如何在java中从输入流中读取png图像

Question

There are 2 applications. One application act as server and sends continuously screen shot of desktop by using the following code.

Robot robot=new Robot();
OutputStream os;
BufferedImage image = robot.createScreenCapture(new Rectangle(Toolkit.getDefaultToolkit().getScreenSize()));
ImageIO.write(image, "png", os);

The second application is Android application acts a client application and has to read continuously the above image stream from inputstream.

Could please help me to read the png images from inputstream in the client application.

Thanks & Regards Mini.

Answer 1

In client application, read the InputStream via Socket.getInputStream() method.

 BufferedInputStream in = new BufferedInputStream(socket.getInputStream());
 BufferedImage image = ImageIO.read(in);

Answer 2

Android SDK does not support the method ImageIO.read(). Even if you can compile your code, your android application will get crashed and have error about missing libraries like this:

could not find method javax.imageio.imageio.read

What I suggest is using bitmapping instead of this...
