No sync with iCloud on Android phone

[bbnetworks]

After installation & configuration of CalDav on my android phone, all my iCloud calendar items are loaded onto the android phone, but after that no new calendar items are loaded, even when manually syncing. Android phone: Sony Xperia-Z

There have been otter issues (e.g. #168, #151) reporting this, but I'll report my findings here.

From what I've observed, it aopears that iCloud servers have an additional second element in responses to requests retrieving calandar lists. These elements have empty string values for and and are accompanied by an error status (404 Not Found). The current implementation (1.8.1) overwrites the valid values in the first propstat element by these empty values in the second. The net effect is that the ctag is always empty so it appears that the calendar never changes.

I've implemented a change in a local copy of CalandarsHandler to ignore any values in propstat elements that have an error status code. This fixes the ctag issue but I still found it necessary to add an automatic timed sync to get updates from the server with any regularity. (I used a 30 minute sync period.)

Happy to share any of this with anybody doing active development on AndroidCaldavSyncAdapater.

Hello,

Thanks for the update. Can you share a modified version with me, so I can try it?

Best regards, Dirk

Hello Dirk,

Not sure exactly what you're looking for. E.g., I could email you the modified source for the CalendarsHandler class that you could use to build and test your own version. If you're looking for a packaged app, that would take a bit more time. In either case, I'd need your email address.
