android R版本应用程序窗口流程源码分析 应用启动时，Activity组件在启动之后，在执行完onResume生命周期之后会执行添加窗口到系统、计算窗口大小和位置、应用执行measure-layout-draw、系统窗口状态刷新这几个动作。 1、 addWindow阶段 Activity的启动本质实际最终也是使用WindowManager去addView(add一个DecorView对象)进而使得wms调用addWindow增加一个WindowState对象，而Activity的addView动作发生在Act...... 阅读详情
AI摘要

文章详细分析了Android系统中0-36层层级树的构建，特别是Task、ActivityRecord、WindowToken和WindowState的添加过程。首先，Task作为WindowContainer的子类被添加到层级树中，接着普通WindowToken的加入，然后是ActivityRecord作为Task的成员添加，最后是WindowState的创建和加入。整个过程涉及多个系统服务如ActivityTaskManagerService和WindowManagerService的交互，以及Binder跨进程通信。

hi,粉丝朋友大家好！
上几集已经给大家讲解了如何构建出0-36层的层级树及相关源码分析，这节来分析离我们最近的Task/ActivityRecord/WindowToken/WindowState/等是怎么添加到这个层级树里面去的。

先来看看最后对应的结构树图：
在这里插入图片描述

标记有颜色的就是我们今天要重点源码分析的，主要分为2个部分：

1、Task的加入部分
2、普通的WindowToken加入
因为相对来说ActivityRecord部分比其他WindowToken的多了一个Task
堆栈代码加入：
在这里插入图片描述

在WindowContainer加入堆栈打印来追踪：

home task创建：

日志比较多，大家可以拷贝到notepad进行观看，这里我们先重点关注home task相关：
结合以前dumpsys activity containers发现home task直接被TaskDisplayArea持有为孩子，这里可以明显看出Task{a13d730 #1 type=home 是在第一次创建WMS就已经创建好了，通过的是
TaskDisplayArea.getOrCreateRootHomeTask开始一直到
com.android.server.wm.WindowContainer.addChild

DefaultTaskDisplayArea@243571827 addChild child = Task{a13d730 #1 type=home ?? U=0 visible=false visibleRequested=false mode=undefined translucent=true sz=0}

接下来 是home task加入一个具体Launcher的task，这里最开始当然是我们的FallbackHome

Task{a13d730 #1 type=home ?? U=0 visible=true visibleRequested=false mode=fullscreen translucent=true sz=0} addChild Comparator child = Task{63f31d4 #2 type=undefined A=1000:com.android.settings.FallbackHome U=0 visible=false visibleRequested=false mode=undefined translucent=true sz=0}

具体堆栈可以看出是ActivityManagerService.systemReady时候触发了ActivityTaskManagerService$LocalService.startHomeOnAllDisplays然后把HomeActivity拉起，由于此时还是加密状态，所以获取的的Home当然是setting的fallbackhome

com.android.server.wm.RootWindowContainer.startHomeOnAllDisplays(RootWindowContainer.java:1405)
com.android.server.wm.ActivityTaskManagerService$LocalService.startHomeOnAllDisplays(ActivityTaskManagerService.java:5892)
com.android.server.am.ActivityManagerService.systemReady(ActivityManagerService.java:8203)

再接下来是ActivityRecord的放入：

Task{63f31d4 #2 type=undefined A=1000:com.android.settings.FallbackHome U=0 rootTaskId=1 visible=true visibleRequested=false mode=fullscreen translucent=true sz=0} addChild child = ActivityRecord{983a135 u0 com.android.settings/.FallbackHome}

触这里和Task一样流程，都是因为ActivityStartController.startHomeActivity(ActivityStartController.java:179)导致：

在这里插入图片描述

WindowState的加入：

因为一般都是WindowToken来作为WindowState的父亲，ActivityRecord是WindowToken的子类：

ActivityRecord{983a135 u0 com.android.settings/.FallbackHome} t2} addChild Comparator child = Window{ae9b359 u0 com.android.settings/com.android.settings.FallbackHome}

这里是触发ActivityRecord加入WindowState,这个堆栈看明显是个应用端跨进程调用过来的，对这里也相对较熟悉，应用跨进程调用addToDisplayAsUser：

其他WindowToken类型的加入

这里WindowContainer的addChild堆栈需要加入WindowToken的判断
在这里插入图片描述这里因为WindowToken的种类堆栈太多，这里就只以StatusBar为例写：

0

堆栈可以看出触发是由客户端的发起跨进程addToDisplayAsUser，会触发WindowManagerService.addWindow然后方法内会勾召一个新的WindowToken
在这里插入图片描述

WindowToken加入对应的StatusBar 的WindowState

这里从堆栈也可以看出来属于addToDisplayAsUser，只不过是发生再WindowToken已经创建，及WindowState也创建后，所以它相对执行肯定较晚

android 13 WMS/AMS系统开发-SplashScreen的添加与移除分析

在系统开发过程中大家要学会怎么来学习追踪代码，这一点是非常关键的，因为在庞大系统代码中，如果什么都进行正向分析，那么很有可能因为代码过于庞大，进入分支过多而导致丢失方向，失去了主要线路，陷入一种丢了西瓜捡到芝麻情况，这情况其实经常在分析系统源码时候常见，但是这其实对我们学习主流程来说是非常不利的，因为我们往往对代码执行的主流线路都还没有摸清，没有办法对流程有一个比较好的理解，而容易被执行某个小点，小部分卡住。这里我们既可以去看一下StartingSurfaceDrawer代码，然后从它的代码开始入手分析。
