一、用到的adb命令
(1)查看activity:
adb shell dumpsys window | findstr mCurrentFocusadb shell dumpsys activity activities
(2)启动app:
adb shell am start -W -n package/activity
(3)停止app:
adb shell am force-stop package
(4)home退出app:
adb shell input keyevent 3
二、脚本实现策略
策略一:获取命令执行时间,作为启动时间参考值,比较好实现。
策略二:在命令前后加上时间戳,以差值作为参考值,比较准确。
三、测试数据分析
一般剔除第一次数据,取剩余次数数据进行分析,因为第一次往往不准确。
(1)均值。
(2)曲线的波动范围。
(3)不同版本对比。
(4)和竞品对比。
四、代码实现示例
(1)冷启动
