我创建XMPP客户端的FACEBOOK。 我这样做的Gmail，现在我要创造同样为Facebook。 我GOOGLE了很多关于这得到了一些代码，还是我得到这个类型的错误Not connected to server和service-unavailable(503)

我在这里分享我所做的代码。 

public class ClientJabberActivity extends Activity {

ArrayList<String> m_discussionThread;
ArrayAdapter<String> m_discussionThreadAdapter;
XMPPConnection m_connection;
private Handler m_handler;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    m_handler = new Handler();

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

    final EditText recipient = (EditText) this.findViewById(R.id.recipient);
    final EditText message = (EditText) this.findViewById(R.id.message);
    ListView list = (ListView) this.findViewById(R.id.thread);

    m_discussionThread = new ArrayList<String>();
    m_discussionThreadAdapter = new ArrayAdapter<String>(this,
            R.layout.multi_line_list_item, m_discussionThread);
    list.setAdapter(m_discussionThreadAdapter);

    Button send = (Button) this.findViewById(R.id.send);
    send.setOnClickListener(new View.OnClickListener() {
        public void onClick(View view) {

            String to = recipient.getText().toString();
            String text = message.getText().toString();

            Message msg = new Message(to, Message.Type.chat);
            msg.setBody(text);
            m_connection.sendPacket(msg);
            m_discussionThread.add(" Me  : ");
            m_discussionThread.add(text);
            m_discussionThreadAdapter.notifyDataSetChanged();
        }
    });
}

private void initConnection() throws XMPPException {

    ConnectionConfiguration config = new ConnectionConfiguration(
            "chat.facebook.com", 5222, "chat.facebook.com");
    config.setSASLAuthenticationEnabled(true);
    m_connection = new XMPPConnection(config);
    try {
        SASLAuthentication.registerSASLMechanism("X-FACEBOOK-PLATFORM",
                SASLXFacebookPlatformMechanism.class);
        SASLAuthentication.supportSASLMechanism("X-FACEBOOK-PLATFORM", 0);
        m_connection.connect();          
        m_connection.login(apiKey + "|" + sessionKey, sessionSecret, "Application");
    } catch (XMPPException e) {
        m_connection.disconnect();
        e.printStackTrace();
    }

    Presence presence = new Presence(Presence.Type.available);
    m_connection.sendPacket(presence);

    PacketFilter filter = new MessageTypeFilter(Message.Type.chat);

    m_connection.addPacketListener(new PacketListener() {
        public void processPacket(Packet packet) {
            Message message = (Message) packet;
            if (message.getBody() != null) {
                String fromName = StringUtils.parseBareAddress(message
                        .getFrom());
                m_discussionThread.add(fromName + ":");
                m_discussionThread.add(message.getBody());

                m_handler.post(new Runnable() {
                    public void run() {
                        m_discussionThreadAdapter.notifyDataSetChanged();
                    }
                });
            }
        }
    }, filter);

    ChatManager chatmanager = m_connection.getChatManager();
    chatmanager.addChatListener(new ChatManagerListener() {
        public void chatCreated(final Chat chat,
                final boolean createdLocally) {
            chat.addMessageListener(new MessageListener() {
                public void processMessage(Chat chat, Message message) {
                    System.out.println("Received message: "
                            + (message != null ? message.getBody() : "NULL"));
                    Log.i("CHAT USER",
                            "Received message is: " + message.getBody());
                }
            });
        }
    });
}
 }

这个类SASLXFacebookPlatformMechanism

我怎么可以登录这样xmpp.login(apiKey + "|" + sessionKey, sessionSecret, "Application"); 我知道如何获得acessToken，对Facebook应用程序的关键。 我不知道sessionKey，sessionSecret如何获得这些价值，以及如何解决这个问题。

如果我使用xmpp.login(apiKey, accessToken, "Application"); 我收到此错误--IllegalArgumentException：API密钥或会话密钥不存在

编辑：最后，我得到了阿迈勒解决方案： xmpp.login(apiKey, accessToken, "Application");

Answer 1:

获得访问令牌首先，你必须先登录

fb.authorize(FacebookActivity.this, new String[] {"xmpp_login"},Facebook.FORCE_DIALOG_AUTH, new DialogListner());

SASLXFacebookPlatformMecha类

    super(saslAuthentication);
}

@Override

    getSASLAuthentication().send(new AuthMechanism(NAME, ""));
}

@Override
public void authenticate(String apiKey, String host, String acces_token)
        throws IOException, XMPPException {
    if (apiKey == null || acces_token == null) {
        throw new IllegalArgumentException("Invalid parameters");
    }

    this.access_token = acces_token;
    this.apiKey = apiKey;

    String[] params = query.split("\\&");

        map.put(fields[0], (fields.length > 1 ? fields[1] : null));
    }

    return map;
}
}

我创建ChatManager类

import org.jivesoftware.smack.Chat;
import org.jivesoftware.smack.ChatManagerListener;
import org.jivesoftware.smack.ConnectionConfiguration;
import org.jivesoftware.smack.MessageListener;
import org.jivesoftware.smack.Roster;
import org.jivesoftware.smack.RosterListener;
import org.jivesoftware.smack.SASLAuthentication;
import org.jivesoftware.smack.XMPPConnection;
import org.jivesoftware.smack.XMPPException;
import org.jivesoftware.smack.packet.Presence;
import org.jivesoftware.smack.packet.Presence.Type;
import org.jivesoftware.smackx.pubsub.PresenceState;

public class FacebookChatManager {

private static FacebookChatManager chatManager;
private XMPPConnection connection;
private final String SERVER = "chat.facebook.com";
private final int PORT = 5222;
private final String FACEBOOK_MECHANISM = "X-FACEBOOK-PLATFORM";
private RosterListener rosterListner;

private FacebookChatManager(RosterListener rosterListner)
{
    this.rosterListner = rosterListner;
    ConnectionConfiguration connFig = new ConnectionConfiguration(SERVER,
            PORT);
    connFig.setSASLAuthenticationEnabled(true);
    connection = new XMPPConnection(connFig);
    //setup facebook authentication mechanism
    SASLAuthentication.registerSASLMechanism(FACEBOOK_MECHANISM,
            SASLXFacebookPlatformMecha.class);
    SASLAuthentication.supportSASLMechanism(FACEBOOK_MECHANISM, 0);
}

public static FacebookChatManager getInstance(RosterListener rosterListner)
{
    if(chatManager == null)
    {
        chatManager =  new FacebookChatManager(rosterListner);
    }
    return chatManager;
}

public boolean connect()
{
    try {
        connection.connect();
        return true;
    } catch (XMPPException e) {
        e.printStackTrace();
        connection.disconnect();
    }
    return false;
}

public void disConnect()
{
    connection.disconnect();
}

public boolean logIn(String apiKey, String accessToken)
{
    try {
        connection.login(apiKey, accessToken);
        setPresenceState(Presence.Type.available, "");
        connection.getRoster().addRosterListener(rosterListner);
        return true;
    } catch (XMPPException e) {
        connection.disconnect();
        e.printStackTrace();
    }
    return false;
}

public Roster getRoster()
{
    return connection.getRoster();
}

public Chat createNewChat(String user, MessageListener messageListner)
{
    return connection.getChatManager().createChat(user, messageListner);
}

public void registerNewIncomingChatListner(ChatManagerListener chatManagerListner)
{
    connection.getChatManager().addChatListener(chatManagerListner);
}

public void setPresenceState(Type precenseType, String status)
{
    Presence presence = new Presence(precenseType);
    presence.setStatus(status);
    connection.sendPacket(presence);
}

public Presence getUserPresence(String userId)
{
    return connection.getRoster().getPresence(userId);
}
}

在结束时使用FacebookChatManager类注意到rosterListnr用于获取有关您的朋友的状态变化实现一个你想要的

FacebookChatManager facebookChatManager = FacebookChatManager.getInstance(rosterListner);

if (facebookChatManager.connect()) {
            if (facebookChatManager.logIn(FacebookActivity.APP_ID,
                    access_token)) {
                return facebookChatManager.getRoster();
            }
        }

Answer 3:

连接必须的AsyncTask作出了Android 2.2的高... 

private class AsyncCallWS extends AsyncTask<Void, Void, Void> {
@Override
protected Void doInBackground(Void... params) {
    Log.i(TAG, "doInBackground");
    calculate();
    return null;
}

@Override
protected void onPostExecute(Void result) {
    Log.i(TAG, "onPostExecute");
}

@Override
protected void onPreExecute() {
    Log.i(TAG, "onPreExecute");
}

@Override
protected void onProgressUpdate(Void... values) {
    Log.i(TAG, "onProgressUpdate");
}

public void calculate() 
{
    Session s = Session.getActiveSession();
    ConnectionConfiguration config = new ConnectionConfiguration("chat.facebook.com", 5222);
    config.setSASLAuthenticationEnabled(true);
    XMPPConnection mFbConnection = new XMPPConnection(config);


        SASLAuthentication.registerSASLMechanism("X-FACEBOOK-PLATFORM", SASLXFacebookPlatformMechanism.class);
        SASLAuthentication.supportSASLMechanism("X-FACEBOOK-PLATFORM", 0);

        try {
            mFbConnection.connect();    

            Log.i("XMPPClient",
                    "Connected to " + mFbConnection.getHost());

            mFbConnection.login("7028228197XXXXXX",s.getAccessToken(),"Application");
            Roster roster = mFbConnection.getRoster();
            Collection<RosterEntry> entries = roster.getEntries();

            Log.i("XMPPClient","\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.getName();
                 Log.i("TAG", user);
                }


        } catch (Exception e) {

            e.printStackTrace();
        } 
}
}

不要忘记添加权限。 

private static final List<String> PERMISSIONS = Arrays.asList("xmpp_login");
if(checkPermissions()) 
    {
        AsyncCallWS task = new AsyncCallWS();
        task.execute(); 
    }
    else
    {
         requestPermissions();
    }


public boolean checkPermissions() {
    Session s = Session.getActiveSession();
    if (s!=null) {
        return s.getPermissions().contains("xmpp_login");
    }
    else
        return false;
}

public void requestPermissions() {
    Session s = Session.getActiveSession();
    if (s!=null)
        s.requestNewReadPermissions(new Session.NewPermissionsRequest(this, PERMISSIONS));
}
