"Retrieving Calendar Data"

[sjamie]

Unfortunately, the calendar has always been slow for me. I sync less than 700 events every 90 days most of which are recurring.

Any suggestions?

This problem started for me in the middle of last week. Before that, I had no problem. Now, almost every time I turn the phone's screen on, "Retrieving calendar data" occurs, often twice in a row, the first to retrieve the current day's appointments and the second to retrieve the adjoining days' appointments. This is true even though I haven't gone out of Calendar into any other phone function from before the screen went to sleep until I looked at it again.

I have a Samsung Galaxy S3 running Android 4.1.2.

Perhaps it is a coincidence, but ...

The problem is no longer occurring. The only change I made to my phone was turning GPS off.

Mel, Probably not a GPS issue.

What is happening is that it is generating a list of "virtual appointments" based on a recurring pattern. However, once created, DejaOffice doesn't do it again, unless the virtual table is lost. The virtual table is lost on a reboot.

Sometimes a particular recurring can cause a lot of regeneration. This is something like a daily recurring appointment "Lunch" or "Go Home" for instance. If it is in a big pattern (repeat every day forever) then it will cause a lot of regeneration.

Glad to hear it went away. The system is supposed to be "self healing" but unfortunately it's not magical.

What's the best way to deal with daily recurring appointments (ie. "Go to Gym", "Pick up Kids", etc.) to minimize regeneration and performance lag? I have many appointments of this type.

[DJOCTO]

So do I!

If lag is a problem, just cut off the current one, and start a new one tomorrow. As soon as the old one is no longer in the display range, it no longer is part of the regeneration.

If you already have a lot of changes this month, just put an end date of December 1, and start a new one December 2.

A good balance is no more than 30 changes (instances) for a single appointment. So if you change every day, start a new one every month. I change 1-2 a month, and have been doing it for years so I have about 60 instances attached to some of my daily events. For me it is exercise, and certain meetings I go to nearly every day.

Thanks for the suggestion; however, I can't see me redoing my recurring appointments every month. Other calendars I've tried have no problem with having numerous recurring appointments and they open instantly. Unfortunately, they don't sync well with Outlook...

This seems to be improved with the new 3.1.2 release.
Even with a lot of recurring appts, its now loading faster, due to the log file that was uploaded in that other thread.

So whatever they did, it worked.
Maybe they can improve it even more? It now seems to load the Calendar in about 5 secs, without all the choking on the recurring appts.

Some people use lots of recurring appts for productivity management, things like daily Exercise, etc.
So you can easily have 10-20 recurring appts daily.

So whatever they did, maybe they can continue to improve it, and make it even faster?

I also have problems with "Retrieving calendar data" it just goes on and on as soon as I start calendar and today Dejaoffice has crashed twice and I have sent the crash logg. My Sony Xperia Z5 was recently updated to 32.3.A.2.33 and it runs Android 7.0. My older Sony pad that runs Android 6.0.1 hasn't any problems. I sync via DejaCloud. And it's Outlook 2016 that's syncing.
