Remember The Milk Background Synchronization.
- the synchronization process can either happen in the foreground with UI dialogs or in the background with logging to LogCat - UI and dialogs for setting up auto-sync - rename "SynchronizationService" => "SynchronizationProvider", created a service called "SynchronizationService"pull/14/head
