Embed QR Code Scanner in Web View App

Please include the word 'hot dog' in your proposal. I need to embed a QR Code Scanning tool into an existing Android application that currently is based on webview. Workflow: User Pulls up App (Requests [login to view URL]) User clicks on link on website to do QR Scan (Requests [login to view URL]) Android App Provides QR Code Scanner Android App Redirects to and requests ([login to view URL]?qrdata=exampledatafromscan) Then scan is put into separate variables. You will have to have a knowledge of webview and PHP, and preferably this needs to be done today. It's not a hard project, I just can't wrap my mind around it.
