DEVELOPMENT TOOLS

The Android SDK includes a variety of custom tools that helpyou develop mobile applications on the Android platform.Three

of the most significant tools are:

1.Android Emulator -A virtual mobile device that runs on

our computer -use to design, debug, and test our applications inan actual Android run-time environment

2.Android Development Tools Plugin -for the Eclipse IDE -

adds powerful extensions to the Eclipse integrated environment

3.Dalvik Debug Monitor Service (DDMS) -Integrated with

Dalvik-this tool let us manage processes on an emulator and

assists in debugging

IMPORTANCE HIERARCHY

Foreground Process -required for what the user is currently

doing

Visible Process -holding an Activity - visible to the user on-

screen but not in the foreground(on pause)

Service Process -holding a Service - not directly visible to the

user- relevant tasks

Background Process -holding an Activity - not visible to the

user - can kill at any time(stopped)

Empty Process -doesn't hold any active application

components(as a cache to improve start-up

time)
