问题描述

我正在 Android Mobile 的 chrome 浏览器中自动化一个网络应用程序.我有 7.0 版的 ADV

我正在尝试使用以下代码发送用于登录的用户名 -

driver = new AppiumDriver(new URL("http://0.0.0.0:4723/wd/hub"), capabilities);driver.manage().timeouts().implicitlyWait(60, TimeUnit.SECONDS);driver.get("https://site-url/");driver.findElement(By.id("email")).sendKeys("[e-mail]")

I'm automating a web app in chrome browser in Android Mobile. I've ADV with version 7.0

I'm trying to send user name for login using below code -

Note: please don't mark it as duplicate. solution from below references are not working for me.

1. org.openqa.selenium.WebDriverException: unknown error: call function result missing 'value'

2. Selenium WebDriverException: unknown error: call function result missing 'value' while calling sendkeys method

I'm using latest chrome version i.e. 71 and chromedriver 2.45 . It doesn't seems a compatibility issue.

Observation : chromedriver version 2.45 used to set property but it shows chromedriver=2.33.506120 in exception

解决方案

This seems default Appium's chromedriver.exe issue in my case as it was taking chromedriver=2.33.506120 by default even i have set 2.45 version. following workaround resolved my issue.

Prerequisites Should have compatible chromedriver.exe version with the chrome version installed in device/emulator

setting chromedriver.exe path in Appium using System.setProperty("webdriver.chrome.driver", "D:\\Eclipse\\chromedriver.exe"); won't work

Use following ways to set chromedriver path in Appium:

1. Using DesiredCapabilities e.g.

   DesiredCapabilities capabilities = new DesiredCapabilities();
   capabilities.setCapability("platformName", "Android");
   capabilities.setCapability("deviceName", "emulator-5554 (9)");
   capabilities.setCapability("platformVersion", "9");
   capabilities.setCapability("browserName", "Chrome");
   capabilities.setCapability("noReset", true);
   capabilities.setCapability("chromedriverExecutable", "D:\\chromedriver_win32_2.45\\chromedriver.exe");
   

2. Provide chromedriver.exe path while start Appium Server. Refer below snap
