py代码：

from appium import webdriver
import time

连接移动设备所必需的参数

desired_caps = {}

当前要测试的设备的名称

desired_caps['deviceName'] = '127.0.0.1:62001'

系统

desired_caps['platformName'] = 'Android'

系统的版本

desired_caps['platformVersion'] = '7.1'

要启动app的名称(包名)

desired_caps['appPackage'] = 'com.android.settings'

要启动的app的哪个界面

desired_caps['appActivity'] = '.Settings'

driver = webdriver.Remote('http://127.0.0.1:4723/wd/hub',desired_capabilities=desired_caps)

time.sleep(10)

关闭app

driver.close_app()

释放资源

driver.quit()
