Show a warning in the main screen if Calendar or Contacts storage is deactivated/missing.

On some (mostly) Lineages it occurs that people deactivate these storages and then wonder why DAVx5 can't sync anything. There is no error message. We could for example show a error message in the main view like we do when there is no internet connection or bring a notification additionally. What do you think on this?

I think that's a nice idea 👍

Do you have a preference for a used card icon and description? I think both the questionmark (indicating something is missing) and the gears (indicating it's about the android internal system) are good. I lean towards the gears though.

Should there be a link to the manual ("Learn more") with explanation of how DAVx5 uses system apps? I would not show the package names com.android.providers.calendar and com.android.providers.contacts in the description then, but explain it in the manual instead.

I'd go for:

or

What do you think :) ?

Those are good too.

Or how about the android icon?

Also, what about the Link to the manual?

Mhm... I think the Android logo is too unspecific. The database symbol would indicate what really is the case: a db storage that is not present or not working. The "Alert" would indicate a status that is problematic and more severe I guess, while the database off would just show how the current state is without telling if severe or not. Theoretically it's fine for users to deactivate a certain storage if they don't need it. So maybe the "db off" icon fits a bit better. Otherwise for a good functionality of DAVx5 it's a important thing to keep these storages active.

A link to the introduction in the manual would be very good I think :) for example → https://manual.davx5.com/introduction.html#
