adb命令查看 activity列表

根据上面的介绍，可以得知，我们可以使用如下的脚本，adb shell dumpsys activity activities

运行后，得到有如下结构的日志信息：Stack #45: type=standard mode=fullscreen

isSleeping=false

mBounds=Rect(0, 0 - 0, 0)

......

Stack #0: type=home mode=fullscreen

isSleeping=false

mBounds=Rect(0, 0 - 0, 0)

......

Stack #1: type=recents mode=fullscreen

isSleeping=false

mBounds=Rect(0, 0 - 0, 0)

......

其中每个Stack开始代表一个App的活动栈，每个活动栈有一个id，如上所示的Stack #45中的45。

android系统中目前定义了两种类型的Stack，系统预定义的静态栈，总共有五种，如下所示：0 HOME_STACK_ID：Home应用以及recents app所在的栈

1 FULLSCREEN_WORKSPACE_STACK_ID：一般应用所在的栈

2 FREEFORM_WORKSPACE_STACK_ID：类似桌面操作系统

3 DOCKED_STACK_ID：分屏

4 PINNED_STACK_ID：画中画栈

另一种栈，是系统动态生成的，它的id就是大于4

我们来看下Stack块中的内容，我们随机抽取了一个stack进行分析Stack #4: type=standard mode=fullscreen //Stack信息

isSleeping=false

mBounds=Rect(0, 0 - 0, 0)

Task id #51 //Task信息

mBounds=Rect(0, 0 - 0, 0)

mMinWidth=-1

mMinHeight=-1

mLastNonFullscreenBounds=null

mLastPausedActivity: ActivityRecord{4542de6 u0 android.tplink.sjj.teststack/.MainActivity t51} //最后一个退出前台的Activity

..........................

以上内容中，我们可以找到如下的关键词，Running activities (most recent first):

该关键词表示是该Stack中正在运行的activity列表，并且按照时间最近排序，第一个为最顶层的ActivitymResumedActivity

该关键词后表示的就是当前正在运行的ActivitymLastPausedActivity

该关键词后表示的就是最近一个退出前台的Activity

快捷查看所有当前正在运行的Activity

如果我们觉得上面的信息太冗杂，不需要这么详尽的信息，那么我们还有如下的命令进行过滤adb shell dumpsys activtiy activities | sed -En -e '/Running activities/,Run #0/p'

同理其他的组件，比如Intent、Service等。
