【问题描述】：

我目前正在使用 Google Play 多人游戏服务开发游戏。一切正常，例如登录 Google+、排行榜和成就。现在我尝试添加多人游戏功能（通过 Google Play 游戏网络）。我的代码没有抛出任何异常，只是不起作用。我的应用程序中唯一的 logcat 输出是“已创建”(private void startQuickGame () )。

public class GameExplorerQuickGame extends Activity implements RoomUpdateListener, RoomStatusUpdateListener 
  private GoogleApiClient client = RXTXChooser.mGoogleApiClient;
  private Room room;
  final static int RC_WAITING_ROOM  = 10002;

  @Override
  public void onCreate (Bundle b) 
    super.onCreate(b);

    if (!this.client.isConnected()) this.client.connect();

    startQuickGame();

  

  private void startQuickGame () 
    Bundle am = RoomConfig.createAutoMatchCriteria(1, 1, 0);

    RoomConfig.Builder roomConfigBuilder = makeBasicRoomConfigBuilder();
    roomConfigBuilder.setAutoMatchCriteria(am);
    RoomConfig roomConfig = roomConfigBuilder.build();

    Games.RealTimeMultiplayer.create(this.client, roomConfig);
    System.out.println("created");     // printed into logcat
  

  // create a RoomConfigBuilder that's appropriate for your implementation
  private RoomConfig.Builder makeBasicRoomConfigBuilder () 
    return RoomConfig.builder(this).setMessageReceivedListener(this.googleRxTx).setRoomStatusUpdateListener(this);
  

  @Override
  public void onRoomConnected (int statusCode, Room room) 
    this.room = room;
    System.out.println("onRoomConnected");
    if (statusCode != GamesStatusCodes.STATUS_OK) 
     else 
        //starting Game Activity...
    
  
  @Override
  public void onJoinedRoom (int statusCode, Room room) 
    this.room = room;
    System.out.println("onJoinedRoom");
    if (statusCode != GamesStatusCodes.STATUS_OK) 
         return;
    

    Intent i = Games.RealTimeMultiplayer.getWaitingRoomIntent(this.client, room, Integer.MAX_VALUE);
    startActivityForResult(i, RC_WAITING_ROOM);
  

  @Override
  public void onRoomCreated (int statusCode, Room room) 
    this.room = room;
    System.out.println("onRoomCreated()");
    if (statusCode != GamesStatusCodes.STATUS_OK) 
        return;
    
    // get waiting room intent
    Intent i = Games.RealTimeMultiplayer.getWaitingRoomIntent(this.client, room, Integer.MAX_VALUE);
    startActivityForResult(i, RC_WAITING_ROOM);
  
  @Override
  public void onActivityResult (int request, int response, Intent intent) 
    if (request == RC_WAITING_ROOM) 
        if (response == Activity.RESULT_OK) 
            //starting Game Activity...
         else if (response == Activity.RESULT_CANCELED) 

            Games.RealTimeMultiplayer.leave(this.client, null, this.room.getRoomId());

         else if (response == GamesActivityResultCodes.RESULT_LEFT_ROOM) 
            Games.RealTimeMultiplayer.leave(this.client, null, this.room.getRoomId());
        
    
  

  @Override
  public void onConnectedToRoom (Room arg0) 
    System.out.println("onConnectedToRoom");
    this.room = arg0;
  

  @Override
  public void onDisconnectedFromRoom (Room room) 
    this.room = room;
    System.out.println("onDisconnectedFromRoom");
    Games.RealTimeMultiplayer.leave(this.client, null, room.getRoomId());
  
  // are we already playing?
  boolean               mPlaying    = false;

  final static int  MIN_PLAYERS = 2;

  // returns whether there are enough players to start the game
  boolean shouldStartGame (Room room) 
    int connectedPlayers = 0;
    for (Participant p: room.getParticipants()) 
        if (p.isConnectedToRoom()) ++connectedPlayers;
    
    return connectedPlayers >= MIN_PLAYERS;
  

  // Returns whether the room is in a state where the game should be canceled.
  boolean shouldCancelGame (Room room) 
    for (Participant p: room.getParticipants()) 
        //          if (!p.isConnectedToRoom()) return true;
    
    return false;
  

  @Override

    System.out.println("onPeersConnected. List.size= " + peers.size());

【问题讨论】：

为了帮助解决您的问题，需要阅读大量代码。你能把你的代码缩小到有问题的区域吗？

我试过了。但我不确定问题的根源在哪里......

【参考方案1】：

我找到了解决方案！

我忘了在线添加： private void startQuickGame () //skipping some lines... RoomConfig.Builder roomConfigBuilder = makeBasicRoomConfigBuilder(); roomConfigBuilder.setAutoMatchCriteria(am); roomConfigBuilder.setRoomStatusUpdateListener(this); //I forgot this line RoomConfig roomConfig = roomConfigBuilder.build(); //skipping some lines... googleAPIClient 因某种奇怪的原因被注销
