Error returned value cannot be converted into web element

[nava790]

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]

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

Can you please instruct me how to do that?

[Shubham_Agarwal]

cannot be converted to WebElement:

try this one-

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

[Qualay]

@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”);
