Android QR code scanner

Hello, I am looking for someone that can help me create a QR code scanner for android that I can integrate into my app. Most important: I do NOT want to depend on 3rd party app. Preferably with zxing framework, but I am open to suggestions. I would like to get an example application that contains a button. When the button is clicked the camera window opens to scan the qr code and returns the qr code that is scanned. Deliverable - Example application with single button that opens camera to scan QR code and textview that displays the scanned qr code. - Easy to copy for me into my own application (eclipse environment). - NOT depending on third party apps. - Code commented where needed
