Implement Google Contact Sync

[isthisme]

This would be a nice feature to have since the contact sync .apk from Google is proprietary.

You should be able to sync contacts using the open-source CardDAV client DAVdroid (available on F-Droid). Use the following details to setup the account:

• "Login with URL and user name"
• Base URL: "https://www.googleapis.com/"
• User name: Full Google account name (including @googlemail.com/gmail.com)
• Password: Your Google account password

I am not sure if all features are implemented correctly in Google's CardDAV interface. It's the same API used for Apple clients, so it shouldn't be too bad ;)

This only seems to work with Google contacts - is there a way to sync Google calendar too?

[mar-v-in]

It should be possible to install and use the Google Calendar app

[JonnyTech]

I am using CM13 and it has a calendar app - looking at app details it is com.android.calendar version 6.0.1 - but DAVdroid has the issue connecting to the sync service, is there anything that I can check?

[mar-v-in]

There is a dedicated "Google Calendar" app in the Play Store, that's not the same app as the AOSP calendar (or derivates thereof)

[ale5000-git]

There is also a Calendar Sync apk that possibly work together the AOSP calendar but I'm not sure.

Thanks, I found a solution, use the following server url with DAVdroid:

https://www.google.com/calendar/dav/my.email.address@google.com/events

Replace my.email.address@google.com with your full GMail address.

It syncs both my contacts and calendar from that location.

Only my primary calendar is visible but that is all that I need.

If somebody needs to sync a non primary calendar, look in the google calendar web interface for the Calendar ID. Press the gear top right, select settings, select calendars, then select the calendar you want to sync. The Calendar ID should be something like d4jg8dj5ng8ek5jdhrn4udje8@group.calendar.google.com Then use https://www.google.com/calendar/dav/my.calendar.id@google.com/events as base URL in DAVdroid. Replace my.calendar.id@google.com with your calendar id.

can google contact and/or calendar sync client be used without granting it system permissions?

[Lanchon]

gmail sync is working. i installed GoogleContactsSyncAdapter.apk as a regular app (obtained from opengapps) and i haven't been able to make it work.

UPDATE: yes it works! i had enabled the contacts permission in the GoogleContactsSyncAdapter app, but nothing happened. after a while, CM's privacy guard popped up asking about contact access. i granted that and sync started.

i went to the account but only gmail sync showed. later contact sync appeared. (i installed google's contact app and fiddle with its settings in between, FYI.) everything seems to be working fine.

[Lanchon]

same dance, i installed GoogleCalendarSyncAdapter.apk, enabled the calendar permission, enabled calendar access on the privacy guard popup, and cal sync is working too!

supports multiple calendars.

I'm trying to get this working, but it keeps throwing "Couldn't find CalDAV or CardDAV service."

After some digging, it seems that Google is swatting me down with an authentication error. But why?

Thank you! But did not fix. :(

[JonnyTech]

Have you allowed "less secure" access? https://support.google.com/accounts/answer/6010255?hl=en

[coyoteltd]

Also did not fix. :(

[JonnyTech]

Are you using the URLs from https://github.com/microg/android_packages_apps_GmsCore/issues/222#issuecomment-261253801

Can you view your contacts at http://contacts.google.com/

[coyoteltd]

Yes, I can view my contacts just fine. I've tried with every URL in this thread and one I found by Googling.

I've checked my password 20 times (it's definitely right) and tried with myemail, myemail@gmail.com, myemail@googlemail.com. . .

The logs just say "Invalid Credentials" every time.

[JonnyTech]

Is there a special character in your password? Try setting it to something simple. Ref: https://davdroid.bitfire.at/faq/entry/password-not-accepted/

[anunaym14]

I refereed to the second post here to setup DAVDroid with microg but the error I get is CalDAV/CardDAV service not found! Please help ASAP!

[JonnyTech]

Keep reading... see my reply above: https://github.com/microg/android_packages_apps_GmsCore/issues/222#issuecomment-261253801

[anunaym14]

Tried it! Same error! I have to replace it with my email right? I tried by replacing to anunaym14@gmail.com and got the same error!

[anunaym14]

If u want I can send you logs via telegram. Ping me @anunaym14

[JonnyTech]

In DAVdroid: Add account >> Select "Login with URL and user name"

Base URL = https://www.google.com/calendar/dav/anunaym14@gmail.com@google.com/events User name = anunaym14@gmail.com Password = \<your-password>

I just checked it with my account and it works.

Did you allow "less secure apps" on your google account? https://github.com/microg/android_packages_apps_GmsCore/issues/222#issuecomment-269888617

[anunaym14]

How to allow "less secure apps" on google account? I tried again, didn't work!

[JonnyTech]

It is best to do it on a computer:

• open a web browser
• log into your Google email
• go to https://www.google.com/settings/security/lesssecureapps
• turn on "Allow less secure apps"

Now you can use non Google products, such as DAVdroid to access your account

Also try this: https://accounts.google.com/b/0/displayunlockcaptcha

[JonnyTech]

I do not understand your question. If it is not related to this issue then please open another.

EDIT: I see that you deleted your last post...

[anunaym14]

Thank you so much for this blazing fast support!

Edit : Yes, I deleted it because its solved!

[matttbe]

Hello,

Thank you for the tip but note that it seems the previous URL is deprecated. I was able to use something like for my "business" account:

https://calendar.google.com/calendar/dav/<full@email.tld>/events

But we should use one of these two URLs:

https://apidata.googleusercontent.com/caldav/v2/<CAL_ID>/user
https://apidata.googleusercontent.com/caldav/v2/<CAL_ID>/events

More info: https://developers.google.com/google-apps/calendar/caldav/v2/guide

https://github.com/microg/android_packages_apps_GmsCore/issues/222#issuecomment-268444784 is worth adding to FAQ. Properly rephrased, of course.
