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
applications aren’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.

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).

computer to communicate with your phone via a USB connection.

locking when the phone is connected to a charger or to a USB device that

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.
