Add phone
Values.clear ();
Values.put ("raw_contact_id", ContactID);
Values.put ("MimeType", "vnd.android.cursor.item/phone_v2");
Values.put ("Data2", "2");
Values.put ("Data1", "13671323507");
Resolver.insert (URI, values);
Add Email
Values.clear ();
Values.put ("raw_contact_id", ContactID);
Values.put ("MimeType", "vnd.android.cursor.item/email_v2");
