Is there a solution for the aosp contacts app address problem?

---

I’m syncing Lineage14 adress book by davdroid wiht nextcloud10.

Every time I edit any element of a contact on phone with the aosp contacts app, the sync of postal address for this contact doesn’t work anymore.

To repair it, I have to delete the postal address element. Then do a sync, which removes the address from nextcloud. After this I can add the address element again by nextclouds contacts app and sync it to the phone.

Because of this behavior the address sync of a lot of my contacts is broken. There is no easy way to recognise the problem, because there are no failure messages.

I think the problem is the postal address handling of the aosp contacts app.

Would it be possible to patch the aosp contacts app?

Or is there another contacts app, which I can use without gapps?

Here is our FAQ entry about it, since it is being asked often!

Of course someone can patch the AOSP contacts app - but it’s hard to find the individuals at Google who do it, I guess…

Thanks, I read your FAQ.

If I understand it right, there is no solution for the address breaking problem between android and nextcloud. Right?

There seem’s to be no other contacts app for android available except from googles play store.

Didn’t I read anywhere that you patched the AOSP contacts app for group functionality and the lineage team has integrated your patch?

I found a solution.

There is a free contacts editor app at googles playstore, which provides separate fields for street, city etc.
https://play.google.com/store/apps/details?id=org.dmfs.android.contacts
https://dmfs.org/editor/?getit

It integrates itself into the aosp contacts app only for editing of contacts.

I downloaded the apk from playstore with the webdownloader at evozi.com
