Creating the service object efficiently It can be expensive, in terms of both memory consumption and processing cost, to create the service objects that your app needs to interact with the corresponding databases. This new functionality will enable you to sync your handheld's built-in address book with your Gmail contacts.This all happens in the background and over the air, so your information is always up to date, no matter where you are or what you're doing.You should avoid creating service objects every time you need to perform operations on the database.
Instead, try to create the object only once and use the same object throughout your app.
Current and new Google Sync users can try Google Sync today by visiting m.google.com/sync from their Black Berry browser.
