有没有办法在appium中截取全屏截图

import io.appium.java_client.AppiumDriver;
import io.appium.java_client.android.AndroidDriver;
import io.appium.java_client.android.AndroidElement;
import org.openqa.selenium.OutputType;
import org.openqa.selenium.TakesScreenshot;
import org.openqa.selenium.remote.DesiredCapabilities;

import java.io.File;
import java.io.IOException;

public class AppiumScreenshotExample {
    public static void main(String[] args) throws IOException {
        // 设置DesiredCapabilities
        DesiredCapabilities caps = new DesiredCapabilities();
        caps.setCapability("deviceName", "Android Emulator");
        caps.setCapability("platformName", "Android");
        caps.setCapability("appPackage", "com.example.app");
        caps.setCapability("appActivity", "com.example.app.MainActivity");

        // 初始化AppiumDriver
        AppiumDriver<AndroidElement> driver = new AndroidDriver<>(new URL("http://127.0.0.1:4723/wd/hub"), caps);

        // 截取全屏截图
        File screenshotFile = ((TakesScreenshot) driver).getScreenshotAs(OutputType.FILE);

        // 保存截图文件
        FileUtils.copyFile(screenshotFile, new File("path/to/save/screenshot.png"));

        // 关闭AppiumDriver
        driver.quit();
    }
}
