Option to work in background (with popup notification if someone tries to share a file)

[privsecti]

Describe the feature

Could you add option for the app to work in background?

I've been using it to send files between work profile and main profile, but since v1.9.1 if the app is not in foreground it disconnects from server so switching back and forth between apps does not work anymore.

Describe alternatives you've considered

Using older versions of the app or using from browser will work.

Additional context

Yes, the problem is that android activities aren't designed to run in the background.

One solution might be to create a ViewModel/LiveData backed implementation and start a background service with the same webview instance as soon as the activity is paused. Not sure if this will really work though...

Better would be a Foreground Service with a running notification*
On the other hand i'm not really sure its worth it, you can just open the app like once and start sending files, which you would have to do anyway for accepting files.

If you actually do want to pursue this heres a start
1.) create foreground service with notification

2.) include webview

3.) proabably best would be just to run the network.js and connect.js you can be inspired by my firefox addon which is basiclly doing the same (running a stripped down version for the background mode - checkout background.js)

if a file is send the app probably should be opened, but consider restrictions on starting activities
