[轉]adb shell dumpsys 命令
Android has an interesting command called dumpsys to dump some system information. Even described on adb manual I think that some points should be reinforced. In order to get the complete status just run (will produce a large output):
adb shell dumpsys
Also you can apply filters to running services:
| 1 SurfaceFlinger
2 accessibility 3 account 4 activity 5 alarm 6 appwidget 7 audio 8 backup 9 battery 10 batteryinfo 11 bluetooth 12 bluetooth_a2dp 13 clipboard 14 connectivity 15 content 16 cpuinfo 17 device_policy |
18 devicestoragemonitor
19 diskstats 20 dropbox 21 entropy 22 ethernet 23 hardware 24 input_method 25 iphonesubinfo 26 isms 27 keybar 28 location 29 media.audio_flinger 30 media.audio_policy 31 media.camera 32 media.player 33 meminfo 34 mount 35 netstat |
36 network_management
37 notification 38 package 39 permission 40 phone 41 power 42 search 43 sensorservice 44 simphonebook 45 statusbar 46 telephony.registry 47 throttle 48 uimode 49 usagestats 50 vibrator 51 wallpaper 52 wifi 53 window |
Some examples:
adb shell dumpsys wifi
adb shell dumpsys cpuinfo
I suggest you try other items on the list above and be creative using all the power of Unix pipes. Example, to get all memory allocated by each process you can do something like:
adb shell dumpsys meminfo | grep "allocated:" | awk '{total = total + $5}END{print total}'
adb shell dumpsys activity>d:\123.txt 還可以使用管道命令：
adb shell dumpsys activity|more
adb shell dumpsys activity|find "Running activities"
可以檢視任務棧資訊：
Running activities (most recent first):
TaskRecord{4079cc08 #14 A android.task.music}
Run #4: HistoryRecord{40723730 com.android.music/.TrackBrowserActivity}
Run #3: HistoryRecord{406dc9e0 com.android.music/.AlbumBrowserActivity}
TaskRecord{406c1708 #2 A com.android.launcher}
Run #2: HistoryRecord{406bff78 com.android.launcher/com.android.launcher2.Launcher}
TaskRecord{40777cd0 #11 A android.task.mms}
Run #1: HistoryRecord{406d0470 com.android.mms/.ui.ComposeMessageActivity}
Run #0: HistoryRecord{406cf898 com.android.mms/.ui.ConversationList}
這個命令對看Android原始碼也會有很大的幫助，因為可以看出當前手機螢幕的Activity的名稱。
dumpsys簡單介紹：該命令使用者打印出當前系統資訊，預設打印出所有service資訊，可以在命令後面加入activity引數，只打印出activity相關的資訊。
可跟引數有以下這些：
SurfaceFlinger, accessibility, account,activity, alarm, appwidget, audio, backup, battery, batteryinfo,bluetooth, bluetooth_a2dp, clipboard, connectivity, content,cpuinfo, device_policy, devicestoragemonitor, diskstats, dropbox,entropy, hardware, hdmi, input_method, iphonesubinfo, isms,location, media.audio_flinger, media.audio_policy, media.camera,media.player, meminfo, mount, netstat, network_management,notification, package, permission, phone, power, search, sensor,simphonebook, statusbar, telephony.registry, throttle, uimode,usagestats, vibrator, wallpaper, wifi, window |
在CMD下面輸入以下命令：
adb shell dumpsys activity | |
adb shell dumpsysactivity>activity.txt | “>activity.txt”是使用管道將資訊列印的activity.txt中，再使用文字編輯器開啟幫助我們更好的搜尋和分析。 |
dumpsys的引數可以跟以上資訊的名字。例如：
adb shell dumpsys activity顯示activity相關的資訊
adb shell dumpsys statusbar顯示狀態列相關的資訊
adb shell dumpsys meminfo $package_name or $pid 使用程式的包名或者程序id顯示記憶體資訊
可以通過這個命令實現很多有用的小應用，比如記憶體資訊相關的，狀態列的通知都是哪個應用談出來的等等。
我通過這個命令寫了一個小應用”找出狀態列廣告的主人“。普通通知很容易辨認是哪個應用的，廣告就不好辨認了。
其實應用就相當於一條shell命令：
adb shell dumpsys statusbar | grep notification=Notification
這條命令可以找出狀態列通知的包名，進而找到是哪個應用。

只是我把它做成了手機上應用。需要注意的是這個應用需要root許可權才能執行！
還有很多可以做的，找住對你有用的吧！
