Sync not running automatically

---

Hi

Using davdroid, i saw a bug. Sometimes the schedule sync is not working, as shown on this first screen (see the dates)

To resolve, i just have to open davdroid app and validate the popup like here

When i do it, going back to account and the sync is done…
It seems the popup is making problems ?

Hello,

1. Please use the forum syntax properly, because the links are nearly unusable. There’s a help function (questing mark) on the right top of the edit field. You can also attach files directly, without using another hoster.
2. The open-source popup is in no way related to synchronization.
3. Android will show “synchronization problems” on soft errors, i.e. if your mobile connection is interrupted during a synchronization. The problem will disappear as soon as another synchronization is done correctly. This may have a random temporal correlation with clicking on popups.
4. Please provide steps to reproduce, debug info and verbose logs.

Hi
Sorry for delay.

To reproduce, nothing to do. Just have a working caldav/carddav account, and wait some days…
In accounts on android parameters I see the account is not refreshed since days. Forcing manually update do nothing. The only way to make it work again is start manually davdroid app, and it’s resolved, until next time.

Logs will probably show nothing because when I start the debug mode, the app was running so account refreshed…

Here are debug info :

Synchronization is managed by Android. DAVdroid doesn’t run all time, it’s just called by the synchronization framework of Android. So, if synchronization is not started, I guess there’s something wrong with Android settings. Maybe adb logcat would reveal more information.

Is your question answered by the recently created FAQ: Why is synchronisation not triggered as set it in sync interval settings?

It’s probably related to doze mode, but i use my phone very often and when it happens davdroid do not sync for days.

@ouafnico Is is possible the your system moves DAVdroid to App Standby?

Is it correct that if synchronization stops working:

• you can start DAVdroid and synchronize manually,
• and then automatic synchronization works for a few days days, before stopping again?

@ouafnico Does it help to turn off doze mode / app standby for DAVdroid? Android settings / Battery / Battery optimization / DAVdroid and then choose “Don’t optimize”.

It seems to correspond to the app standby.
I’ve added davdroid out of battery optimization. I will see…
