So, ical4android expects uid2445 on API level 17+, but in your case, you have Android 4.2.2, but the column isn’t there. You can try to reset your calendar storage (Settings / Apps / Calendar Storage / Delete data) and add the DAVdroid account again. If it still doesn’t work, I’d suggest to use another firmware which behaves as documented (either a firmware update from your manufacturer, if available, or a custom ROM like CyanogenMod).
"E/A-Error: Cannot verify hostname" Owncloud + Android 5.0
The error message after pressing the “forward”-Button:
“E/A-Error: Cannot verify hostname: liberty42.de”
- Own Root Server
- Debian Wheezy
- OwnCloud 7.0
- StartSSL Certificate with RSA4096 and SHA-512 for liberty42.de
- Nexus 5
- Android 5.0
I considered to switch from CalDAV-Sync and CardDAV-Sync because your app is available via F-Droid and is FLOSS. Two very important arguments to prefer DAVdroid However, I had to switch back to CalDAV-Sync and CardDAV-Sync because DAVdroid is not working for me
Please install the certificate as described in the StartSSL manual - the intermediate certificate is missing and the chain thus invalid.
Congratulations to fixing it
