Element not found exception using id or xpath attribute with @AndroidFindBy

Description

I am writing a simple login test for my Android app using the Appium-java client.
I am also using Page Object Model and Page Factory class to initialize elements in my test.
The test is failing as it cannot locate the email address input field.
I tried to locate the email field using both id and xpath attribute with @AndroidFindBy field decorator but it [didn't] work.
Looking for help on this issue.

Environment

• Java client build version: 8.5.1
• Appium server version or git revision if you use some snapshot: Appium v2.0.0-rc.5
• Device: Android emulator

Code To Reproduce Issue [ Good To Have ]

BasePage.java:

public class BasePage {
    AppiumDriver driver;
    public static final long WAIT = 30;

    public BasePage(AppiumDriver appiumDriver) {
        PageFactory.initElements(new AppiumFieldDecorator(appiumDriver), this);
        driver = appiumDriver;
    }

    public void click(WebElement element) {
        waitForVisibility(element);
        element.click();
    }

    public void enterText(WebElement element, String text) throws InterruptedException {
        Thread.sleep(20000);
        element.sendKeys(text);
    }
}

LoginPage.java

public class LoginPage extends BasePage {
    public LoginPage(AppiumDriver appiumDriver) {

        super(appiumDriver);
    }

    @AndroidFindBy(id = "loginId")
    WebElement emailAddressInput;

    @AndroidFindBy(id = "button-username")
    @iOSXCUITFindBy(id = "button-username")
    WebElement continueButton;

    @FindBy(id = "password")
    @iOSXCUITFindBy(id = "password")
    WebElement passwordInput;

    @AndroidFindBy(id = "button-password")
    @iOSXCUITFindBy(id = "button-password")
    WebElement signInButton;

    public void enterEmailAddressAndProceed(String email) throws InterruptedException {
        enterText(emailAddressInput, email);
        enterText(passwordInput, "password");
        //click(continueButton);
    }
}

BaseTest.java

public class BaseTest {

    public static AppiumDriver driver;
    public static void androidSetUp() throws MalformedURLException {
        DesiredCapabilities capabilities = new DesiredCapabilities();
        capabilities.setCapability("platformName", "Android");
        capabilities.setCapability("appium:automationName", "UiAutomator2");
        capabilities.setCapability("appium:platformVersion", "14");
        capabilities.setCapability("appium:deviceName", "Android Emulator");
        capabilities.setCapability("adbExecTimeout", 900000);
        capabilities.setCapability("uiautomator2ServerLaunchTimeout", 50000);
        capabilities.setCapability("appium:appWaitActivity", "com.vimcar.nextlogbook.feature.useronboarding.authentication.presentation.LoginActivity");
        capabilities.setCapability("appium:newCommandTimeout", 120);
        capabilities.setCapability("appium:app", System.getProperty("user.dir")+"/src/test/resources/next-logbook-debug.apk");

        driver = new AndroidDriver(new URL("http://localhost:4723/wd/hub"), capabilities);
    }

    public static void tearDown() {
        if(null != driver) {
            driver.quit();
        }
    }
}

LoginTest.java

public class LoginTest extends BaseTest {
    LoginPage loginPage;

    @Test
    public void existingUserLoginTest() throws Exception {
        androidSetUp();
        loginPage = new LoginPage(driver);
        loginPage.enterEmailAddressAndProceed("prateek.saxena+demo@avrios.com");
        tearDown();
    }
}

Appium inspector screenshot:

Start by reviewing the locator declarations and initialization flow in BasePage.java and LoginPage.java, then compare the Android and XPath Appium logs with the inspector screenshot. Verify whether the failure is in the Java client lookup path or in the app's reported element attributes; done means identifying a reproducible cause and documenting the required correction.
