Add Style to an already functional Android App

The core of this application is already functional from a previous project. This stage of the project is going to style the app and add a few functions. Requirements 1. Add QR code reading capability to the app. You can use a 3rd party scanner like [login to view URL] to read the QR codes similar to how Google Authenticator works. If you can do it natively that would be awesome. 2. Add a report issue option that will open an email for the individual using the app to send a message with the copy of the link in the subject line. 3. Allow users to move between the three different profiles of the link that is currently loaded. 4. Style the app to match the style mockups included in this document. Please see attached docs including current working prototype app and mockups. Areas in purple in the workflow app are the new functions. All graphic assets will be provided in high res.
