Re: [Inf-IT DAVcl] Sync, sync, sync


Hi Johan,

there are indeed issues like this in recent Android version. Most
notably Samsung and Huawei are very restrictive in this regard. For
instance, it seems that (some?) Samsung devices completely disable
background operations of an app which hasn't been opened once in three
days. For a background sync app that's a big issue, because it's not
meant to be opened every three days. I haven't noticed this on Android
One devices though.

On some devices you can put apps onto the "do not optimize" white list
(that's on Samsung devices, in the battery menu). We've received reports
that this solves the issue.

We've also developed a workaround which appears to fix this. I'll
publish a release once I've managed to fix the new account setup.

Cheers,

Marten
