Screenshot using Robot.createScreenCapture returning black image?

Question

I'm trying to capture the screen using the below code on Windows 7

 Rectangle screenRect = new Rectangle(Toolkit.getDefaultToolkit().getScreenSize());
 BufferedImage capture = new Robot().createScreenCapture(screenRect);
 ImageIO.write(capture, "jpg", new File("C:/capture/ScreenShot.jpg"));

and this code is returning a black image, don't know why please help.

Imports are as below:

import java.awt.AWTException;
import java.awt.Dimension;
import java.awt.Rectangle;
import java.awt.Robot;
import java.awt.Toolkit;
import java.awt.image.BufferedImage;
import java.io.File;

Thank you in advance.

No issue in code...must be problem in package import... be insure you are import package java.awt.* or anything else??? — Saurabh Gaur, Jun 01 '16 at 11:00

@KishanPatel i can use something else but i'm worried because it's working for most of the people. Let me know if there is another good way of taking screenshots. — Nomi Khurram, Jun 01 '16 at 11:41

@SaurabhGaur i want to use that robot thing because i don't want to provide the url to web driver i want to capture whatever is open in the browser. — Nomi Khurram, Jun 01 '16 at 14:26

Check this, I think it will help you.

    public void screenCapture() {
    Dimension dimension = Toolkit.getDefaultToolkit().getScreenSize();
    Rectangle rectangle = new Rectangle(dimension);
    BufferedImage screen = robot.createScreenCapture(rectangle);
    try {
        ImageIO.write(screen, "jpg", new File("screenshot.jpg"));
    } catch (IOException e) {

        e.printStackTrace();
    }

And after just use this void. :)

Had a similar issue on Ubuntu with Java 11 and Java 12, fixed by upgrading to Java 13.

In my case, the problem was in wildfly startup mode. When it started as a service, I got a black screen. When I started it manually through standalone.bat the problem went away.

Maybe, there is another ScreenDevice.
Try

Robot r = new Robot(GraphicsEnvironment.getLocalGraphicsEnvironment().getDefaultScreenDevice());
BufferedImage capture = r.createScreenCapture(screenRect);
