This document provides an introduction to Android development. It discusses how Android was started by Google acquiring Android Inc. in 2005. It also overviewed some of the major Android versions and noted that over 500 million Android devices have been activated. The document reviews setting up an IDE like Eclipse for Android development and walks through creating a basic "Hello World" Android project. It outlines the key building blocks of Android apps like activities, intents, services, and broadcast receivers. Finally, it encourages learning by starting a project today and provides some resource recommendations for learning more about Android development.
