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

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
doadb shell am broadcast -a android.intent.action.openTinyAppp -e data datavaluesleep 0.5secho '+++++++++++++++++++'
done
