@Tiberius1976 It seems that you’re affected by the problems with the version from Amazon, too. Others have this problem as well. Have a look here: https://forums.bitfire.at/topic/766/amazon-store-ical4j-exception-when-syncing-calendars
First Sync error
I’m trying to use davdroid for using a carddav server in a android. We use high-res photo on our server (we need that), but the transaction buffer is only 1 MB, and it throws the famous LocalStorageException. We use the last binary versions 0.8.0 . There is a workaround for importing without photos, or just some contacts at a time (and not the whole).
Same as #291. Unfortunately there is no such workaround…
Thanks for your report, but this is a duplicate of #230. Please follow up there.
