Android App性能測試之2：啓動時間

獲取啓動時間步驟：

一、設置sdk+python環境

 

二、爲了獲取App的包（package）名，在cmd輸入adb logcat | grep START啓動監控指令

 

三、打開App，在cmd查看新增的記錄中尋找cmp="com.xxxxx"/.xxxx.xxxActivity，引號裏是包名

 

四、輸入啓動App命令adb shell am start -W -n package/activity，ThisTime的值就是啓動時間

 

五、輸入中止App命令adb shell am force-stop package（注意：沒有activity），這時App退出——冷啓動

#五、輸入退到後臺命令adb shell input keyevent 3，至關於Back或Home鍵暫停App（退到後臺）——熱啓動

 

六、重複10次，取除了第1個的時間以外的9個值取平均值作圖表分析
