adb shell am [command]
am =>是activity manager的缩写,它可以启动activity,启动service,发送广播等 pm =>就是package manager的缩写.
发送一条广播
adb -s BH909NJ676 shell am broadcast
adb 获取内存占用
adb shell dumpsys meminfo -h
meminfo dump options: [-a] [-d] [-c] [-s] [--oom] [process]
-a: include all available information for each process.
-d: include dalvik details.
-c: dump in a compact machine-parseable representation.
-s: dump only summary of application memory usage.
-S: dump also SwapPss.
--oom: only show processes organized by oom adj.
--local: only collect details locally, don't call process.
--package: interpret process arg as package, dumping all
processes that have loaded that package.
--checkin: dump data for a checkin
If [process] is specified it can be the name or
pid of a specific process to dump.

adb 获取cpu占用
直接去获取信息占用比例
adb shell dumpsys cpuinfo
如果获取对应某个app 包名占用需要用到
adb shell top -m 10 -n 1 -s cpu
User 6%, System 27%, IOW 0%, IRQ 0%
User 2 + Nice 0 + Sys 9 + Idle 22 + IOW 0 + IRQ 0 + SIRQ 0 = 33
