Google-Play-Services: Creating custom waiting room UI

Question

I am about to implement a real-time-multiplayer for my android application with the google play games services and got some problems to listen to room updates. Iam not that

Answer 1

Since nobody was able to answer my question or whatever, I think it is valid to provide my result of investigation as an answer myself.

I was able to find the important method calls, which are needed for a custom UI implementation. They are basically located in the two interfaces RoomUpdateListener and RoomStatusUpdateListener and need to be provided to the RoomConfig.Builder.

The lifecycle of a game is like the following:

Step 1

• create the room via

Games.RealTimeMultiplayer.create(mGoogleApiClient, rtmConfigBuilder.build());

Step 2

• RoomUpdateListener: onRoomCreated The client attempts to create a real-time room.

Step 3

• RoomStatusUpdateListener: onPeerJoined Called when one or more peer participants join a room.
• RoomStatusUpdateListener: onRoomConnecting One or more participants have joined the room and have started the process of establishing peer connections
• RoomStatusUpdateListener: onP2PConnected Client is successfully connected to a peer participant.
• RoomStatusUpdateListener: onConnectedToRoom The client is connected to the connected set in a room.
• RoomStatusUpdateListener: onPeersConnected Called when one or more peer participants join a room.

Step 4

• RoomUpdateListener: onRoomConnected All the participants in a real-time room are fully connected.

That's it. Now the participants are connected and can send messages via Games.RealTimeMultiplayer.sendReliableMessage and the other send methods.
