4 Meet the Android  The Android phone platform is built on a free operating system created by a company called Android Inc.  In 2005, Google bought Android, Inc Open Source - is computer software that is available with source code: the source code and certain other rights normally reserved for copyright holders are provided under an open-source license that permits users to study, change, improve and at times also to distribute the software.  Android is the first open-source technology platform for mobile devices. Open Handset Alliance – An open-source business alliance of 80 firms that develop open standards for mobile devices.

5 Open Source  The strength of open source is the ability to share their source code to be improved upon.  Open source Android software is free.  The Android open-source platform allows more freedom so people can collaborate and improve the source code.  Many phone manufactures install Android OS due to its open- source environment and the companies don’t have to pay license fees and royalties. This allow them to sell their devices cheaper.  Android has a large community of developers writing apps that extend the functionality of the device

6 Android Phone Device  Androisd phone devices are sold under a variety of names  EVO, DROID X, Galaxy, Echo, Optimus, Xperia, Cliq, Inspire, Thunderbolt, Atrix, Desire, Nexus, Infuse, Pyramid, and Revolution.  Nook from Barnes and Noble uses an Android OS

You can close those apps to free up the phone’s processor memory, extending the battery power. Optimized Gaming – Android supports the use of gyroscope, gravity, barometric sensors, linear acceleration, and rotation vector, which provide game developers with highly sensitive and responsive. Onscreen Keyboard – The onscreen keyboard offers suggestions for spelling corrections as well as options for completing words you start typing. The onscreen keyboard also supports a voice-input mode.

Facial Recognition – Android provides this high-level feature for automatically identifying or verifying a person’s face from a digital image or a video frame.

9 Writing Android Apps  Java Language – An object-oriented programming language and a platform originated by Sun Microsystems.  Object-Oriented Programming (OOP) - is a programming paradigm using "objects" – usually instances of a class – consisting of data fields and methods together with their interactions – to design applications and computer programs.  Eclipse (IDE) – application development tool used to write programs.  XML – Extensible Markup language is used to assist in the layout of the Android emulator.

10 Android Emulator  The Android Emulator lets you design, develop, prototype, and test Android applications without a physical device.  The mouse is used to simulate a touch of the screen.  The emulator mimics almost every feature of a real Android handset except for the ability to place a voice call.  A running emulator can play video, audio, gaming animation, and store information.  Multiple emulators are available within the Android SDK
