Update mobile database program

I need to update our current database program to the most recent version of Android OS.

It was developed using Xamarin.

After consulting with Xamarin expert this program was made in javascript as a website and cannot be updated. It must be made into a new mobile site. The features of this site include the following:
-connectivity to a cloud server database
-syncing information from the mobile device to the cloud server
-collecting information and storing it in a native database on the mobile device until synced with the cloud server
Attached is an outline of the necessary pages and functions of the mobile site.

Kemahiran: Android, Mobile App Development, MySQL, PHP, Xamarin
