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.

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 2 + Nice 0 + Sys 9 + Idle 22 + IOW 0 + IRQ 0 + SIRQ 0 = 33
