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：

ACTIVITY MANAGER PENDING INTENTS (dumpsys activity intents)
  * PendingIntentRecord{42b05f20 com.android.vending startService}
  ... ... ... ...

ACTIVITY MANAGER BROADCAST STATE (dumpsys activity broadcasts)

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
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)

Running activities (most recent first):  // 最近该任务栈中活动的Activity，按最近时间排列
  TaskRecord{e0bdfdf #51 A=android.tplink.sjj.teststack U=0 StackId=4 sz=2}
    Run #1: ActivityRecord{898d92a u0 android.tplink.sjj.teststack/.FirstActivity t51}

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
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。
