J2ME QR Code Application

We need to develop a simple QR Code decoder application which works on Nokia Series S40 devices. The Application must start with the camera enabled and should try scanning the QR Code until it finds one or the user presses the exit button. Once the application finds the QR Code it should send it to our server for validation. The validation procedure is simple and will be done by the server and return either true or false only (not in scope of this application). Important Points: The code inside the QR Code will be of 32 characters always. The device must show an error if the phone does not have a camera, or it unsupported. The application must not crash, and error reports should be sent via email to the administrator
