Efficient way to load all contacts and all phone numbers (Android 2.0)

It's really slow if you have over 100 contacts (unusable on low end phones), I wondered if I could do a more efficient query.

Snippet from the get Contacts just geting name and lookup key: Uri uri =

I'm trying to form the predicate as in the code below, but obviously that doesn't work. contacts = [contactStore unifiedContactsMatchingPredicate:[NSPredicate predicateWithFormat:@"phoneNumbers <> nil"] keysToFetch:KEYS error:nil]; So, what is the correct way of doing this? Thanks for any help! 回答1: #import <Contacts/Contacts.h> CNContactStore *store = [[CNContactStore alloc] init];
