【问题描述】：

我使用过 asmack-android-17-0.8.3.jar 并使用以下代码。

 private void testLogin()
        ConnectionConfiguration config = new ConnectionConfiguration("chat.facebook.com", 5222,"Smack");
        config.setSASLAuthenticationEnabled(true);
        config.setSecurityMode(ConnectionConfiguration.SecurityMode.enabled);
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.ICE_CREAM_SANDWICH) 
            config.setTruststoreType("AndroidCAStore");
            config.setTruststorePassword(null);
            config.setTruststorePath(null);
         else 
            config.setTruststoreType("BKS");
            String path = System.getProperty("javax.net.ssl.trustStore");
            if (path == null)
                path = System.getProperty("java.home") + File.separator + "etc"
                    + File.separator + "security" + File.separator
                    + "cacerts.bks";
            config.setTruststorePath(path);
        
        XMPPConnection xmpp = new XMPPConnection(config);
        SASLAuthentication.registerSASLMechanism("X-FACEBOOK-PLATFORM",SASLXFacebookPlatformMechanism.class);
        SASLAuthentication.supportSASLMechanism("X-FACEBOOK-PLATFORM", 0);

        Log.i("XMPPClient",
                "Access token to " + mFacebook.getAccessToken());
        Log.i("XMPPClient",
                "Access token to " + mFacebook.getAppId());
        Log.i("XMPPClient",
                "Access token to " + mFacebook.getAccessToken());
        try 
            xmpp.connect();
            Log.i("XMPPClient",
                    "Connected to " + xmpp.getHost());

         catch (XMPPException e1) 
            Log.i("XMPPClient",
                    "Unable to " + xmpp.getHost());

            e1.printStackTrace();
        
        try 
            xmpp.login(APP_ID, mFacebook.getAccessToken());

            Log.i("XMPPClient",
                    " its logined ");

    //get roster
            Roster roster = xmpp.getRoster();
            Collection<RosterEntry> entries = roster.getEntries();
            System.out.println("Connected!");
            System.out.println("\n\n" + entries.size() + " buddy(ies):");
            for (RosterEntry entry : entries) 
                Log.i("test", entry.getName());
                Log.i("test", entry.getUser());
            

          //send a chat message
            ChatManager chatmanager = xmpp.getChatManager();
            Chat newChat = chatmanager.createChat("[e-mail]", new MessageListener() 

                @Override
                public void processMessage(Chat chat, Message message) 
                    // TODO Auto-generated method stub
                      Log.d("test", "message sent = "+ message);
                
            );
            newChat.sendMessage("Cowdy!");

         catch (XMPPException e) 
            e.printStackTrace();
        

已经完成登录，但下面有警告显示，我无法获取名单和聊天。我认为以下警告会导致无法获得名册。如何解决这个问题以及如何获得名册和聊天？请。

【参考方案1】：

试试这个，也许它对你有用，我有同样的问题，在我的情况下，以下解决方案工作正常。

从您的代码中注释以下代码，然后重试，

    config.setSecurityMode(ConnectionConfiguration.SecurityMode.enabled);
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.ICE_CREAM_SANDWICH) 
        config.setTruststoreType("AndroidCAStore");
        config.setTruststorePassword(null);
        config.setTruststorePath(null);
     else 
        config.setTruststoreType("BKS");
        String path = System.getProperty("javax.net.ssl.trustStore");
        if (path == null)
            path = System.getProperty("java.home") + File.separator + "etc"
                + File.separator + "security" + File.separator
                + "cacerts.bks";
        config.setTruststorePath(path);
