Android weixin service
简介
想了很久，为什么Android 微信的服务杀不死？既没有给它权限、又没有手动启动它，为什么它会自动开启接受消息？奇怪了？
先不管它采用什么方法，看看它的源码，然后分析推出自己的结论。

}结论
为什么它的服务杀不死？笔者猜测如下：
1、反射修改系统有关自己app的属性，从而能使自己接受到广播。（暂未从源码中发现）
2、通用SDK库中有调用，QQ、微信、通讯录等共用一个库，这个库判断有该服务则启动。（暂未从源码中发现）
3、定时器循环触发启动，例如：结束进程是有时间间隔，是否利用此间隔在此互相启动？（猜测，未详细跟进源码）
4、把App列为系统等级，从而安装到系统目录。（未从源码中发现）
不管结论对不对，自己动手测试下便知结果。
