「沒有響應從服務器」異常在羣組聊天中使用smack android

Question

我正在使用smack.jar庫。 我曾嘗試使用Android的XMPP通過這個代碼來實現羣聊：

MultiUserChat muc = new MultiUserChat(connection,groupName+"@"+Utils.SERVER_NAME); 
    muc.create("nickname1"); 

    Form form = muc.getConfigurationForm(); 
    Form submitForm = form.createAnswerForm(); 
    for (Iterator fields = form.getFields();fields.hasNext();){ 
     FormField field = (FormField) fields.next(); 
     if(!FormField.TYPE_HIDDEN.equals(field.getType()) && field.getVariable()!= null){ 
      submitForm.setDefaultAnswer(field.getVariable()); 
     } 
    }    
    submitForm.setAnswer("muc#roomconfig_publicroom", true); 
    muc.sendConfigurationForm(submitForm); 
    muc.join("nickname1"); 

變得異常，如「從服務器沒有響應」。有誰知道如何解決它？

我有同樣的問題，因爲我使用域名chat.localhost。確保我們有conference作爲子域multiUserManager.getMultUserChat("roomName@conference.localhost");

而且爲IQ和PacketExtension目的使用ProviderManager也很重要。

public static void configure(ProviderManager pm) { 

    // Private Data Storage 

    pm.addIQProvider("query", "jabber:iq:private", 
      new PrivateDataManager.PrivateDataIQProvider()); 

    // Time 

    try { 

     pm.addIQProvider("query", "jabber:iq:time", 
       Class.forName("org.jivesoftware.smackx.packet.Time")); 

    } catch (ClassNotFoundException e) { 

     Log.w("TestClient", 
       "Can't load class for org.jivesoftware.smackx.packet.Time"); 

    } 

    // Roster Exchange 

    pm.addExtensionProvider("x", "jabber:x:roster", 
      new RosterExchangeProvider()); 

    // Message Events 

    pm.addExtensionProvider("x", "jabber:x:event",
