Android 通过XMPP向gmail帐户发送即时消息

我最近阅读了有关XMPP的文章，我想制作一个可以发送和接收IM消息的应用程序，这样我就可以获得一些使用XMPP的经验。问题是我几乎不知道如何使用XMPP或如何将其与Android一起使用。我想知道是否有人能为我指出如何在Android上使用XMPP的正确方向

谢谢

从XMPP开始，您必须

安装（聊天服务器）

将XMPP客户端jar添加到Android应用程序中

像这样实现PacketListener

}

4.接下来，您需要实现以优雅地处理连接失败

公共类XMPPConnectionFailedException扩展运行时异常{

/**
 * 
 */
private static final long serialVersionUID = 1L;

@Override
public String toString() {

    return "The Chat server or the Connection to the chat server failed";
}

}

5.接下来，您需要实际连接到XMPP服务器的类，下面是一个实现

import org.jivesoftware.smack.ConnectionConfiguration;
import org.jivesoftware.smack.ConnectionListener;
import org.jivesoftware.smack.XMPPConnection;
import org.jivesoftware.smack.filter.MessageTypeFilter;
import org.jivesoftware.smack.filter.PacketFilter;
import org.jivesoftware.smack.packet.Message;
import org.jivesoftware.smack.packet.Presence;
import org.jivesoftware.smack.provider.ProviderManager;
import org.jivesoftware.smackx.PrivateDataManager;

import com.test.chat.MyPacketListener;
import com.testchat.exception.XMPPConnectionFailedException;

public class ChatUtil {

public final static String SERVER_HOST = "serverip";
public final static int SERVER_PORT = 5222;
public final static String SERVICE_NAME = "p2547738.pubip.serverbeach.com";

private static XMPPConnection xmppConnection;

public static String CURRENT_RECIPIENT_CHAT_ID;
public static String CURRENT_RECIPIENT_NAME;

public static final String IN = "IN";
public static final String OUT = "OUT";
public static String CURRENT_RECIPIENT_FB_IMAGE;
public static boolean STARTED = false;

public static XMPPConnection getXmppConnection(String username) throws XMPPConnectionFailedException {

    try {
        if (xmppConnection == null) {
            ConnectionConfiguration config = new ConnectionConfiguration(SERVER_HOST, SERVER_PORT, SERVICE_NAME);
            xmppConnection = new XMPPConnection(config);

        }

        if (!xmppConnection.isConnected()) {
            xmppConnection.connect();
        }


        if (!xmppConnection.isAuthenticated()) {
            xmppConnection.login(username, "123");
            ProviderManager pm = ProviderManager.getInstance();
            pm.addIQProvider("query", "jabber:iq:private",new PrivateDataManager.PrivateDataIQProvider());

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

            xmppConnection.addConnectionListener(new ConnectionListener() {

                   @Override
                   public void reconnectionSuccessful() {
                       System.out.println("reconnectionSuccessful");
                   }

                   @Override
                   public void reconnectionFailed(Exception arg0) {
                       System.out.println("reconnectionFailed");
                   }

                   @Override
                   public void reconnectingIn(int arg0) {
                       System.out.println("reconnectingIn");
                   }

                   @Override
                   public void connectionClosedOnError(Exception arg0) {
                       System.out.println("connectionClosedOnError");
                   }

                   @Override
                   public void connectionClosed() {
                       System.out.println("connectionClosed");
                   }
               });

            MyPacketListener listener = new MyPacketListener();
            xmppConnection.addPacketListener(shareFareChatListener,packetFilter);


        }
        Presence presence = new Presence(Presence.Type.available);
        xmppConnection.sendPacket(presence);

        ChatUtil.STARTED = true;

    } catch (Exception e) {
        throw new XMPPConnectionFailedException();
    }

    return xmppConnection;

}

}

6.最后，您尝试使用用于注册用户的凭据将您的连接到XMPP服务器

私有void connectToChat（最终字符串昵称）{ System.out.println（“连接到聊天室…”）； 类ConnectToChatAsync扩展了AsyncTask{

            @Override
            protected Integer doInBackground(Context... params) {

                try {
                    Listener.currentActivity = context;
                    ChatUtil.getXmppConnection(nickname);

                    return SERVER_SUCCESS_RESPONSE;
                } 

                catch ( XMPPConnectionFailedException e) {
                    System.err.println("XMPPConnectionFailedException : " + e);
                }

                return CONNECTIVITY_PROBLEM;
            }

            @Override
            protected void onPostExecute(Integer result) {
                super.onPostExecute(result);

                if(result == CONNECTIVITY_PROBLEM){
//                      ApplicationDialog.showFeedBackDialog(ProjectConstants.XMPP_CHAT_FAILED, context);
                }
            }
        }

        new ConnectToChatAsync().execute();
    }

这应该在编程上解决，您所要做的就是设置Openfire环境

这些链接应该可以帮助您了解该部门

非常感谢您的实施！不过我不太了解openfire的用法。我能不能只使用google XMPP服务器和端口建立连接，然后发送消息？另外，我已经读到，我们需要使用aSmack而不是Android的Smack。Smack jar可以用吗？您是否浏览了最后两个链接并尝试了t我想Google已经从XMPP服务器转向它的聊天引擎，所以我建议你最好花点时间来了解你正在做的事情的基本知识，这样在任何情况下，如果你陷入一些陈规陋习，你都不会被卡住。我使用了smack.jar，它对我来说很好，但Asmack应该尽可能做到这一点

            @Override
            protected Integer doInBackground(Context... params) {

                try {
                    Listener.currentActivity = context;
                    ChatUtil.getXmppConnection(nickname);

                    return SERVER_SUCCESS_RESPONSE;
                } 

                catch ( XMPPConnectionFailedException e) {
                    System.err.println("XMPPConnectionFailedException : " + e);
                }

                return CONNECTIVITY_PROBLEM;
            }

            @Override
            protected void onPostExecute(Integer result) {
                super.onPostExecute(result);

                if(result == CONNECTIVITY_PROBLEM){
//                      ApplicationDialog.showFeedBackDialog(ProjectConstants.XMPP_CHAT_FAILED, context);
                }
            }
        }

        new ConnectToChatAsync().execute();
    }
