I cant get DAVx5 working on a Note 4 with Andorid 4.4.4.
I can set up accounts for caldav and carddav (using URL+login), but when I select the newly created account tab, the app closes/crashes.
I’ve purged cache, deleted the accounts and repeated setup with the same outcome.
This phone has a data only SIM =, but crashes occur whether I use data or wifi.
Just noticed that the app also crashes when I select “About /License”
Does this also happen with DAVx⁵ 22.214.171.124? Looks like a duplicate of https://forums.bitfire.at/topic/2110/android-4-4-davx-2-5-4-ui-fails-on-opening-an-existing-account/8
Couldn’t find that version on Google Play, but I located it on Fdroid… 126.96.36.199 seems to be good … carddav and caldav syncing with Synology DSM 6.2, Even the app’s “About / License” displays without crashing.
Thanks for sticking w/4.4 … My Nexus 5x died yesterday and I’m attempting to get back online with my data-only Note 4.
@Telos Unfortunately, Google Play hasn’t released the version yet. They say it can take “a few days”… Happy that it now works for you.
DAVx⁵ 188.8.131.52 is now available in Google Play, too.
