Android is an open source software platform and operating system for mobile devices based on the Linux kernel. It has seen several updates since its original release, including Cupcake, Donut, Eclair, and others. Android allows developers to publish applications to the Android Market without approval, unlike Apple's App Store which requires a month-long approval process. The Android SDK includes development tools like an emulator, plugins for the Eclipse IDE, and DDMS for debugging applications in the Android runtime environment.

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: 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.
