Development
The Development screen contains settings that are useful for developing
Android applications. For full information, including documentation of the
Android applications and development tools, see the Android developer
web site (http://developer.android.com).
USB debugging:• mark the check box to permit debugging tools on a
computer to communicate with your phone via a USB connection.
Stay awake:• mark the check box to prevent the screen from dimming
and locking when the phone is connected to a charger or to a USB
device that provides power. Don’t use this setting with a static image on
the phone for long periods of time, or the screen may be marked with
that image.
Allow mock locations:• mark the check box to permit a development
tool on a computer to control where the phone believes it is located,
rather than using the phone’s own internal tools for this purpose.
Accounts & sync10.9
Use the Accounts & Sync settings to add, remove, and manage your Google
and other supported accounts. You also use these settings to control how
and whether all applications send, receive, and synchronize data on their
own schedules, and whether all applications can synchronize user data
automatically.
Gmail, Google Calendar, and other applications may also have their own
settings to control how they synchronize data; see the sections on those
applications for details.
General sync settings10.9.1
Background data
Mark the check box to permit applications to synchronize data in the
background, whether or not you are actively working in them. Unmarking
this setting can save battery power and lowers (but does not eliminate)
data use.
Auto-sync
Mark the check box to permit applications to synchronize data on their
own schedule. If you unmark this setting, you must touch an account in the
list on this screen, touch Sync now to synchronize data for that account.
Synchronizing data automatically is disabled if Background data is
unchecked. In that case, the Auto-sync checkbox is dimmed.
