I'm trying to create an app whereby a user will have a calendar tailored to them containing all their important dates. There needs to be a way for a non tech-savvy person to update a users calendar and push the updates to a users phone.
I am aware android has a built-in calendar but I'm unsure how updates will be pushed to a users calendar. I'm hoping that a calendar can be stored as a single file on a database and when a user refreshes their calendar it simply replaces their current calendar file with a newer calendar file.
Any and all advice would be highly appreciated.
