Now that you have the basics of scanning the QR code down, it’s time to make this app into something genuinely useful.
Make use of SQLite to save the contacts. As soon as the user scans a qr code then the data should be added into the database.

For each contact, please display:
Please make sure that the user can scroll through the list. There might be a lot of contacts.

When the user is on the contact details screen, they should be able to navigate:
When the user is on the camera screen they should be able to “go back” to wherever they were before.
