackOverflow (tagged with https://stackoverflow.com/questions/tagged/google-nearby).

Good luck!
