App performance test: (I) startup time

app The performance test is mainly divided into ：

Starting time ,CPU, Traffic , Electric quantity , Memory ,FPS, Over rendering

First, the startup time is analyzed ：

app The startup of is divided into cold startup （ Create... For the first time ）, Hot start （ Through the return key ,home Push the key to the background , Not completely killed ）

First, the startup time is analyzed ：

Cold start

• start-up app command

   adb shell am start -W -n  Package name /Activity name 
  

• stop it app command

   adb shell am force-stop  Package name 
  

Hot start

• start-up app The command is the same as the cold start command

    adb shell am start -W -n  Package name /Activity name 
  

• stop it app command

   adb shell input keyevent 3
  

obtain app Package name command （win10 Next ）

adb logcat | findstr "START"

Then click Start app, Can cmp=（…/…） notice app The package name and app Start page of
