环信官方Demo源码分析及SDK简单应用-IM集成开发详案及具体代码实现
EaseUI
实际工作过程中，我们是用不了太多东西的，如果只是集成个im最多用到的就是聊天列表和聊天页面。
我们来看重头戏EaseUI这个库。
官方文档
其实官方的WiKi已经介绍的特别详细了。官方EaseUI文档
我们来看Demo
我们来看看ChatActivity
封装EaseChatFragment的ChatFragment
那么Demo中是做了一层封装的。
由于业务未涉及，暂不作分析。
总结及其他
其实正常集成，按照于海同学所说也就半天时间，这是因为的确环信的SDK使用起来比较方便。
通过大致的阅读代码，环信的Demo代码写的还是很不错的，功能齐全，注释完整。值得学习和研究。
写在最后
多学习，多积累，多输出。！

由于业务未涉及，暂不作分析。
总结及其他
其实正常集成，按照于海同学所说也就半天时间，这是因为的确环信的SDK使用起来比较方便。
通过大致的阅读代码，环信的Demo代码写的还是很不错的，功能齐全，注释完整。值得学习和研究。
写在最后
多学习，多积累，多输出。！
