android技巧：dumpsys簡化資訊檢視Activity結構

阿新 • • 發佈：2021-01-17

技術標籤：android

一般獲取Activity棧結構都是通過dumpsys去獲取，但是內容實在太多

比如通過adb shell dumpsys activity activities 檢視結果如下：

ACTIVITY MANAGER ACTIVITIES (dumpsys activity activities)
Display #0 (activities from top to bottom):

  Stack #1: type=standard mode=fullscreen

這裡麵包含了太多資訊，包括意圖、資料、適配、背景等等，實際上大多情況下我們只需要關注我們的棧結構以及Activity的順序是否達到了我們的預期

解決方案

1. 簡要資訊

因此可以藉助grep來完成最終效果
首先進入android手機終端

adb shell

然後通過dumpsys列印資訊，並通過grep查詢Hist相關資訊即可。

dumpsys activity activities|grep Hist

最終獲取結果如下：

      * Hist #3: ActivityRecord{ccbcbb8 u0 com.craaaaazy.test3/.LaunchMode3 t165}
          keysPaused=false inHistory=true visible=true sleeping=false idle=true mStartingWindowState=STARTING_WINDOW_NOT_SHOWN
      * Hist #2: ActivityRecord{bae469c u0 com.craaaaazy.test3/.LaunchMode2 t165}
          keysPaused=false inHistory=true visible=false sleeping=false idle=true mStartingWindowState=STARTING_WINDOW_NOT_SHOWN
      * Hist #1: ActivityRecord{998e67d u0 com.craaaaazy.test3/.LaunchMode1 t165}
          keysPaused=false inHistory=true visible=false sleeping=false idle=true mStartingWindowState=STARTING_WINDOW_NOT_SHOWN
      * Hist #0: ActivityRecord{270f455 u0 com.craaaaazy.test3/.MainActivity t165}
          keysPaused=false inHistory=true visible=false sleeping=false idle=true mStartingWindowState=STARTING_WINDOW_REMOVED
      * Hist #0: ActivityRecord{79ba14e u0 com.android.launcher3/.Launcher t2}
          keysPaused=false inHistory=true visible=false sleeping=false idle=true mStartingWindowState=STARTING_WINDOW_NOT_SHOWN

資訊簡潔明瞭，便於快速分析

2. 包含Stack/TaskRecord的簡明資訊

上面資訊雖然簡明，但是隻是羅列了Activity的順序，看不出是分別在哪個對應的棧中，可以用正則的方式過濾資訊，如下：

dumpsys activity activities|grep -E 'Stack|TaskRecord|Hist'

通過-E，過濾出Stack棧順序和結構、TaskRecord任務的順序和結構以及Activity的順序，如下：

  Stack #7: type=standard mode=fullscreen
    * TaskRecord{569e404 #170 A=com.android.gallery3d U=0 StackId=7 sz=1}
      * Hist #0: ActivityRecord{40b516b u0 com.android.gallery3d/.app.GalleryActivity t170}
          frontOfTask=true task=TaskRecord{569e404 #170 A=com.android.gallery3d U=0 StackId=7 sz=1}
          keysPaused=false inHistory=true visible=true sleeping=false idle=true mStartingWindowState=STARTING_WINDOW_SHOWN
      TaskRecord{569e404 #170 A=com.android.gallery3d U=0 StackId=7 sz=1}
  Stack #0: type=home mode=fullscreen
    * TaskRecord{4d9dfb9 #2 I=com.android.launcher3/.Launcher U=0 StackId=0 sz=1}
      * Hist #0: ActivityRecord{79ba14e u0 com.android.launcher3/.Launcher t2}
          frontOfTask=true task=TaskRecord{4d9dfb9 #2 I=com.android.launcher3/.Launcher U=0 StackId=0 sz=1}
          keysPaused=false inHistory=true visible=false sleeping=false idle=true mStartingWindowState=STARTING_WINDOW_NOT_SHOWN
      TaskRecord{4d9dfb9 #2 I=com.android.launcher3/.Launcher U=0 StackId=0 sz=1}
  Stack #6: type=standard mode=fullscreen
    * TaskRecord{ff20a25 #169 A=com.craaaaazy.test3 U=0 StackId=6 sz=1}
      * Hist #0: ActivityRecord{33a8d8e u0 com.craaaaazy.test3/.LaunchMode3 t169}
          frontOfTask=true task=TaskRecord{ff20a25 #169 A=com.craaaaazy.test3 U=0 StackId=6 sz=1}
          keysPaused=false inHistory=true visible=false sleeping=false idle=true mStartingWindowState=STARTING_WINDOW_REMOVED
      TaskRecord{ff20a25 #169 A=com.craaaaazy.test3 U=0 StackId=6 sz=1}
  Stack #4: type=standard mode=fullscreen
    * TaskRecord{61281c2 #168 A=com.craaaaazy.test3 U=0 StackId=4 sz=3}
      * Hist #2: ActivityRecord{1de3363 u0 com.craaaaazy.test3/.LaunchMode2 t168}
          frontOfTask=false task=TaskRecord{61281c2 #168 A=com.craaaaazy.test3 U=0 StackId=4 sz=3}
          keysPaused=false inHistory=true visible=false sleeping=false idle=true mStartingWindowState=STARTING_WINDOW_NOT_SHOWN
      * Hist #1: ActivityRecord{4460310 u0 com.craaaaazy.test3/.LaunchMode1 t168}
          frontOfTask=false task=TaskRecord{61281c2 #168 A=com.craaaaazy.test3 U=0 StackId=4 sz=3}
          keysPaused=false inHistory=true visible=false sleeping=false idle=true mStartingWindowState=STARTING_WINDOW_REMOVED
      * Hist #0: ActivityRecord{110404f u0 com.craaaaazy.test3/.MainActivity t168}
          frontOfTask=true task=TaskRecord{61281c2 #168 A=com.craaaaazy.test3 U=0 StackId=4 sz=3}
          keysPaused=false inHistory=true visible=false sleeping=false idle=true mStartingWindowState=STARTING_WINDOW_REMOVED
      TaskRecord{61281c2 #168 A=com.craaaaazy.test3 U=0 StackId=4 sz=3}
  mFocusedStack=ActivityStack{a77ded stackId=7 type=standard mode=fullscreen visible=true translucent=false, 1 tasks} mLastFocusedStack=ActivityStack{a77ded stackId=7 type=standard mode=fullscreen visible=true
translucent=false, 1 tasks}
  mUserStackInFront={}
   mHomeStack=ActivityStack{430e0d6 stackId=0 type=home mode=fullscreen visible=false translucent=true, 1 tasks}

這樣再去分析就可以忽略很多不必要的內容，一目瞭然。
同樣的方法，可以用來簡化dumpsys支援的其他資訊~
