Python获取android设备cpu和内存占用情况

功能：获取android设备中某一个app的cpu和内存

环境：python和adb

使用方法：使用adb连接android设备，打开将要测试的app，执行cpu/内存代码

cpu获取代码如下：（输入参数为脚本执行时间）

    get_cpu()


if __name__ == "__main__":

  tol_time = int(input("请输入脚本执行时间(分钟)："))
  start_time = time.time()
  get_applist()
  write_head()
  time_control()
  write_report()
  mapping()

会在.py文件同级目录下生成3个文件夹，config、log_su、report，其中运行结果在report中

结果以是生成折线图，看起来直观，如下：

这里我解释下，cpu占比是adb获取的实时占比，但是满值并不一定是100%，比如这张图，用的是一个八核的手机，所以CPU满值是800%

内存获取代码如下：（输入参数为脚本执行时间）
