【问题描述】：

我正在尝试通过一个简单的 android 应用程序连接到我的 XMPP 服务器，我将使用 smack 4.1.0 文档制作该应用程序，即使我遇到了许多错误并且我也是初学者。错误说明如下：

错误：

这个错误是关于什么的，我做错了什么？请帮帮我。

【参考方案1】：

在您的连接通过身份验证后尝试设置名册。如下

@Override
public void authenticated(XMPPConnection arg0, boolean arg1) 

    Log.i(TAG, "authenticated");

    setRoster();

这样设置名册

private void setRoster()

    Log.i(TAG, "setting up roster...");

    roster=Roster.getInstanceFor(connection);

    roster.addRosterListener(this);
    roster.setSubscriptionMode(Roster.SubscriptionMode.manual);

    Log.i(TAG, "***roster set***"); 

打印名册条目

private void printRosterEntries()

    Log.i(TAG, "print roster entries...");

    if (!roster.isLoaded())
        try 
            roster.reloadAndWait();
         catch (NotLoggedInException e) 
            Log.i(TAG, "NotLoggedInException");
            e.printStackTrace();
         catch (NotConnectedException e) 
            Log.i(TAG, "NotConnectedException");
            e.printStackTrace();
         catch (InterruptedException e) 
            Log.i(TAG, "InterruptedException");
            e.printStackTrace();
        

    Collection<RosterEntry> entries=roster.getEntries();

    Log.i(TAG, "entries: "+entries.size());

    for(RosterEntry entry:entries)
    
        Log.i(TAG, "name: "+entry.getName());
        Log.i(TAG, "user: "+entry.getUser());
        Log.i(TAG, "status: "+entry.getStatus());
        Log.i(TAG, "type: "+entry.getType());
    

    Log.i(TAG, "***printing done***");

【参考方案2】：

经过几个小时的研究，我找到了答案，我在添加 configBuilder.setDebuggerEnabled(true); 后修复了这个问题，请查看以下信息以获取更多信息：aSmack 4.0.* XMPPTCPConnection can't connect to OpenFire and Ejabbered (SmackException$NoResponseException)

.
.
.
configBuilder.setResource("test");
configBuilder.setDebuggerEnabled(true);
configBuilder.setSecurityMode(ConnectionConfiguration.SecurityMode.disabled);
