android - XMPP客户端无法连接到XMPP本地主机服务器

Question

我在android下面的代码 - 我使用asmack API。

public XMPPManager(String server, int port) { 
    this.server = server; 
    this.port = port; 

    SmackConfiguration.setPacketReplyTimeout(packetReplyTimeout); 
    config = new ConnectionConfiguration(server, port); 
    config.setSASLAuthenticationEnabled(false); 
    config.setSecurityMode(SecurityMode.disabled); 
    connection = new XMPPConnection(config); 
    try { 
     connection.connect(); 
     connection.login(user, pass); 
    } catch (XMPPException e) { 
     Log.w("Cannot connect to server.", "0"); 
     e.printStackTrace(); 
    } 
    if (connection.isAuthenticated()) { 
     AccountManager manager = connection.getAccountManager(); 
     try { 
     manager.createAccount("test", "test"); 
     } catch (XMPPException e) { 
     Log.w("Cannot create new user -----" + " on the XMPP server.", "0"); 
     } 
    } 

    } 

我在XMPPClient活动创建XMPPManager类的一个实例是这样的：

public class XMPPClient extends Activity { 
    private String username = "user"; 
    private String password = "pass"; 
    private String host  = "127.0.0.1"; 
    private int port  = 5222; 

    @Override 
    public void onCreate(Bundle savedInstanceState) { 
    try { 
     super.onCreate(savedInstanceState); 

     XMPPManager xmppManager = new XMPPManager(host, port); 
    } catch (Exception e) { 

    } 
    } 

} 

我得到的问题如下：

任何想法为什么我收到“无法连接到服务器”。错误？先谢谢你。

Answer 1

我觉得这条线，

private String host = "127.0.0.1"; 

是导致异常..所以..尝试

private String host = "10.0.2.2";或系统的公共IP

Bco'z Android不明白127.0。作为本地主机，你的系统为0.1 ip，这个ip用于仿真器本身。（回送地址）

Answer 2

检查是否你的xmpp服务器配置正确，你可以连接到它。您可以使用任何其他第三方xmpp客户端连接&测试您的服务器。
