Android基于XMPP Smack Openfire开发IM【4】初步实现两个客户端通信

Android基于XMPP Smack Openfire开发IM【四】初步实现两个客户端通信

本博客要介绍的内容：
Openfire做服务器端，两个客户端：Spark、android模拟器。实现两个客户端之间的通信。


第一步：启动openfire服务器。（这里需要用到两个用户登录，前面的博客中已经说明如何添加用户了。）

第二步：启动Spark客户端，如果您还没有Spark，下载请到：http://www.igniterealtime.org/downloads/index.jsp；安装简单。
我电脑的ip为：192.168.0.124，根据自己的修改。
安装后运行如下下图：

第三步：启动eclipse中的项目（另一个客户端），代码如下：

启动后如下图：

第四步：这时，Spark客户端的篮球组中多了一个人。（不清楚组添加、用户添加的请看前面的博客）；

第五步：手机模拟器发送消息给Spark，输入信息后点击发送，

第六步：Spark给手机模拟器发送消息，输入消息后按Ctrl+Enter发送，手机端把收到的消息，通过控制台打印。

第七步：openfire服务器端发送消息给所有的客户端：
