adb打印activity堆栈

使用adb查看当前手机的相关内容

adb shell dumpsys activity

可以得到如下内容:

每部分的开头部分,都会显示 如果想要查看哪些内容,需要使用哪些命令

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,

db 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

Running activities (most recent first):  // 最近该任务栈中活动的Activity,按最近时间排列

    Run #1: ActivityRecord{898d92a u0 android.tplink.sjj.teststack/.FirstActivity t51}

mResumedActivity: ActivityRecord{898d92a u0 android.tplink.sjj.teststack/.FirstActivity t51}   //当前页面Activity
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Activity

mResumedActivity 

该关键词后表示的就是当前正在运行的Activity

mLastPausedActivity

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 activity activities | sed -En -e '/Running activities/,Run #0/p'

同理其他的组件,比如Intent、Service等。
