环信即时通讯单聊集成，添加好友，实现单聊

前段时间由于项目需要，了解一下环信即时通讯，然后自己通过查资料写了一个基于环信的单聊demo,一下是源码，希望可以帮助到需要的小伙伴。
首先，我们要去环信官网注册账号，这个我就不多说了，注册完登录，创建应用，新建两个测试IM用户，

这里主要用到的是应用标示（Appkey）

好了，在环信官网下载对应的sdk,这个不多说了，最好下载一个文档，里面讲的很详细的。
好了，一下是源码

布局文件就相对简单很多了，登录页面很简单，还是贴出来吧。

主要的来了，AndroidManifest.xml添加权限

还有刚刚第一步的AppKey别忘了

其他的页面就不说了，都是些item,不懂的问我，我QQ：1453022932，集成最主要的是要注意，登录，注册，很有多问题就是接受不到信息，这个是因为回调的时候出了问题或者是忘记注册广播了。
好了，我们运行一下，开两个模拟器,刚刚我已近新建了两个测试IM用户，分别登陆两个模拟器

添加好友

这里有一点Bug,就是好友请求不会立马收到，好友方要注销一下账号，重新登陆再能收到，目前在处理，各位也可以处理下这个问题，

点击同意之后注销一下账号，重新登陆，两个都注销一下，这可能是我代码写的有点问题吧，有兴趣的可以改一下，

点击好友进入聊天页面

还有一些问题，我正在处理，欢迎意见，谢谢大家了。
