The google sync of Contacts, Calendars, Gmails seems to work differently from the user apps that, dealing with the content providers.
I created a app that can add contacts from my own backend server, using the Contacts Content Provider, but the performance is terrible. And, force to set the "_sync_account" field to "my_local_account_xxxx". It takes about 1 second to insert / update / delete one record from the Contacts database. But after a online sync with google these records disappered. So, I'm wondering how to get these works done in a better way just like the google sync do. Can you give me some tips / advice on where to start. -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
