1 David Angulo Rubio ANDROID OS Open Software Platform for Mobile Devices

2 Various OSs for Mobile Devices Google’s Android Apple’s iOS Microsoft’s Windows Phone RIM’s BlackBerry OS

3 ANDROID Open software platform for mobile development A complete stack – OS, Middleware, Applications An Open Handset Alliance (OHA) project Powered by Linux operating system Fast application development in Java Open source under the Apache 2 license

4 BACKGROUND Software platform from Google and the Open Handset Alliance July 2005, Google acquired Android, Inc. November 2007, Open Handset Alliance formed to develop open standards for mobile devices  Google, Intel, Motorola, Nvidia, Samsung, TI, … October 2008, Android available as open source December 2008, 14 new members joined Android project 1.0 : Oct. 2008 2.3 Gingerbread: Dec. 2010 3.0 Honeycomb: Feb. 2011 A tablet-oriented release 3.2 Honeycomb: July 2011 Ice Cream Sandwich :Nov 2011

5 AGENDA Mobile Application Development (MAD) Intro to Android platform Platform architecture Application building blocks Development tools Hello Android

11 Android Project Fields First, the src folder contains your Java source files. The file is the source file for the HelloAndroid activity you specified when you created the project earlier. The file is a special file generated by the ADT to keep track of all the names of views, constants, etc, used in your Android project. You should not modify the content of this file as its content is generated automatically by the ADT. The Android Library contains a file named android.jar. This file contains all the classes that you would use to program an Android application. The res folder contains all the resources used by your Android application. For example, the drawable folder contains a png image file that is used as the icon for your application. The layout folder contains an XML file used to represent the user interface of your Android application. The values folder contains an XML file used to store a list of string constants. The AndroidManifest.xml file is an application configuration file that contains detailed information about your application, such as the number of activities you have in your application, the types of permissions your application needs, the version information of your application, and so on.

13 Advantages There are a lot of advantages that Google’s Android will derive from being an open source software. Some include: The ability for anyone to customize the Google Android platform will open the applications playing small field to small and new players who lack the financial muscle to negotiate wireless carriers like AT&T and Orange The consumer will benefit from having a wide range of mobile applications to choose from since the monopoly will be broken by Google android. Although this will depend on the carrier, one will be able to customize a mobile phone using Google Android platform like never before, right down to the screen. Every feature on the screen can be customized Conclusion We can only hope that the new versions from Android have overcome the actual limitations and that the future possibilities became a reality
