local lan sync fails when there's no Internet connection

[nutpantz]

Problem scope

• I'm sure that this is a DAVx⁵ problem.

App version

• I'm using the latest available DAVx⁵ version.

Android version and device/firmware type

Android 12

Steps to reproduce

Create account on local network no internet server
Connect to server locally
Look at warning that no internet connectivity valadated
Fail to sync
It does nothing because Android thinks there is no internet.

Actual result

Create account on local network no internet server
Connect to server locally
Look at warning that no internet connectivity valadated
(It's a local server internet is not required)
It should sync since it can connect to the local server just fine

Expected result

Don't use Androids captive portal system to check if there is internet. Maybe ping the needed server. Which will work fine on s local network or one that uses the internet

Or just have a bypass option so that the app ignores Android questioning if there is internet. A network is still useful without internet.

[rfc2822]

It's a very complicated topic for very little users. However we still want to support this feature.

At the moment, syncing while Android says there's no connection is not in the scope of DAVx5. Make sure there's a validated Internet connection to synchronize. (Btw this is not the "captive portal system", but the NetworkManager API, which returns which connections are available and usable.)

I'll copy the issue over and mark this one as duplicate.
