Android 性能分析工具dumpsys的使用(自己增加一部分在后面)

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

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:
1
2
3
4
5
6
7
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.

三、一些关键命令解释


名字功能
account 显示accounts信息
activity 显示所有的activities的信息
cpuinfo显示CPU信息
window显示键盘,窗口和它们的关系
wifi 显示wifi信息
batteryinfo $package_name电量信息及CPU 使用时长
package packagename获取安装包信息
usagestats每个界面启动的时间
statusbar显示状态栏相关的信息
meminfo
内存信息(meminfo $package_name or $pid 
使用程序的包名或者进程id显示内存信息)
diskstats 磁盘相关信息
battery 电池信息
alarm显示Alarm信息
  

    dumpsys statusbar | grep notification=Notification 


也可以单独列出某个系统服务的,比如battery,命令:dumpsys battery,如果想知道具体可以做哪些操作可:dumpsys battery -h来查看,比如我们想设置电量百分比,可以

dumpsys battery set level 5。
