 Bundle autoMatchCriteria = RoomConfig.createAutoMatchCriteria(nop, nop, 0);

    // build the room config:
    RoomConfig roomConfig =
            RoomConfig.builder(mRoomUpdateCallback)
                    .setOnMessageReceivedListener(mOnRealTimeMessageReceivedListener)
                    .setRoomStatusUpdateCallback( mRoomStatusUpdateCallback)
                    .setAutoMatchCriteria(autoMatchCriteria)
                    .build();

    // create room:
    Games.getRealTimeMultiplayerClient(this,  GoogleSignIn.getLastSignedInAccount(this))
            .create(roomConfig);
