Error returned value cannot be converted into web element

nava790 · January 29, 2018, 7:59am

I am getting the below error

“Exception in thread “main” org.openqa.selenium.WebDriverException: Returned value cannot be converted to WebElement: {ELEMENT=1}”

This is my code

package androppium;

import java.net.MalformedURLException;
import java.util.concurrent.TimeUnit;

import io.appium.java_client.android.AndroidDriver;
import io.appium.java_client.android.AndroidElement;

public class basic extends base {

public static void main(String[] args) throws MalformedURLException {
	// TODO Auto-generated method stub

	AndroidDriver<AndroidElement> driver=Capabilities();
	driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
    
	
	driver.findElementByXPath("//android.widget.TextView[@text='Animation']").click();

eclipse console omitted the below error

have you tried with MobileElement instead of WebElement ?

nava790 · January 29, 2018, 9:17am

Thanks for the response@ Shubham_Agarwal
I Think i haven’t tried MobileElement.

Can you please instruct me how to do that?

Shubham_Agarwal · January 29, 2018, 9:31am

try this one-

MobileElement ele = driver.findElement(By.xpath(“//android.widget.TextView[@text=‘Animation’]”));
ele.click();

@Shubham_Agarwal…is there a known issue using Driver.findElement(By.id("…") ? Because I get the very same error as @nava790 testing out Appium with the emulator calculator. The Appium Inspector says it’s valid but executing any test fails with the line below. Is only XPath supported for Android? And it doesn’t matter if you use MobileElement or WebElement because it’s the “findElement(By.id())” logic that’s throwing the ClassCastException.

MobileElement el = _driver.findElement(By.id(“com.android.calculator2:id/digit_4”)).click();

I’m using the latest libs:

selenium-java-3.0.1.zip
java-client-6.0.0-BETA2.jar
client-combined-3.0.1-nodeps.jar
Server 1.7.2
Desktop 1.3.1
caps.setCapability(“appPackage”, “com.android.calculator2”);
caps.setCapability(“appActivity”, “com.android.calculator2.Calculator”);

I get the error:

Thanks @Shubham_Agarwal for the response
The mobile element didn’t worked for me

The Webelement got worked once i updated appium server to 1.7.2 and JDK to 8u161

Try the below combination @Qualay

selenium-java-3.7.1 jars
java-client-5.0.4.jar
appium Server 1.7.2
Jdk 8u161
