查看activity的创建时��

package=com.xueqiu.android
清理缓存数据：adb shell pm clear $package
停止进程：adb shell am force-stop $package
启动app：adb shell am start  -S -W $package/.view.WelcomeActivityAlias
获取数据:
localhost:~ seveniruby$ adb logcat |grep "Displayed "

录屏+拆帧

录屏

screenrecord android自带的工具，但华为手机上没有
手机自带的录屏
摄像机独立录屏，比如很多公司的高速摄像机，不建议，设备昂贵而且自动化成本高

手机浏览器测试

webview

需要代理
需要chrome 62版本高版本在一定情况下会有bug
找一个默认开启webview debug属性的模拟器，网易mumu就不行，genymotion、as自带的模拟器是可以的
真机上需要研发配合打开debug开关
sdk版本要对

性能监控系统

生产环境注入performance api
测试环境 appium selenium execute_script 注入

课后作业1

录制自己公司app的主界面的启动过程，给出启动时间统计，并把启动过程转成git动图贴到回复里

课后作业2

找出自己的公司官网，或者学院官网https://testing-studio.com/, 加载最慢的一个资源的timing数据贴到回复里并给出说明
