I need to display contacts in my app. Just like whatsapp, show a small icon on the right for each item in list view.
I create a custom provider to copy the whole contact and register a observer for CRUD. Also I upload all the phone numbers to sever ,checking whether it is registered. My problem is it is rather slow. If delete 5 contacts, my database always keep 1-2 contact undeleted. That because the observer' on change called too frequently. Anyway, my local contact table not always sync with phone native table. And I had to spend a lot effort on sync. Is there any method easier? Or I just read native phone table, and extend the table (adding some extra columns: avatar, status, last login time. etc).？ I know it might involved with syncadapter and account manager, contentprovider. but How to extend that table? or How to set a customize MIME type for existing contact? -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
