Just joined: first post!
I work for a company that creates digital signs using a variety of Android players and screens. Recently we received a demo screen that is using Android TV (Android 10).
We have a suite of apps that read and write to the same folder tree of files … each folder can contain xml, image files, mp4 files, etc. and which folder its in is important as well.
One of our apps monitors the content files in the background, comparing them to versions on the server and updating them as necessary while another app reads the files and displays them. Until Android 10 this has all worked swimmingly.
But, I haven’t found a method on Android 10 where my app can update files in the background without having to pop up some request to the user. Obviously, popping up a save dialog isn’t ideal on a digital sign… Or, at best I can create a file but I can’t then rename it, update it or delete it.
I’ve read through a quite a number of the commonware blog posts and browsed through the books and I haven’t seen any method where I can write/update/delete/rename files in the background that would be accessible to other apps.
Am I missing something? Is there a way to do this on Android 10?
