Manage applications
Touch to manage and remove installed applications.
Running services
Touch to open a list of services—applications or parts of applications
that provide services to other applications, or that run even when their
main application isn’t running. Examples include the Android onscreen
keyboard and the small portion of Google Talk that always listens for
incoming messages. Above each service, one or more gray bars show
what processes the running service needs and how much memory they're
using (how much memory you would recover if you stopped the service).
Depending on the service, when you touch it in the list it either opens a
dialog in which you can stop it or opens its Settings screen.
Storage use
Touch to view available memory and the memory used by applications on
your phone.
Battery use
Touch to view the amount of power consumed by your phone. It also
shows which applications consume the most battery power. For more
information, refer to section 11.15 About phone.
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 checkbox to permit debugging tools on a
computer to communicate with your phone via a USB connection.
Stay awake:• mark the checkbox 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 checkbox 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 & sync11.7
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.
