Calendar is not syncing when remote calendar name contains a whitespace

  • I’m using Baikal as a CalDav server. I gave such name to my calendar:
    “Kalendarz CalDav”

    DavDroid didn’t sync the calendar. I’ve installed CatLog for debugging and found the message saying that there’s forbidden sign in calendar name. I changed the name to:
    and reconfigured DavDroid from scratch and it started working.

    My addressbook also had a whitespace in the name, but syncing was ok.

    Thanks for your report. Please read Reporting issues and provide all information mentioned there, including detailled steps to reproduce the issue and verbose logs.

  • SW releases:
    Device: ZTE Grand X In
    Android version: 4.0.4 (GXI_V1.0.0B02)
    DavDroid version: 0.6.2 from F-droid
    Server version: Baikal 0.2.7 on centos 6.4 (Virtual Server, Apache is using .well-known)

    Steps to reproduce:

    1. Go to Baikal Server -> Users and resources -> Calendars
    2. Edit calendar
    3. Change Display name so that it contains a whitespace e.g. My Calendar
    4. Save changes
    5. On android device, go to DavDroid and add an account for syncing

    Calendar is not syncing when a whitespace is in calendar’s name. Contacts are syncing with no problem though there’s also a whitespace in calendar’s display name.

    Expected behaviour:
    Calendar is syncing.

    Unfortunately I didn’t manage to collect the logs and I’m currently to busy to play around with that. In general when I opened CatLog and filtered with DavDroid I could see an error regarding calendar syncing similar to:
    Unexpected character at 3 column in “My Calendar”
    Forbidden character at 3 column in “My Calendar”

    Just a guess, but maybe the server sends a whitespace in the URL instead of %20?

  • Hmm, not sure. Note that it is not a calendar name but calendar display name.
    In my particular situation it was:
    Calendar name: default
    Calendar display name: Kalendarz CalDav

    So the URL is like:
    And when metadata is downloaded to DavCal after successful logging in I can see the calendar display name in DavCal.

    Can’t reproduce this problem: I have just tried with Baikal 0.2.7 and the current DAVdroid version and a calendar with Display Name “My Calendar With Whitespace” was added and synchronized without problems.

    Maybe your problem is not related to the Display Name? Can you provide logs or a demo account (
