XMPP /臉譜網聊天連接爲Android

Question

public class ClientJabberActivity extends Activity { 

private final static String SERVER_HOST = "chat.facebook.com"; 
private final static int SERVER_PORT = 5222; 
private final static String SERVICE_NAME = "chat.facebook.com"; 
private final static String LOGIN = "xxxxx@chat.facebook.com"; 
private final static String PASSWORD = "xxxxxx"; 


private List<String> m_discussionThread; 
private ArrayAdapter<String> m_discussionThreadAdapter; 
private XMPPConnection m_connection; 
private Handler m_handler; 

/** Called when the activity is first created. */ 
@Override 
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.main); 
    m_handler = new Handler(); 
    try { 
     initConnection(); 
    } catch (XMPPException e) { 
     e.printStackTrace(); 
    } 

    final EditText recipient = (EditText) this.findViewById(R.id.recipient); 
    final EditText message = (EditText) this.findViewById(R.id.message);   
    ListView list = (ListView) this.findViewById(R.id.thread); 

    m_discussionThread = new ArrayList<String>(); 
    m_discussionThreadAdapter = new ArrayAdapter<String>(this, 
      R.layout.multi_line_list_item, m_discussionThread); 
    list.setAdapter(m_discussionThreadAdapter); 

    Button send = (Button) this.findViewById(R.id.send); 
    send.setOnClickListener(new View.OnClickListener() { 
     public void onClick(View view) { 
      String to = recipient.getText().toString(); 
      String text = message.getText().toString(); 

      Message msg = new Message(to, Message.Type.chat); 
      msg.setBody(text); 
      m_connection.sendPacket(msg); 
      m_discussionThread.add("moi :"); 
      m_discussionThread.add(text); 
      m_discussionThreadAdapter.notifyDataSetChanged(); 
     } 
    }); 
} 


private void initConnection() throws XMPPException { 
    //Initialisation de la connexion 
    ConnectionConfiguration config = 
      new ConnectionConfiguration(SERVER_HOST, SERVER_PORT, SERVICE_NAME); 
    m_connection = new XMPPConnection(config); 
    m_connection.connect(); 
    m_connection.login(LOGIN, PASSWORD); 
    Presence presence = new Presence(Presence.Type.available); 
    m_connection.sendPacket(presence); 

    //enregistrement de l'écouteur de messages 
    PacketFilter filter = new MessageTypeFilter(Message.Type.chat); 
    m_connection.addPacketListener(new PacketListener() { 
      public void processPacket(Packet packet) { 
       Message message = (Message) packet; 
       if (message.getBody() != null) { 
        String fromName = StringUtils.parseBareAddress(message 
          .getFrom()); 
        m_discussionThread.add(fromName + ":"); 
        m_discussionThread.add(message.getBody()); 

        m_handler.post(new Runnable() { 
         public void run() { 
          m_discussionThreadAdapter.notifyDataSetChanged(); 
         } 
        }); 
       } 
      } 
     }, filter); 
} 

} 

這段代碼我用來做連接與Facebook聊天，但連接不能建立，我不知道爲什麼。

private final static String LOGIN = "xxxxx@chat.facebook.com"; 

爲：它與Gmail

Answer 1

變化效果很好

private final static String LOGIN = "xxxxx"; 

嘛不完全）。儘管你有這個想法..

Facebook的XMPP規範不包括用於登錄的@ server.here。將其包含在您的用戶名字符串中或完全刪除您的服務器字符串。

Facebook登錄不同的是：
