10. Application building blocks
 Activity
 IntentReceiver
 Service
 ContentProvider

11. DEVELOPMENT TOOL
 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
 Android Development Tools Plugin -for the
Eclipse IDE – adds powerful extensions to the Eclipse
integrated environment
 Dalvik Debug Monitor Service (DDMS) -
Integrated with Dalvik-this tool let us manage
processes on an emulator and assists in debugging
