Java - Get a screenshot of connected android device

I'm trying to write a java program that captures the current screen of the connected (via USB) android device and save it in the pc. I'm looking for any library I can use or any tutorial I can follow.. I'm really lost here..

Solution

  • get the device list from ADB

    IDevice[] devices = bridge.getDevices();

    Then you can get the specific device with serial number 

    d.getSerialNumber()

    Then capture the screen,

    RawImage rawImage = device.getScreenshot();

    convert raw data to an Image

        BufferedImage image = new BufferedImage(rawImage.width, rawImage.height,
            BufferedImage.TYPE_INT_ARGB);

    int index = 0;
    int IndexInc = rawImage.bpp >> 3;
    for (int y = 0 ; y < rawImage.height ; y++) {
        for (int x = 0 ; x < rawImage.width ; x++) {
            int value = rawImage.getARGB(index);
            index += IndexInc;
            image.setRGB(x, y, value);

    finally save the image

    ImageIO.write(image, "png", new File(filepath));

    use ddmlib.jar
