Android 实时监控CPU、MEM、FPS、NET信息

1、需求
在用户操作手机时（或模拟用户操作手机），实时检测手机CPU、FPS、MEM、NET信息，确实此数据变化是否异常
2、环境
Win7+Python3+Appium
3、代码目录说明
image
4、运行方式
4.1 连接手机，并导入相关第三方库(pip )
image
4.2 修改全局变量PACKAGE_NAME、ACTIVITY_NAME的值（即确认被测应用的包名和类名）
image
4.3 重写User类的user_swipe_screen()方法，为读取设备相关信息做准备
4.4 运行main函数，并输入模拟用户操作的次数
image
5、结果说明
5.1 测试完成后，会在main.py同级目录生成下面文件
image
5.2 可以打开csv文件并插入折线图
