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。

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

root@generic_x86_64:/ # dumpsys activity -h
Activity 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 intents
dumpsys activity broadcasts //广播
dumpsys activity providers  //provider
dumpsys activity permissions
dumpsys activity services  //服务
dumpsys activity recents
dumpsys activity activities //activity
dumpsys activity processes
