Find element in bottom of screen

#1

Hello.
I am just start work with appium, and i have some problem
( starting android automation tests)
With annotation @FindBy(id = “someId”) works correctly only for element displayed on the screen.
I tried to fix it with

JavascriptExecutor js = (JavascriptExecutor) driver;
HashMap scrollObjects = new HashMap();
scrollObjects.put(“direction”, “down”);
scrollObjects.put(“element”,
((RemoteWebElement) someId).getId());
js.executeScript(“mobile: scrollTo”, scrollObjects);
Error:
java.lang.ClassCastException: com.sun.proxy.$Proxy11 cannot be cast to
org.openqa.selenium.remote.RemoteWebElement

Tried something like that

touchAction.moveTo(someId);
Error:
java.lang.NullPointerException

Can someone help?

I initializad elements with PageFactory.initElements(driver, this);

#2

->

((MobileElement) your_element).getId());

#3

With ((MobileElement) your_element).getId()) i have next error

java.lang.IllegalArgumentException: Can not set io.appium.java_client.MobileElement field elements.FilterElements.MyElement to com.sun.proxy.$Proxy11

Same thing.

@FindBy(id = “element”)
private WebElement MyElement;

Constructor

public FilterElements(AndroidDriver driver) {
this.driver = driver;
PageFactory.initElements(driver, this);
basePage = new BasePage(driver);
}

If i try do

@AndroidFindBy(id = “element”)
private MobileElement MyElement;
Error:
java.lang.IllegalArgumentException: Can not set io.appium.java_client.MobileElement field elements.FilterElements.element to com.sun.proxy.$Proxy11

update page to:

    public Page(WebDriver driver) {
        this.driver = driver;
        PageFactory.initElements(new AppiumFieldDecorator(driver, default_time_in_sec, TimeUnit.SECONDS), this);
    }
Getting java.lang.RuntimeException: java.lang.NoSuchMethodException: jdk.proxy2.$Proxy5.proxyClassLookup() while executing the tests through mvn command
#5

public FilterElements(WebDriver driver) {
this.driver = driver;
PageFactory.initElements(new AppiumFieldDecorator(driver, 100, TimeUnit.SECONDS), this);
}

But:

java.lang.NoSuchMethodError: com.google.common.base.Preconditions.checkArgument(ZLjava/lang/String;J)V

at io.appium.java_client.pagefactory.TimeOutDuration.setTime(TimeOutDuration.java:54)
