I need to create an android application which pretty much works like a qr code decoder.

I want to use the android phone camera and read only the qr code from the camera preview, and send it to a decoder library probably zxing which gives me the result. I don’t want to use the zxing intent which uses another application barcode scanner.

I am able to take a picture using phone camera, but I don’t know how to read only the qr code part from the preview. I need help in this regard and also how to send the data to decoding library.

    That’s a pretty tall order to ask for here on SO. My advice would be to study the xzing source at http://code.google.com/p/zxing/ and/or see if you can legitimately incorporate it via the Apache 2.0 license into your project.
