问题描述
最近使用 airtest 和 poco 进行自动测试。由于不支持 Android-Toast ，我想使用 uiautomator2 在我的测试项目中。安装和启动都成功了。但是我得到了：
uiautomator2.exceptions.GatewayError: uiautomator2.GatewayError(gateway error,time used 0.0s)`
当我打电话时：
import uiautomator2 as u2
d = u2.connect_usb()
d.toast.show("uiautomator2",3)

似乎无法启动 uiautomator2 。python3和uiautomator2的新增功能。有人可以帮忙吗？
解决方法
经过一番努力，我发现 uiautomator2 不能与 poco 一起运行。因此，如果要同时使用它们，请先停止使用它们，再使用另一种
