Android基于XMPP实现用户注册、登录、修改密码和注销

即时通讯软件开发 云聊IM 1535℃

需要用到以下几个工具:

Openfire 最新版本(openfire 3.8.1)

下载地址:http://www.igniterealtime.org/downloads/index.jsp

安装配置可参考:http://www.cnblogs.com/hoojo/archive/2012/05/17/2506769.html

Spark 最新版本(Spark 2.6.3)

下载地址:http://www.igniterealtime.org/downloads/index.jsp

ASmack 最新版本 (asmack-jse-buddycloud-2010.12.11.jar)

由于在Android平台下开发 所以我们用到的是 aSmack,与Smack没有很大的区别

下载地址1:http://download.csdn.net/detail/h7870181/6372585 (现在用的就是这个,修改了一些BUG)
下载地址2:http://code.google.com/p/asmack/downloads/list

需要安装的安装好,需要下载的下载好(这里就不多作介绍)。创建项目工程,导入ASmack jar包,OK,下面就一起去学习怎么实现 用户注册、登录、修改密码和注销等一些功能!
