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

主要的来了，AndroidManifest.xml添加权限

    <uses-permission android:name="android.permission.GET_TASKS" />

    <uses-permission android:name="android.permission.VIBRATE" />
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

还有刚刚第一步的AppKey别忘了

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.xmliu.imsample"
    android:versionCode="1"
    android:versionName="1.0" >

        </activity>

        <!-- 设置环信应用的appkey -->
        <meta-data
            android:name="EASEMOB_APPKEY"
            android:value="在这里写你的AppKey" />
        <!-- 声明sdk所需的service SDK核心功能 -->
        <service android:name="com.easemob.chat.EMChatService" />
    </application>

</manifest>

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。
