环境和工具：

1.openfire

2.spark

3.smack.jar

openfire和spark两个软件，都是直接安装就可以使用的，就没啥说的了。smack的jar包，可以去官网直接下载，一般导入smack和smackx的jar就可以了。

及时的文本消息通讯：

布局：

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:orientation="vertical" >    <Button        android:id="@+id/btn_login"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:text="log In" />    <Button        android:id="@+id/btn_sendmsg"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:text="send Msg" />    <Button        android:id="@+id/btn_logout"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:text="log Out" /></LinearLayout>

活动：

public class TestSmack extends Activity implements OnClickListener {private Button userLogin;private Button userSendmsg;private Button userLogout;private Connection connection;private Handler myhandler;File file = null;@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.acy_testsma);initView();}public void initView() {myhandler = new Handler() {@Overridepublic void handleMessage(android.os.Message msg) {// TODO Auto-generated method stubsuper.handleMessage(msg);String txt = null;switch (msg.what) {case 0:txt = msg.getData().getString("msg");Toast.makeText(TestSmack.this, txt, 1000).show();break;default:break;}}};userLogin = (Button) findViewById(R.id.btn_login);userLogin.setOnClickListener(this);userSendmsg = (Button) findViewById(R.id.btn_sendmsg);userSendmsg.setOnClickListener(this);userLogout = (Button) findViewById(R.id.btn_logout);userLogout.setOnClickListener(this);}/** * 链接服务器 *  * @return */public boolean conServer() {try {// 这里的服务器地址 为pc的ip地址ConnectionConfiguration config = new ConnectionConfiguration("192.168.1.103", 5222);connection = new XMPPConnection(config);connection.connect();return true;} catch (XMPPException e) {// TODO Auto-generated catch blocke.printStackTrace();}return false;}/** * 登录 *  * @param username * @param userpwd * @return */public boolean logIn(String username, String userpwd) {if (connection != null) {try {connection.login("admin", "admin");return true;} catch (XMPPException e) {// TODO Auto-generated catch blocke.printStackTrace();}}return false;}/** * 发送消息 *  * @param username * @param txt */public void sendMsg(String username, String txt) {if (connection != null) {try {Chat chat = connection.getChatManager().createChat("user@jin/Smack", new MessageListener() {@Overridepublic void processMessage(Chat arg0, Message msg) {// TODO Auto-generated method stubBundle bundle = new Bundle();bundle.putString("msg", msg.getBody());android.os.Message message = new android.os.Message();message.what = 0;message.setData(bundle);myhandler.sendMessage(message);}});chat.sendMessage("hello world");} catch (XMPPException e) {// TODO Auto-generated catch blocke.printStackTrace();}}}public void logOut() {if (connection != null) {connection.disconnect();connection = null;}}class MyLogThread implements Runnable {@Overridepublic void run() {// TODO Auto-generated method stubif (conServer() && logIn("", "")) {// to do} else {}}}@Overridepublic void onClick(View v) {// TODO Auto-generated method stubif (v == userLogin) {MyLogThread myLog = new MyLogThread();Thread thread = new Thread(myLog);thread.start();} else if (v == userSendmsg) {sendMsg("", "");} else if (v == userLogout) {if (null != file && file.exists()) {file.delete();file = null;}logOut();}}}

注意：

    127.0.0.1:5222 Exception: XMPPError connecting to 127.0.0.1:5222.; : remote-server-error(502)

远程服务器错误。针对使用模拟器的情况，如果服务端没问题的话，那就是你请求的ip地址跟服务器地址不匹配，把ip地址改为你的电脑ip试试。显然你的pc电脑作为服务器的话，localhost ip地址不是127的那个。

2. Could not read file

报只读的文件系统警告。看了下文件的权限，是075，所以就将文件创建的改为临时路径，就没问题了。
