Smack“必须设置本地（用户）JID”错误

Question

无法理解为什么这个错误频繁出现并且应用程序崩溃。

以下错误：

Fatal Exception: java.lang.RuntimeException: Unable to start activity ComponentInfo{com.studyboard/com.studyboard.ChatMessageActivity}: java.lang.IllegalArgumentException: Must have a local (user) JID set. Either you didn't configure one or you where not connected at least once

我尝试使用以下网址中给出的解决方案来解决，但在我的情况下它也不起作用。网址是：- https://community.igniterealtime.org/thread/58150

用于连接到 ejabberd 并使用 Smack 4.1 登录的代码：-

XMPPTCPConnectionConfiguration.Builder config = XMPPTCPConnectionConfiguration.builder();
    config.setSecurityMode(ConnectionConfiguration.SecurityMode.disabled);
    config.setServiceName(Constants.HOST);
    config.setPort(Constants.PORT);
    config.setHost(Constants.HOST);
    config.setDebuggerEnabled(true);
    config.setSendPresence(true);
    config.setUsernameAndPassword(strUsername + "@" + Constants.HOST, strPassword);


    SASLAuthentication.blacklistSASLMechanism("SCRAM-SHA-1");
    SASLAuthentication.blacklistSASLMechanism("DIGEST-MD5");
    SASLAuthentication.unBlacklistSASLMechanism("PLAIN");
    objXmpptcpConnection = new XMPPTCPConnection(config.build());
    objXmpptcpConnection.setUseStreamManagement(true);
    objXmpptcpConnection.setUseStreamManagementResumption(true);
    try {
        objXmpptcpConnection.connect();
        System.out.println("Connected to===>" + objXmpptcpConnection.getHost());
        objXmpptcpConnection.login();

    } catch (XMPPException e) {
        e.printStackTrace();

    } catch (SmackException e) {
        e.printStackTrace();

    } catch (IOException e) {
        e.printStackTrace();

    }

实际错误发生在下面的函数中，它返回我正在聊天的用户的最后状态：-

   public String getLastActivity(XMPPTCPConnection objXmpptcpConnection, String strUser) {

        try {
            LastActivityManager objLastActivityManager = LastActivityManager.getInstanceFor(objXmpptcpConnection);
            LastActivity objLastActivity = null;
            $$ objLastActivity = objLastActivityManager.getLastActivity(strUser + "@" + Constants.HOST);
            System.out.println("MESSAGE:" + objLastActivity.getStatusMessage());
            System.out.println("IDLE TIME::" + objLastActivity.getIdleTime());

            return convertTime(objLastActivity.getIdleTime());

        } catch (SmackException.NoResponseException e) {
            e.printStackTrace();
            return "Offline";
        } catch (XMPPException.XMPPErrorException e) {
            e.printStackTrace();
            return "Offline";
        } catch (SmackException.NotConnectedException e) {
            e.printStackTrace();
            return "Offline";
        }

    }

我已用 $$ 符号标记错误行

用户名错误：

您正在尝试与 user@server@server 连接。不要连接 Jid 部分，它是自动的。

更多，您必须指定用户的资源（例如，设备的名称，默认为 Spark）。

注意：desktop smack 可能会针对 android 使用不同的类。 也许您在身份验证方面有任何其他问题，但指定错误的 JID 可以让您“连接”而不是“登录”，并且遗漏资源会破坏某些功能。
