Hi there,
I am having an issue while running the following code,it’s throwing
“Exception in thread “main” java.lang.ClassCastException: class java.util.ArrayList cannot be cast to class io.appium.java_client.MobileElement (java.util.ArrayList is in module java.base of loader ‘bootstrap’; io.appium.java_client.MobileElement is in unnamed module of loader ‘app’)
at appium.AppiumTest.main(AppiumTest.java:42)”

Any help would be appreciated,thanks.

findElementsByAccessibilityId = many elements. Not one. If you need one use

findElementByAccessibilityId

@Aleksei could you help me resolving the following error:

Exception in thread “main” org.openqa.selenium.WebDriverException: Returned value cannot be converted to WebElement: {element-6066-11e4-a52e-4f735466cecf=8d3561ee-f057-4d5a-9023-c97d4ac5b78e, ELEMENT=8d3561ee-f057-4d5a-9023-c97d4ac5b78e}

Thanks

here is the code that I am trying:
try {
AppiumDriver driver = new AndroidDriver(new URL(“http://0.0.0.0:4723/wd/hub”), caps);
// MobileElement emailinput = (MobileElement) driver.findElementByAccessibilityId(“mailEntry”);
//MobileElement emailinput = driver.findElementByAccessibilityId(“BtnLogin”);
MobileElement emailinput = driver.findElementByXPath("//android.widget.Button[@content-desc=“BtnLogin”]");

		    	 //MobileElement emailinput = (MobileElement) driver.findElementByClassName("android.view.View");
		        emailinput.submit();
		        //emailinput.sendKeys("[email protected]");
			    driver.closeApp();
			
		} catch (MalformedURLException e) {
			System.out.println(e.getMessage());
		}

@Monti_Kabir

  1. what exactly line shows error?
  2. emailinput.submit(); - remove this. use either setValue() or tap element and then sendKeys() (sendKeys requires keyboard open)

@Aleksei this is the line thats causing the error.not sure why it’s showing this “Exception in thread “main” org.openqa.selenium.WebDriverException: Returned value cannot be converted to WebElement: {element-6066-11e4-a52e-4f735466cecf=8d3561ee-f057-4d5a-9023-c97d4ac5b78e, ELEMENT=8d3561ee-f057-4d5a-9023-c97d4ac5b78e}

I would really appreciate your response,thanks.

@Monti_Kabir try it like:

MobileElement emailinput = (MobileElement) driver.findElementByXPath("//android.widget.Button[@content-desc=“BtnLogin”]");``
