Android查看app内存和cpu占用

1.可以使用adb shell showmap pid查看一个进程的showmap，这对于我们来说非常有用，可以确定进程中哪些库占用内存比较多 1,确定app进程号,通过jarvis过滤,ps-A显示全部进程

ps命令使用 cmd通过adb shell进入与移动设备的命令交互界面。然后使用ps指令，最常用的是ps -aux和ps -ef与grep混合用，筛选要查找的进程信息ps -ef|grep "筛选的进程字符" adb shell ps|more 显示全部进程信息(加|more为了分页显示)

筛选需要的进程信息 adb shell ps -ef |findstr "筛选进程信息" ps: adb shell ps -ef |findstr "baidu"

g6sa:/ # ps -A | grep jarvis ps -A | grep jarvis u0_a37 21979 2223 3858620 193980 SyS_epoll_wait 0 S cn.alios.jarvisd u0_a47 22750 2223 3829168 172756 SyS_epoll_wait 0 S com.ebanma.jarvis 2,showmap

可以通过adb shell showmap 22750 > log7.txt 将info保存到日志里

也可查看占用cpu最高的前10个程序（-t 显示进程名称，-s 按指定行排序，-n 在退出前刷新几次，-d 刷新间隔，-m 显示最大数量）： top -m 10 -s 9 (数字9代表按照cpu占用率排序,-s后面只能跟数字)

做cpu占用率测试时需要执行一些命令辅助我们测试,比如每隔500ms发一次广播,可以借助脚本:

while true do adb shell am broadcast -a android.intent.action.openTinyAppp -e data datavalue sleep 0.5s echo '+++++++++++++++++++' done
