I have a Ionic1 app that provides to the users the possibility to download files (zip, pdf, doc) from a server and store them locally in order to be available off-line.
I need help how to manage files update on the server (no backend API provided by the server-side).
Today a user download a pdf file from the app.
Tomorrow I will updated the same pdf file on the server and what I want is to implement a function that understand that the file needs to be re-downloaded (updated).
Any helps/idea will be much appreciated.
Thank you in advance.
