Android Study Guide
Android (operating system)
Android is a Linux-based operating system designed primarily for touch screen mobile devices such as smart phones and tablet computers.
An open source Linux-based operating system intended for mobile computing platforms
Includes a Java API for developing applications
It is not a device or product
Initially developed by Android, Inc., whom Google financially backed and later purchased in 2005, Android was unveiled in 2007 along with the founding of the Open Handset Alliance: a consortium of hardware, software, and telecommunication companies devoted to advancing open standards for mobile devices. The first Android-powered phone was sold in October 2008.
Android is open source and Google releases the code under the Apache License.
This open source code and permissive licensing allows the software to be freely modified and distributed by device manufacturers, wireless carriers and enthusiast developers.
Additionally, Android has a large community of developers writing applications ("apps") that extend the functionality of devices, written primarily in a customized version of the Java programming language.
Android, an open source operating system for mobile devices (Smartphone and tablet), led by Google. The Android SDK provides a set of tools and APIs to develop Android applications, using Java. So, if you know Java, Android programming is easy.
