安卓实现gtalk的xmpp简单通信

这里尝试用安卓尝试对电脑上的一个gtalk客户端进行推送消息。

项目源代码可去我的Q群共享下载(250395324)

1.首先要有两个google账号，这里我们假设账号一和账号二

2.需要一个xmpp协议（smack）的jar包，下载地址有很多

lz用的是http://beem-project.com/projects/beem/repository/changes/libs/asmack-android-7-beem.jar

3.配置java代码（其中gmail邮箱代表了你的gtalk的账号）

String host = "talk.google.com";
    String port = "5222";
    String service = "google.com";
    String username = "你的google邮箱";
    String password = "邮箱密码";

    // Create a connection
    ConnectionConfiguration connConfig =
            new ConnectionConfiguration(host, Integer.parseInt(port), service);
    XMPPConnection connection = new XMPPConnection(connConfig);

    try {
        Log.v("aaaaaaaaaaaaaaaaaaaa", "start");
        connection.connect();
        Log.i("XMPPClient", "[SettingsDialog] Connected to " + connection.getHost());
    } catch (XMPPException ex) {
        Log.e("XMPPClient", "[SettingsDialog] Failed to connect to " + connection.getHost());
        Log.e("XMPPClient", ex.toString());
        //xmppClient.setConnection(null);
    }


    try {
        connection.login(username, password);
        Log.i("XMPPClient", "Logged in as " + connection.getUser());

        // Set the status to available
        Presence presence = new Presence(Presence.Type.available);
        connection.sendPacket(presence);
        String to = "推送目的地邮箱";
        Message msg = new Message(to, Message.Type.chat);
        msg.setSubject("VideoID");
        msg.setBody("刘新云是sb"); // i is used to indicate this message as sending video ID
        connection.sendPacket(msg);

    } catch (XMPPException ex) {
        Log.e("XMPPClient", "[SettingsDialog] Failed to log in as " + username);
        Log.e("XMPPClient", ex.toString());
            //xmppClient.setConnection(null);
    }

ps.记得配置权限： <uses-permission android:name="android.permission.INTERNET" />

不然请求会被拒绝

如果希望接收消息，记得新建一个方法然后再方法里面监听connection对象

   public void setConnection
   (XMPPConnection
           connection) {

    if (connection != null) {
        // Add a packet listener to get messages sent to us
        PacketFilter filter = new MessageTypeFilter(Message.Type.chat);
        connection.addPacketListener(new PacketListener() {
            public void processPacket(Packet packet) {
                Message message = (Message) packet;
                if (message.getBody() != null) {
                    String fromName = StringUtils.parseBareAddress(message.getFrom());
                    Log.i("XMPPClient", "Got text [" + message.getBody() + "] from [" + fromName + "]");
                    //messages.add(fromName + ":");
                    //messages.add(message.getBody());
                    // Add the incoming message to the list view
                    /*mHandler.post(new Runnable() {
                        public void run() {
                            setListAdapter();
                        }
                    });*/
                }
            }

        }, filter);
    }
}

4.5 然后在 connection.sendPacket(msg);

这句代码下面调用该方法，此时app将监听服务器那边的异动了

this.setConnection(connection);

4.打开你的gtalk看看是不是有一条新的消息（其中你推送的邮箱最好是你加过的好友）

如果希望自己配置服务器的可以使用fireopen这样的开源服务器框架就可自己制作简单即时通信软件了
