Как работает Get Active Element

В appium документации есть Get Active Element.

Так же есть пример:

WebElement currentElement = driver.switchTo().activeElement();

Я использовал его в своем примере:

public class Run_test extends Base_metod {
public static void main(String[] args) {
        Base_metod.appium_option_asus();
        wait_element("mobi.sevenwinds.askedo:id/iv_logo");
        wait_element("mobi.sevenwinds.askedo:id/tv_city");
        WebElement currentElement = driver.switchTo().activeElement();
}

Компилятор выдает ошибку:
