Android Facebook聊天示例项目

public void connectToFb() throws XMPPException {

        ConnectionConfiguration config = new ConnectionConfiguration("chat.facebook.com", 5222);
        config.setSASLAuthenticationEnabled(true);
        config.setSecurityMode(SecurityMode.required);
        config.setRosterLoadedAtLogin(true);
        config.setTruststorePath("/system/etc/security/cacerts.bks");
        config.setTruststorePassword("changeit");
        config.setTruststoreType("bks");
        config.setSendPresence(false);
        try {
            SSLContext sc = SSLContext.getInstance("TLS");
            sc.init(null, MemorizingTrustManager.getInstanceList(this), new java.security.SecureRandom());
            config.setCustomSSLContext(sc);
        } catch (GeneralSecurityException e) {
            Log.w("TAG", "Unable to use MemorizingTrustManager", e);
        }
        XMPPConnection xmpp = new XMPPConnection(config);
        try {
            xmpp.connect();
            xmpp.login("user.name", "password"); // Here you have to used only facebookusername from [e-mail]
            Roster roster = xmpp.getRoster();
            Collection<RosterEntry> entries = roster.getEntries();
            System.out.println("Connected!");
            System.out.println("\n\n" + entries.size() + " buddy(ies):");
            // shows first time onliners---->
            String temp[] = new String[50];
            int i = 0;
            for (RosterEntry entry : entries) {
                String user = entry.getUser();
                Log.i("TAG", user);
            }
        } catch (XMPPException e) {
            xmpp.disconnect();
            e.printStackTrace();
        }
        }

推荐答案

XMPP库中的错误。这有一个工作。

Its a bug in XMPP library . There is a work around for that .

步骤1：连接到XMPP。

步骤2：

Step 2: Login to facebook account through xmpp.

步骤3：使用此fql查询获取在线好友列表。

Step 3: get online friend list using this fql query .

    SELECT uid, name, online_presence ,
      sex FROM user WHERE uid IN (SELECT uid2 FROM friend WHERE uid1 = me())

然后我用string [e-mail]连接地址，并通过XMPP。

Then i concat address with string [e-mail] and communicate via XMPP.
