I have a web app that is running on an android tablet that is acting as a kios that allows a sales person to record daily activities on their routes. The Web app requires an Internet connection to transfer the data to a server database. However, there are instances that the Internet connection is unstable causing data loss in mid transfer. This is a problem for us.
I would like to know if it is possible to save the data locally into an ini file 5hat could be uploaded at a later time when a stable connection is available. I am thinking about using JavaScript, but not sure if this is the best solution.
The application is written in .NET Core and works great to save to a SQL server when Internet service is available.
Since the tablets are running Android OS, I am not sure if C# would work to save locally. But any solution will be satisfactory to save the data to an INI that I can retrieve at a later time to permanently save to the SQL Server.
