Getting Method is not implemented error for using new Ashot() on Android

I am using below keyword to take element screenshot of my Android mobile application.
After referring various topics from Katalon Community still unable to find any solution on this and getting below error.
Using Katalon Version 6.4 and Appium 1.8.1

rg.openqa.selenium.WebDriverException: Method is not implemented (WARNING: The server did not provide any stacktrace information)

My Keyword :
def takeElementScreenshot(TestObject objectWithXpath)
AppiumDriver<?> driver = MobileDriverFactory.getDriver()
Screenshot screenshot = new AShot().shootingStrategy(ShootingStrategies.scaling(1)).takeScreenshot(driver, driver.findElements(By.xpath(objectWithXpath.findPropertyValue(“xpath”))))
ImageIO.write(screenshot.getImage(), “jpg”, new File(System.getProperty(“usr.dir”)+“/image/ElementScreenshot.jpg”))

Can anyone please help me to resolve this issue ?
