Fix a small simple mobile app in .Net Xamarin

A simple app primarily that ;

* scans a QRcode

* sends that code and an inbuilt serial number to the server

* move to screen 2 and opens a web view to display a web page.

Second screen allows the user to go back to the first or close the app.

Second screen button (if user taps) will send a message to the server via an API.

When app is installed it will load a code stored in the app, into the app data safe are.

When the app scans the QR code it sends a Restful to the server with the QRcode and App code (serial number)

I have a wire frame design (attached) to shows the UI.

I have the app mostly completed but for some reason the QR reader is not scanning. Some other items might need attention also because I cannot test it until the QR works.


it must use ZBar not Zxing


This project Android Gradle from Github works very well. If the scanning and zoom part of that can be built as a library jar and then linked into the Xamarin (which I read is possible) that would work well I think.

Needed in about 2 days pls.
