ADB命令

首先需要配置ADB环境变量，不会的百度

1安装APK

adb install xxxx  (xxxx是你电脑apk的目录，在windwos上可以直接拖到cmd命令行)

2查看当前运行的Activity

adb shell dumpsys activity | grep -i run  

windows上需要先执行 adb shell , 然后在$后执行 dumpsys activity | grep -i run

umi:/ $ dumpsys activity | grep "mFoc"
1|umi:/ $ dumpsys activity | grep -i run
  service_reset_run_duration=60000
