AppiumFieldDecorator is not working with POM

Question

I am trying to automate with Appium, TestNG and Maven. I am getting errors while initializing the page object model. An error log is attached with this. Tried many ways, but no luck. It would be great if anyone know where I am doing mistakes. java-client --> 6.1.0 testng --> 7.4.0

public final class Driver {
    public static void initDriver() {
        if (Objects.isNull(DriverManager.getDriver())) {
            URL url = null;
            try {
                url = new URL("http://127.0.0.1:4723/wd/hub");
            } catch (MalformedURLException e) {
                e.printStackTrace();
            }
            DesiredCapabilities capability = new DesiredCapabilities();
            capability.setCapability(MobileCapabilityType.PLATFORM_NAME, MobilePlatform.ANDROID);
            capability.setCapability("appPackage", AppConstant.appPackage);
            capability.setCapability("appActivity", AppConstant.appActivity);
            
            AppiumDriver<MobileElement> driver = new AppiumDriver<>(url, capability);
            DriverManager.setDriver(driver);
        }
    }
}

public final class DriverManager {
    private static ThreadLocal<AppiumDriver<MobileElement>> driver = new ThreadLocal<AppiumDriver<MobileElement>>();
    
    public static AppiumDriver<MobileElement> getDriver() {
        return driver.get();
    }
    static void setDriver(AppiumDriver<MobileElement> driverRef) {
        driver.set(driverRef);
    }
}

public class HomePage{
    
    @AndroidFindBy(xpath="//*[@content-desc='Accessibility']")
    private MobileElement eleAccessibility;
    
    public HomePage(){
        PageFactory.initElements(new AppiumFieldDecorator(DriverManager.getDriver(), Duration.ofSeconds(10)), this);}
    
    public void clickAccessibility() {
        eleAccessibility.click();
    }
}

I am getting below error....

I was also facing this issue and I was able to resole using below steps

Remove the constructor HomePage()
Now in the class were you are calling your page object class there call it in below format.
```
HomePage hommePagePO = PageFactory.intiElement(driver, HomePage.class);
```

For example: PageObject class:

 public class HomePage{
    @AndroidFindBy(xpath="//*[@content-desc='Accessibility']")
    private MobileElement eleAccessibility;

    public void clickAccessibility() {
    eleAccessibility.click();
    }
    }

Test Class:

  @BeforeClass
   public void setup(){
   // initialize your driver and then pass the driver
   
   HomePage homePagePO = PageFactory.initElements(driver, HomePage.class);
   }

Or

When you are creating your pageObject call constructor, call the initElement like given below:

PageObject class:

 public class HomePage{

    public Home(Appium driver){
    PageFactory.intiElement(driver, this.getClass());
    }
    @AndroidFindBy(xpath="//*[@content-desc='Accessibility']")
    private MobileElement eleAccessibility;
    Page
    public void clickAccessibility() {
    eleAccessibility.click();
    }
    }

Thanks Suhail. I was exhausted looking into other solution. This worked for me. Previously above code worked. Not sure why it is changed like this. — Gopinath V S, Jan 12 '23 at 16:37
