為何要做這個(gè)

我要在framework的PhoneWindowManager.java里面調(diào)用LightService.java里面的函數(shù)，用來做燈光的提示之類的，為何我要在PhoneWindowManager.java里面加這個(gè)呢，這里就不做討論了，但是直接調(diào)用哪些接口是不行的，所以就引進(jìn)了ipc通信，所以就有了我這篇博客，這其中有個(gè)安卓的大神朋友幫我解惑了很多問題

Aidl 和ipc通信之類的我就不講了，我永遠(yuǎn)都是實(shí)踐家，而且我的專長(zhǎng)是linux驅(qū)動(dòng)，這個(gè)東西也是現(xiàn)在慢慢負(fù)責(zé)公司產(chǎn)品framework 需要做的才去學(xué)習(xí)的
要做的文件修改如下：

補(bǔ)丁鏈接 說明一下是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里面這個(gè)東西是自動(dòng)生成的，但是這個(gè)這個(gè)是手動(dòng)寫出來的

第二步：加入service相關(guān)的文件還有

frameworks/base/services/java/com/android/server/LightManagerService.java

第三步：加入注冊(cè)需要的一些代碼

modified: frameworks/base/Android.mkmodified: frameworks/base/core/java/android/app/ContextImpl.javamodified: frameworks/base/core/java/android/content/Context.javamodified: frameworks/base/core/java/android/content/ContextWrapper.javamodified: frameworks/base/policy/src/com/android/internal/policy/impl/PhoneWindowManager.javamodified: frameworks/base/services/java/com/android/server/SystemServer.javamodified: frameworks/base/test-runner/src/android/test/mock/MockContext.javamodified: frameworks/base/tools/layoutlib/bridge/src/com/android/layoutlib/bridge/android/BridgeContext.java

第四步：在PhoneWindowManager.java加入調(diào)用代碼

第五步：查看日志
