前言：

最近公司打算做先关android 方面的技术，然后招andirod 还挺贵，老板打算让我来搞搞，那就搞一搞，顺便做些总结，从java后台转型快速入手 android 的小策略。

1.第一步创建一个工程

• 文档地址：https://cloud.tencent.com/product/im

 

2.通过文档下载sdk 顺便做个集成

• 文档地址：https://cloud.tencent.com/document/product/269/32679

 

3.献上一个集成的demo

• 功能包括 登录，退出 ，创建群 创建单人回话，创建群回话 ，发送消息，接受解析消息 ，网络发送信息

4.1介绍

• 功能包括 登录，退出 ，创建群 创建单人回话，创建群回话 ，发送消息，接受解析消息 ，网络发送信息
• 实现方式 通过集成sdk
• 然后调用方法
• 在当中出现过获取群回话不成功情况，通过重新用新的sdkappid 生成 usersgin 实现 就ok了
• ok
