Android dumpSys命令用法总结

dumpsys命令对于Android开发者来说是必备技能，它能够dump系统服务的各种状态，在我们开发调试中起到了很重要的作用

1.dumpsys服务列表

不同的Android系统版本支持的命令有所不同，可通过下面命令查看当前手机所支持的dump服务

dumpsys -l

这些服务名或许你并看不出其调用的哪个服务，那么这时可以通过下面指令：service list。

130|[email protected]_x86_64:/ # dumpsys -lCurrently running services:  DockObserver  SurfaceFlinger  accessibility  account  activity  alarm  android.security.keystore  appops  appwidget  assetatlas  audio  backup  battery  batteryproperties  batterystats  clipboard  commontime_management  connectivity  consumer_ir  content  country_detector  cpuinfo  dbinfo  device_policy  devicestoragemonitor  diskstats  display  dreams  drm.drmManager  dropbox  entropy  fingerprint  gfxinfo  hardware  imms  input  input_method  iphonesubinfo  isms  isub  jobscheduler  launcherapps  location  lock_settings  media.audio_flinger  media.audio_policy  media.camera  media.player  media.sound_trigger_hw  media_projection  media_router  media_session  meminfo  mount  netpolicy  netstats  network_management  network_score  notification  package  permission  phone  power  print  procstats  restrictions  rttmanager  samplingprofiler  scheduling_policy  search  sensorservice  serial  servicediscovery  simphonebook  statusbar  telecom  telephony.registry  textservices  trust  uimode  updatelock  usagestats  usb  user  vibrator  voiceinteraction  wallpaper  webviewupdate  wifi  wifip2p  wifiscanner  window

以上是当前系统dumpsys支持的服务列表，可以通过 dumpsys [服务名] -h 的方法来查看每一个服务的使用方法

比如我们查看 dumpsys activity 的使用方法

dumpsys activity -h

[email protected]_x86_64:/ # dumpsys activity -hActivity manager dump options:  [-a] [-c] [-p package] [-h] [cmd] ...  cmd may be one of:    a[ctivities]: activity stack state    r[recents]: recent activities state    b[roadcasts] [PACKAGE_NAME] [history [-s]]: broadcast state    i[ntents] [PACKAGE_NAME]: pending intent state    p[rocesses] [PACKAGE_NAME]: process state    o[om]: out of memory management    prov[iders] [COMP_SPEC ...]: content provider state    provider [COMP_SPEC]: provider client-side state    s[ervices] [COMP_SPEC ...]: service state    as[sociations]: tracked app associations    service [COMP_SPEC]: service client-side state    package [PACKAGE_NAME]: all state related to given package    all: dump all activities    top: dump the top activity    write: write all pending state to storage    track-associations: enable association tracking    untrack-associations: disable and clear association tracking  cmd may also be a COMP_SPEC to dump activities.  COMP_SPEC may be a component name (com.foo/.myApp),    a partial substring in a component name, a    hex object identifier.  -a: include all available server state.  -c: include client state.  -p: limit output to given package.

2.dumpsys activity

查看当前APP的Service状态

dumpsys activity s 包名

查看当前APP的广播状态

dumpsys activity b 包名

查看当前APP的进程状态

dumpsys activity p 包名

查看当前APP的Activity状态

dumpsys activity a 包名

dumpsys activity根据后面跟着的不同参数则输出相应的内容，当不跟任何参数， dumpsys activity等价于依次输出下面8条命令：

dumpsys activity intentsdumpsys activity broadcasts //广播dumpsys activity providers  //providerdumpsys activity permissionsdumpsys activity services  //服务dumpsys activity recentsdumpsys activity activities //activitydumpsys activity processes
