«Кнопка Tap» дает «Неизвестная ошибка на стороне сервера при обработке команды». в Appium Android test

Question

Я запускаю SELENIUM + JAVA тест для Android-приложения с appium в первый раз. (WIndows 8.1) Я скопировал идентификатор кнопки от инспектора Appium. Я пытаюсь нажать кнопку.

isDisplayed возвращает истинный или gettext() прекрасно однако loginBtn.tap(1, 1); на кнопку дает следующее сообщение об ошибке

на затмение консоли

org.openqa.selenium.WebDriverException: An unknown server-side error occurred while processing the command.

на Appium консоли

Answer 1

Я получил это решение:

MobileElement loginBtn=androidDriver.findElementById("com.spotyo.music:id/button_login"); 
if (loginBtn.isDisplayed()){ 
    androidDriver.tap(1, loginBtn, 1);  
}
