为何要做这个
我要在framework的PhoneWindowManager.java里面调用LightService.java里面的函数，用来做灯光的提示之类的，为何我要在PhoneWindowManager.java里面加这个呢，这里就不做讨论了，但是直接调用哪些接口是不行的，所以就引进了ipc通信，所以就有了我这篇博客，这其中有个安卓的大神朋友帮我解惑了很多问题
Aidl 和ipc通信之类的我就不讲了，我永远都是实践家，而且我的专长是linux驱动，这个东西也是现在慢慢负责公司产品framework 需要做的才去学习的
要做的文件修改如下：
补丁链接 说明一下是Android 4.4的

第一步：加入aidl文件
frameworks/base/core/java/android/content/pm/ILightManager.aidlframeworks/base/core/java/android/content/pm/LightManager.java //在app里面这个东西是自动生成的，但是这个这个是手动写出来的
第二步：加入service相关的文件还有
frameworks/base/services/java/com/android/server/LightManagerService.java第三步：加入注册需要的一些代码

第四步：在PhoneWindowManager.java加入调用代码
