I'm looking for the full list of ADB shell
dumpsys commands with a full explanation of all of the commands.
Where can I find this information?
What's dumpsys and what are its benefit
dumpsys is an android tool that runs on the device and dumps interesting information about the status of system services.
- Possibility to easily get system information in a simple string representation.
- Possibility to use dumped CPU, RAM, Battery, storage stats for a pretty charts, which will allow you to check how your application affects the overall device!
What information can we retrieve from dumpsys shell command and how we can use it
If you run dumpsys you would see a ton of system information. But you can use only separate parts of this big dump.
to see all of the "subcommands" of dumpsys do:
dumpsys | grep "DUMP OF SERVICE"
DUMP OF SERVICE SurfaceFlinger: DUMP OF SERVICE accessibility: DUMP OF SERVICE account: DUMP OF SERVICE activity: DUMP OF SERVICE alarm: DUMP OF SERVICE appwidget: DUMP OF SERVICE audio: DUMP OF SERVICE backup: DUMP OF SERVICE battery: DUMP OF SERVICE batteryinfo: DUMP OF SERVICE clipboard: DUMP OF SERVICE connectivity: DUMP OF SERVICE content: DUMP OF SERVICE cpuinfo: DUMP OF SERVICE device_policy: DUMP OF SERVICE devicestoragemonitor: DUMP OF SERVICE diskstats: DUMP OF SERVICE dropbox: DUMP OF SERVICE entropy: DUMP OF SERVICE hardware: DUMP OF SERVICE input_method: DUMP OF SERVICE iphonesubinfo: DUMP OF SERVICE isms: DUMP OF SERVICE location: DUMP OF SERVICE media.audio_flinger: DUMP OF SERVICE media.audio_policy: DUMP OF SERVICE media.player: DUMP OF SERVICE meminfo: DUMP OF SERVICE mount: DUMP OF SERVICE netstat: DUMP OF SERVICE network_management: DUMP OF SERVICE notification: DUMP OF SERVICE package: DUMP OF SERVICE permission: DUMP OF SERVICE phone: DUMP OF SERVICE power: DUMP OF SERVICE reboot: DUMP OF SERVICE screenshot: DUMP OF SERVICE search: DUMP OF SERVICE sensor: DUMP OF SERVICE simphonebook: DUMP OF SERVICE statusbar: DUMP OF SERVICE telephony.registry: DUMP OF SERVICE throttle: DUMP OF SERVICE usagestats: DUMP OF SERVICE vibrator: DUMP OF SERVICE wallpaper: DUMP OF SERVICE wifi: DUMP OF SERVICE window:
Some Dumping examples and output
1) Getting all possible battery statistic:
$~ adb shell dumpsys battery
You will get output:
Current Battery Service state: AC powered: false AC capacity: 500000 USB powered: true status: 5 health: 2 present: true level: 100 scale: 100 voltage:4201 temperature: 271 <---------- Battery temperature! %) technology: Li-poly <---------- Battery technology! %)
2)Getting wifi informations
~$ adb shell dumpsys wifi
Wi-Fi is enabled Stay-awake conditions: 3 Internal state: interface tiwlan0 runState=Running SSID: XXXXXXX BSSID: xx:xx:xx:xx:xx:xx, MAC: xx:xx:xx:xx:xx:xx, Supplicant state: COMPLETED, RSSI: -60, Link speed: 54, Net ID: 2, security: 0, idStr: null ipaddr 192.168.1.xxx gateway 192.168.x.x netmask 255.255.255.0 dns1 192.168.x.x dns2 220.127.116.11 DHCP server 192.168.x.x lease 604800 seconds haveIpAddress=true, obtainingIpAddress=false, scanModeActive=false lastSignalLevel=2, explicitlyDisabled=false Latest scan results: Locks acquired: 28 full, 0 scan Locks released: 28 full, 0 scan Locks held:
3) Getting CPU info
~$ adb shell dumpsys cpuinfo
Load: 0.08 / 0.4 / 0.64 CPU usage from 42816ms to 34683ms ago: system_server: 1% = 1% user + 0% kernel / faults: 16 minor kdebuglog.sh: 0% = 0% user + 0% kernel / faults: 160 minor tiwlan_wq: 0% = 0% user + 0% kernel usb_mass_storag: 0% = 0% user + 0% kernel pvr_workqueue: 0% = 0% user + 0% kernel +sleep: 0% = 0% user + 0% kernel +sleep: 0% = 0% user + 0% kernel TOTAL: 6% = 1% user + 3% kernel + 0% irq
4)Getting memory usage informations
~$ adb shell dumpsys meminfo 'your apps package name'
** MEMINFO in pid 5527 [com.sec.android.widgetapp.weatherclock] ** native dalvik other total size: 2868 5767 N/A 8635 allocated: 2861 2891 N/A 5752 free: 6 2876 N/A 2882 (Pss): 532 80 2479 3091 (shared dirty): 932 2004 6060 8996 (priv dirty): 512 36 1872 2420 Objects Views: 0 ViewRoots: 0 AppContexts: 0 Activities: 0 Assets: 3 AssetManagers: 3 Local Binders: 2 Proxy Binders: 8 Death Recipients: 0 OpenSSL Sockets: 0 SQL heap: 0 MEMORY_USED: 0 PAGECACHE_OVERFLOW: 0 MALLOC_SIZE: 0
If you want see the info for all processes, use
~$ adb shell dumpsys meminfo
dumpsys is ultimately flexible and useful tool!
If you want to use this tool do not forget to add permission into your android manifest automatically
Try to test all commands to learn more about dumpsys. Happy dumping!
adb shell service -l
You can then supply the service name you are interested in to dumpsys to get the specific information. For example (note that not all services provide dump info):
adb shell dumpsys activity adb shell dumpsys cpuinfo adb shell dumpsys battery
As you can see in the code (and in K_Anas's answer), if you call dumpsys without any service name, it will dump the info on all services in one big dump:
adb shell dumpsys
Some services can receive additional arguments on what to show which normally is explained if you supplied a
-h argument, for example:
adb shell dumpsys activity -h adb shell dumpsys window -h adb shell dumpsys meminfo -h adb shell dumpsys package -h adb shell dumpsys batteryinfo -h
According to official Android information about dumpsys:
The dumpsys tool runs on the device and provides information about the status of system services.
To get a list of available services use
adb shell dumpsys -l
I use dumpsys to catch if an app is crashed and process is still active. The situation I used it for is to find about remote machine app is crashed or not.
dumpsys | grep myapp | grep "Application Error"
adb shell dumpsys | grep myapp | grep Error
or anything that helps... etc.
If the app is not running you will get nothing as a result. When app is stopped a message is shown on screen by Android, process is still active and if you check via "ps" command or anything else, you will see process state is not showing any error or crash meaning. But when you click button to close message, app process will cleaned from process list. so catching crash state without any code in application is hard to find. but dumpsys helps you.
