Android aidl在Framework的使用

为何要做这个

Changes not staged for commit:
(use "git add <file>..." to update what will be committed)
(use "git checkout -- <file>..." to discard changes in working directory)

Untracked files:
(use "git add <file>..." to include in what will be committed)

bootable/bootloader/lk/out
frameworks/base/core/java/android/content/pm/ILightManager.aidl
frameworks/base/core/java/android/content/pm/LightManager.java
frameworks/base/services/java/com/android/server/LightManagerService.java

第一步：加入aidl文件

frameworks/base/core/java/android/content/pm/ILightManager.aidl
frameworks/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
