基于Smack3.0.4+ Openfire3.10.2开发之Android 客户端之四

我们在之前依次介绍openfire部署以及smack常用API的使用，这一节中我们着力介绍如何基于asmack开发一个Android的客户端，本篇的重点在实践，讲解和原理环节，大家可以参考前面我所发布的OpenFire和Smack的相关文章。今天所讲解的文章只是 ：基于Smack3.0.4+ Openfire3.10.2开发之Android
客户端之四（消息会话、联系人、设置与XMPP 服务器交互）。

1、源代码结构介绍：



activity包下存放一些android页面交互相关的控制程序，还有一个些公共帮助类

adapter包存放界面适配器

application包存放时应用程序相关信息

bean包存放应用程序实体对象

db包存放应用程序SQLite封装操作

fragment包存放自定义fragment组件

listener监听器主要存放对XMPP 监听信息封装

server包主要存放应用程序后台服务（主要连接XMPP 服务器）

util中存放一些常用的工具类

view中一些和android的UI相关的显示控件

AndroidManifest.xml为android功能清单的配置文件
