本文介绍了Android系统的dumpsys工具的基本用法，包括如何查看系统服务的状态和服务信息，并提供了部分命令的具体使用方法及其帮助文档的查询方式。

Android提供的dumpsys工具可以用于查看感兴趣的系统服务信息与状态，手机连接电脑后可以直接命令行执行adb shell dumpsys 查看所有支持的Service但是这样输出的太多，可以通过dumpsys | grep "DUMP OF SERVICE" 仅显示主要的Service的信息

一、列出dumpsys所有支持命令

    > adb shell  
    $ dumpsys | grep "DUMP OF SERVICE"

以下是在三星S3手机上的输出信息

    C:\Windows\System32>adb shell  
    shell@m:/ $ dumpsys | grep "DUMP OF SERVICE"

二、具体命令如何查看帮助

从上面可以看出Service非常多，“DUMP OF SERVICE”关键字后面的单词都可以直接通过 dumpsys + 单词查看相关信息，具体每一个如何使用有一种通用的查看帮助的办法。

查看每一个命令的使用帮助，以下以meminfo 为例演示：

    shell@m:/ $ dumpsys meminfo -h  
    dumpsys meminfo -h  
    meminfo dump options: [-a] [--oom] [process]  
      -a: include all available information for each process.  
      --oom: only show processes organized by oom adj.  
    If [process] is specified it can be the name or  
    pid of a specific process to dump.
