Can't seem to add existing contact to existing contact group

[KvB]

Hi all,

I'm trying to make my way through the google contacts api in java and
I want to be able to add or delete contacts from contact groups. So
far I haven't been succesful and I now have the following error.

When I run this code:

private void archiveContact(ContactEntry contact) throws Exception {
if (ARCHIVE_GROUP_ID == null) {
getArchiveGroupId();
}

GroupMembershipInfo gmsi = new GroupMembershipInfo();
gmsi.setHref(ARCHIVE_GROUP_ID);
contact.addGroupMembershipInfo(gmsi);

URL editUrl = new URL(contact.getEditLink().getHref());
myService.update(editUrl, contact);

}

I get this error:
com.google.gdata.util.InvalidEntryException: Bad Request
Group membership information not supported.

Does anyone have a working example of java usage of the api to add/
remove existing contacts to/from existing contact groups? Or can
anyone help me solve the error above?

Regards and thanks for any help in advance!

Hi,

I think the problem you are getting is because you need to use/get the
FULL protection for the Contact Entry, here is a small sample that
adds a user to an existing group:

URL entryUrl = new URL( "http://www.google.com/m8/feeds/contacts/
user%40domain.com/full/7fbb8e628be1182a" );
ContactEntry contactEntry = contactsService.getEntry
( entryUrl,ContactEntry.class);

GroupMembershipInfo groupMembershipInfo = new GroupMembershipInfo
();
groupMembershipInfo.setHref("http://www.google.com/m8/feeds/groups/
user%40domain.com/base/5ae379bc0bdda49a");
contactEntry.addGroupMembershipInfo(groupMembershipInfo);
contactEntry.update();

Cheers,
Julian.

Hi Julian,

Thanks for the help! Would you happen to have a working piece of code
lying around which deletes a contact from a group?

Hi Kees,

It is really similar to the one before, get an Entry and call the
delete() function:

URL entryUrl = new URL( "http://www.google.com/m8/feeds/contacts/user
%40domain.com/full/7fbb8e628be1182a" );
ContactEntry contactEntry = contactsService.getEntry
( entryUrl,ContactEntry.class);

contactEntry.delete();

Hi Kees,

Sorry, the example before, is to delete a contact.

You need to edit the List<GroupMembershipInfo> and remove the group,
then update the Contact Entry. For example this removes the first
group:

URL entryUrl = new URL( "http://www.google.com/m8/feeds/contacts/user
%40domain.com/full/7fbb8e628be1182a" );
ContactEntry contactEntry = contactsService.getEntry
( entryUrl,ContactEntry.class);

contactEntry.getGroupMembershipInfos().remove(0);
contactEntry.update();

Hi Julian,

Thanks so much for your help, I've got everything working!

For the record, it might be good for Google to take a look into this:

Since it's pretty popular.

Thanks again!
