Android: Enhance error message when failing to sync file due to illegal filename

[hnicke]

I accidentally had a directory in my nextcloud which contained a colon in its filename, e.g. tro:lol. Btw, this is totally legal in unix and I think in OSX, aswell.

When trying to sync the folder (to the fat32 sdcard) with the android client, i get an error message.

Actual behaviour

• A notification is sent:

Download failed
Could not download tro:lol

In case a directory contains a colon, the dir including it's content does not sync.
In case a file contains the colon, the file is not synced.

Expected behaviour

• As far as I know the sync to external SD card can't work because on fat32, : is a reserved char. The error message should be more specific, e.g.:

Download failed
Could not download tro:lol : Illegal filename

Steps to reproduce

1. Create files on workstation in synced nextcloud folder: mkdir tro:lol; cd tro:lol; touch 1 2 3
2. wait till on server
3. in Android app, select the three dots of the tro:lol entry and select Sync.

Correct, we can enhance the error message, but the underlying error we cannot change…
