The magic happens in QRCodeServlet.java. Here we uses QRGen library along with ZXing and generates QR Code for given text (Text we get from request.getParameter). Once the QR Stream is generated, we write this to response and set appropriate content type.

I search all over the place to integrate this code with android. so far the only problem is with the class awt (java.awt.* ) Its not available for android. Is there any method by with I can integrate the code over to android,
