DEVELOPMENT TOOLS
The Android SDK includes a variety of custom tools that help you 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 in an 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



¢ REAL TIME APPLICATION
¢ A translater for Android
¢ If you are in a country where no one understands your language
¢ You cannot read anything
¢ No aditional device needed
¢ You have your mobile phone
always with you
¢ Uses the google translator
¢ Can be extended with new languages
¢ Adaptive GUI

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)



¢ FINDINGS
¢ Android uses proven technology like Java, XML andLinux
¢ There is an initial learning effort
¢ Android doesn˜t have many of the limitations of current mobile platforms
¢ It offers a rich API for application development
¢ Android is still in beta
¢ Android development is fun
