目录
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。
andoird 官网地址 https://developer.android.google.cn/
1.第一步创建一个工程
2.通过文档下载sdk 顺便做个集成
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
- 地址：https://download.csdn.net/download/weixin_42749765/10989760
- 下边是图片
3.1ainActivity.xml 编写一些功能

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
