How to update an existing object

Android
1

Hey, I have table Relationship. It has columns Person ( 1-1 to Person Table) and Friends(1-N to Person table). I got in Android list of all friends i.e.

List<Person> friends

I added one more person to that list:

 friends.add(newPerson);

and updated Relationship class:
relationship.setFriends(friends);

and now I want to update it on sarver:



relationship.saveAsync(new AsyncCallback<Relationship>() {
 public void handleResponse(Relationship savedContact) {
 Log.v("It works", "It works");
 }


 @Override
 public void handleFault(BackendlessFault backendlessFault) {
 Log.v("Nooo,it doesn't work", backendlessFault.toString());
 }
 });
}

I got this exception: BackendlessFault{ code: ‘36’, message: ‘Duplicate entry for column ‘user’’ }

Any updates on this? I’m getting the same issue? …The docs don’t help in this case.
