Xamarin Android

Wow that's a lot of work to do for a single thread :D

 

I would suggest you to look at the official Xamarin website and start learning the concepts and fundamentals of Xamarin.Android :https://developer.xamarin.com/guides/android/

 

Once you get the grasp of how it works then I'm sure you should be able to implement the application features you require. If you are having a hard time understanding ion connecting the dots then try to refer some tutorials and see if you can figure something out.

 

For example this one demonstrates how to create a Login system: https://www.youtube.com/watch?v=tf2O_t-ayJ8

 

And this one for multiscreen: https://developer.xamarin.com/guides/android/getting_started/hello,android_multiscreen/
