dumpsys activity containers

dumpsys activity containers

参考：

• android 13 WMS/AMS系统开发-窗口层级相关DisplayArea,WindowContainer

adb shell dumpsys activity containers可以查看当前容器层级信息

编译后的AOSP源码，在Launcher页面，运行上面的命令:

如下的例子，输出结果如下：

以上面的输出，构建层级树如下：

可见所有的Activity相关的页面，都是挂载在DefaultTaskDisplayArea下

在frameworks目录下搜索：

grep "\"DefaultTaskDisplayArea" ./ -rn

结果如下：

wz@wz:~/aosp/frameworks$ grep "\"DefaultTaskDisplayArea" ./ -rn
./base/services/core/java/com/android/server/wm/DisplayAreaPolicy.java:101:                    "DefaultTaskDisplayArea", FEATURE_DEFAULT_TASK_CONTAINER);

表示和DisplayAreaPolicy类有关
