android - 无法在 Android 中使用 XMPP 客户端登录到 ejabberd 服务器

Question

我正在尝试使用 Android 中的 XMPP 客户端连接并登录到 ejabberd 服务器。 XMPP 客户端连接到服务器但未登录。我收到异常消息，如服务器无响应。不知道哪里出了问题。

代码如下:

XMPP 客户端.java

    super.onCreate(icicle);
    Log.i("XMPPClient", "onCreate called");

    mRecipient = (EditText) this.findViewById(R.id.recipient);
    Log.i("XMPPClient", "mRecipient = " + mRecipient);

    setListAdapter();

    // Dialog for getting the xmpp settings
    mDialog = new SettingsDialog(this);

    // Set a listener to show the settings dialog

            Log.i("XMPPClient", "Sending text [" + text + "] to [" + to + "]");
            Message msg = new Message(to, Message.Type.chat);
            msg.setBody(text);
            connection.sendPacket(msg);
            messages.add(connection.getUser() + ":");
            messages.add(text);
            setListAdapter();
        }
    });

请任何人提供帮助。

如果您在本地运行服务器，那么您应该将主机设置为 localhost，但是服务(即 XMPP 域)需要设置为服务器上配置的任何内容.它不会是 @domain，而是 domain。
