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..
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
working and library can be found here.. http://www.java2s.com/Code/Jar/d/Downloadddmlibjar.htm
Take Screenshot :
ProcessBuilder processBuilderq1 = new ProcessBuilder(new String[] { "cmd.exe", "/c", "adb shell /system/bin/screencap -p /sdcard/s.png"});
Process pq1 = processBuilderq1.start();
Pull to PC :
ProcessBuilder processBuilderq1 = new ProcessBuilder(new String[] { "cmd.exe", "/c", "adb pull /sdcard/s.png D:\\Images\\s1.png"});
Process pq1 = processBuilderq1.start();
you might want to check this. How to programmatically take a screenshot in Android?
Try taking the picture and saving it in a separate process.
you can try calling ADB in your program (supposing USB driver are installed and computer authorized on the mobile):
Using perl:

You can call executable in Java using: Process process = new ProcessBuilder("C:\\\\PathToExe\\\\MyExe.exe","param1","param2").start();
Source: Java Programming: call an exe from Java and passing parameters
