WebElement element = driver.findElement(MobileBy.AccessibilityId("login-button"));

// Using Android UiSelector
WebElement androidElement = driver.findElement(MobileBy.AndroidUIAutomator(
    "new UiSelector().resourceId(\"com.app:id/login\")"
));

// Using iOS Predicate String
WebElement iosElement = driver.findElement(MobileBy.iOSNsPredicateString(
    "name == 'login-button'"
));

Handling Mobile-Specific Gestures

Q: How do I implement touch gestures and mobile interactions?

Mobile applications require various gesture interactions that Appium supports through TouchAction and MultiTouchAction classes:
