Question

我在android中有以下代码 - 我正在使用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");
      }
    }

  }

我正在XMPPClient活动中创建一个XMPPManager类的实例，如下所示：

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) {

    }
  }

}

我遇到的问题如下：

为什么我收到“无法连接到服务器”的任何想法。错误？提前谢谢。

Answer 1

我想这一行，

private String host = "127.0.0.1";

导致异常..所以试试..

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

Bco'z Android不理解你的系统的127.0.0.1 ip作为本地主机，这个ip用于模拟器本身..（循环地址）

Answer 2

检查您的xmpp服务器是否配置正确，并且您可以连接到它。您可以使用任何其他第三方xmpp客户端连接＆amp;测试你的服务器。

android - XMPP客户端无法连接到XMPP localhost服务器
