以下是打开应用的代码（python）。如果操作对象是系统应用，代码正常运行；如果操作的对象为用户安装的应用，代码报错
from appium import webdriver
desired_caps = dict()
#平台名：区分Android、ios
desired_caps['platformName'] = 'Android'
#平台版本：同连接设备上的（关于）安卓版本一致 （6.1.1版本，可填写6.1.1、6.1、6）
desired_caps['platformVersion'] = '9'
#设备名：ios需正确填写，安卓不为空则可以
desired_caps['deviceName'] = 'CLB7N18301000651'
#应用名：通过adb查看
desired_caps['appPackage'] = 'com.lefull.tenant'
#界面名：通过adb查看
desired_caps['appActivity'] = '.ui.TenantActivity'
#打开应用，进入指定页面
driver = webdriver.Remote('http://127.0.0.1:4723/wd/hub', desired_caps)
运行非系统应用，代码报错

在网络上查资料，发现全部的测试安卓系统都是5。如果想测试安卓7以上的系统，应该如何解决？？？
谢谢！！
