Updating a Contact Phone Number in Android

pepe USMember


I am having a bit of trouble updating all a particular contact entry. At the moment I am able to edit the first and last name, but I am unable to edit the phone number or email without having some undesired consequences like renaming all the contacts on my phone including their number/email/name :-( I think that was due to my selection not clarifying the mimetype in the selection.

At the moment I am have a cursor that gets the data id - ContactsContract.Data.InterfaceConsts.Id and I use this as the condition when selecting which contact to update. I wanted to use ContactsContract.Contacts.InterfaceConsts.Id, but this doesnt seem to let me access the phone or email or name (other than display name).

I then use the data id as follows:

`List ops = new List();

            String where = ContactsContract.Data.InterfaceConsts.Id + " = ? AND " +
                    ContactsContract.Data.InterfaceConsts.Mimetype + " = ? ";

            String[] p = new String[] {

            ContentProviderOperation.Builder builder = ContentProviderOperation.NewUpdate(ContactsContract.Data.ContentUri);
            //builder.WithSelection(ContactsContract.CommonDataKinds.StructuredName.DisplayName + " LIKE '%" + _Contact.DisplayName + "%'", null);
            //builder.WithSelection(ContactsContract.Data.InterfaceConsts.Id + " LIKE '%" + _Contact.DataId + "%'", null);
            builder.WithSelection(where, p);
            builder.WithValue(ContactsContract.CommonDataKinds.StructuredName.GivenName, _Contact.FirstName);
            builder.WithValue(ContactsContract.CommonDataKinds.StructuredName.FamilyName, _Contact.LastName);

            String wherey = ContactsContract.Data.InterfaceConsts.Id + " = ? AND " +
                       ContactsContract.Data.InterfaceConsts.Mimetype + " = ? ";

            String[] py = new String[] { _Contact.DataId.ToString(),

            builder = ContentProviderOperation.NewUpdate(ContactsContract.Data.ContentUri);
            builder.WithSelection(wherey, py);
            builder.WithValue(ContactsContract.CommonDataKinds.Phone.Number, "999999999");

            // Update the contact
            ContentProviderResult[] result;

                result = ContentResolver.ApplyBatch(ContactsContract.Authority, ops);
            catch (Exception e) { System.Diagnostics.Debug.WriteLine("this is the error...................." + e.Message); }


This code lets me update the first and second name but does nothing to the phone number :-(

I am completely lost at the moment, so any help would be greatly appreciated.
