Use the Accounts & sync settings to manage your Google™ and other supported accounts. You also use these settings to control data synchronization. You can set how and whether each application sends, receives, and syncs data on their own schedules or whether user data is synchronized automatically.
Gmail™, Calendar, and other applications may also have their own settings to control how they synchronize data; see the sections on those applications for details.
Tap Accounts & sync to access the settings below. You can also use this menu to turn on the sync function (checkmark the Auto-sync data checkbox) or add a new account (tap ADD ACCOUNT at the bottom of the screen).
ACCOUNTS
Displays a list of all of your accounts, including your Google Account. Tap one of the entries to access their settings.
