一、dumpsys命令介紹
1.命令說明
Dumpsys用戶系統診斷,它運行在設備上,並提供系統服務狀態信息
命令格式: adb shell dumpsys [system serbices]
2.系統服務查詢
如果直接運行adb shell dumpsys,將會獲得所有的系統服務信息,那是非常多的,為了更容易管理輸出,可以指定你想要檢查的服務,例如:
adb shell dumpsys –l
adb shell serverce list
#都是查看有哪些系統服務(需要哪些服務就指定哪些服務)
命令行參數:
不同的服務有不同的選項,一下兩個是常見的參數:
-h:對於大多數的服務,可以添加-h看到文本的幫助
-c:對於一些服務,可以添加-c查看數據會更友好
例如:
adb shell dumpsys meminfo –h

六、用法補充
出發點一:
Android 引入了「任務棧」的概念,這個概念對於 Android 設備上的返回按鍵有極其重要的聯系。有時候按下返回按鈕或者點擊關閉當前 Activity 的操作,都不知道 Android 系統會把程序帶到哪個 Activity ,不確定這是否是最後一個 Activity 以致退出了整個程序。亦或者一些按鈕和操作循環產生 Activity 而造成內存膨脹。對於這些問題,如果能夠在調試期間知道當前任務棧的情況,就能很方便的觀察和發現問題存在的原因,進而選擇正確的 launchMode ,設置且當 Intent 的 Flag 來使程序達到預期的效果。
出發點二:
手機裏裝著一個應用,在不反編譯也不做其他處理的情況下,你可以對這個應用了解多少。
出發點三:「出自官方文檔」
dumpsys is a tool that runs on Android devices and provides information about system services. You can call dumpsys from the command line using the Android Debug Bridge (ADB) to get diagnostic output for all system services running on a connected device. This output is typically more verbose than you may want, so use the command line options described below to get output for only the system services you‘re interested in. This page also describes how to use dumpsys to accomplish common tasks, such as inspecting input, RAM, battery, or network diagnostics.
命令格式:
adb shell dumpsys activity [options] [WHAT]

options | 含義 |
---|---|
-a | 包括所有可用 Servier 狀態 |
-c | 包括 Client 狀態,即 App 端情況 |
-p PACKAGE | 限定輸出指定包名 |

a[ctivities] | activity 狀態 |
b[roadcasts] [PACKAGE_NAME] | broadcast 狀態 |
s[ervices] [COMP_SPEC ...] | service 狀態 |

開始練習
練習一:
輸入:
adb shell dumpsys activity
輸出:
ACTIVITY MANAGER PENDING INTENTS (dumpsys activity intents) //註意一下
* PendingIntentRecord{1004eb1 com.tencent.mobileqq broadcastIntent}
* PendingIntentRecord{a9858c7 com.google.android.gms broadcastIntent}
* PendingIntentRecord{dc3ae3d com.tencent.mm startService}
// 省略 N 行 ...
ACTIVITY MANAGER BROADCAST STATE (dumpsys activity broadcasts) //註意一下
Historical broadcasts [foreground]:
#0: BroadcastRecord{63c6dd9 u-1 android.hardware.usb.action.USB_STATE}
// 省略 N 行 ...
ACTIVITY MANAGER CONTENT PROVIDERS (dumpsys activity providers) //註意一下
Published single-user content providers (by class):
* ContentProviderRecord{ef6fc1f u0 com.android.providers.telephony/.TelephonyProvider}
proc=ProcessRecord{efab720 3684:com.android.phone/1001}
singleton=true
authority=telephony
// 省略 N 行 ...
ACTIVITY MANAGER URI PERMISSIONS (dumpsys activity permissions) //註意一下
Granted Uri Permissions:
* UID 10129 holds:
UriPermission{b827fb4 0 @ content://downloads/all_downloads/125}
UriPermission{2b167dd 0 @ content://downloads/all_downloads/134}
UriPermission{51cbf52 0 @ content://downloads/all_downloads/148}
UriPermission{af4a223 0 @ content://downloads/all_downloads/169}
ACTIVITY MANAGER SERVICES (dumpsys activity services) //註意一下
User 0 active services:
* ServiceRecord{da1e320 u0 com.android.bluetooth/.hid.HidService}
app=null
created=-12d3h35m44s197ms started=false connections=1
// 省略 N 行 ...
ACTIVITY MANAGER RECENT TASKS (dumpsys activity recents) //註意一下
Recent tasks:
* Recent #0: TaskRecord{162657c #917 A=android.task.mms U=0 sz=1}
// 省略 N 行 ...
ACTIVITY MANAGER ACTIVITIES (dumpsys activity activities) //註意一下
Display #0 (activities from top to bottom):
// 省略 N 行 ...
ACTIVITY MANAGER RUNNING PROCESSES (dumpsys activity processes) //註意一下
Isolated process list (sorted by uid):
Isolated # 0: ProcessRecord{ffa12e5 3187:WebViewLoader-arm64-v8a/1037}
UID states:
UID 1000: UidRecord{15a01ba 1000 P / 19 procs}
// 省略 N 行 ...
上面標註「註意一下」的位置,其實是提示可以使用括號中的命令來獲取此部分對應的內容:
所以「adb shell dumpsys activity」命令等價於依次輸出下面 8 條命令:
adb shell dumpsys activity intents //主要輸出 PendingIntentRecord
adb shell dumpsys activity broadcasts
adb shell dumpsys activity providers// Published single-user content providers (by class) / Published user 0 content providers (by class) /
adb shell dumpsys activity permissions
adb shell dumpsys activity services
adb shell dumpsys activity recents
adb shell dumpsys activity activities
adb shell dumpsys activity processes
練習二:
輸入:
adb shell dumpsys activity top
輸出:
TASK com.jianshu.haruki id=101
ACTIVITY com.jianshu.haruki/com.baiji.jianshu.MainActivity fb571c1 pid=21291
// ... 只舉出了前兩行,省略了 N 行代碼
獲取當前 Android 系統中與用戶交互的 Activity 的詳細信息,根據輸出可得到簡書的應用包名是:「com.jianshu .haruki」
練習三:
輸入:
adb shell dumpsys activity activities
意義:
顯示當前所有在運行的任務棧,它們的 id 分別是什麽。對於每個 Task 也有 Activity 數量等信息,同時也列出了其中的 Activity 列表,並且對於每個 Activity 也有比較詳細的描述,比如啟動它的 Intent 的內容。如果覺得內容過多,只想看看棧的內容,也可以直接跳到「Running activities (most recent first) 那部分,比較簡潔而又明了的列出了棧中的 Activity 列表,就能知道當按下返回鍵的時候會應該回到哪個 Activity 」
