Недавно работал над автоматическим тестированием с использованием airtest и poco.Из-за того, что Android-Toast не поддерживается, я хочу использовать uiautomator2 в моем проекте тестирования.Установка, а также инициализация завершаются успешно.Но я получил:

 uiautomator2.exceptions.GatewayError: uiautomator2.GatewayError(gateway error, time used 0.0s)` 
  

когда я вызываю:

 import uiautomator2 as u2
d = u2.connect_usb()
d.toast.show("uiautomator2", 3)
  

Полная трассировка стека:

Кажется, uiautomator2 не может быть запущен.Новое в python3 и uiautomator2. Кто-нибудь может помочь?

После некоторой напряженной работы я обнаружил, что uiautomator2 просто не может работать с poco вместе.Поэтому, если вы хотите использовать их оба, остановите один, прежде чем использовать другой.
