Python獲取android設(shè)備cpu和內(nèi)存占用情況

更新時間：2020年11月15日 11:38:32 作者：初吻--給了奶嘴

這篇文章主要介紹了Python獲取android設(shè)備cpu和內(nèi)存占用情況，文中通過示例代碼介紹的非常詳細(xì)，對大家的學(xué)習(xí)或者工作具有一定的參考學(xué)習(xí)價值，需要的朋友們下面隨著小編來一起學(xué)習(xí)學(xué)習(xí)吧

功能：獲取android設(shè)備中某一個app的cpu和內(nèi)存

環(huán)境：python和adb

使用方法：使用adb連接android設(shè)備，打開將要測試的app，執(zhí)行cpu/內(nèi)存代碼

cpu獲取代碼如下：（輸入?yún)?shù)為腳本執(zhí)行時間）

會在.py文件同級目錄下生成3個文件夾，config、log_su、report，其中運行結(jié)果在report中

結(jié)果以是生成折線圖，看起來直觀，如下：

這里我解釋下，cpu占比是adb獲取的實時占比，但是滿值并不一定是100%，比如這張圖，用的是一個八核的手機(jī)，所以CPU滿值是800%
