  2. INTRODUCTION What is Android? • Android is a mobile operating system developed by Google and is based upon the Linux kernel and GNU software. • It was initially developed by Android Inc. (a firm purchased by Google) and later positioned in the Open Handset Alliance.

  3. ANDROID ARCHITECTURE

  4. HISTORY • Acquisition by Google • In July 2005, Google acquired Android, Inc., a small startup company based in Palo Alto, California, USA. • This began rumours that Google was planning to enter the mobile phone market.

  5. Open handset alliance • Devoted to advancing open standards for mobile devices • Develop technologies that will significantly lower the cost of developing and distributing mobile devices and services

  6. What is the Open Handset Alliance (OHA)? • →It's a consortium of several companies

  7. Features • Handset layouts • Storage • Connectivity • Messaging • Web browser • Java support • Media support • Streaming media support • Additional hardware support • Development environment • Multi-touch • Bluetooth • Multitasking • Tethering

  8. PLATFORM Hardware Android is not a single piece of hardware; it's a complete, end-to-end software platform that can be adapted to work on any number of hardware configurations. Everything is there, from the bootloader all the way up to the applications.

  9. Operating System(s) • Android uses Linux for its device drivers, memory management, process management, and networking. • The next level up contains the Android native libraries. They are all written in C/C++ internally, but you’ll be calling them through Java interfaces. In this layer you can find the Surface Manager, 2D and 3D graphics, Media codecs, the SQL database (SQLite), and a native web browser engine (WebKit).

  10. Network Connectivity  • It supports wireless communications using: • GSM mobile-phone technology • 3G • Edge • 802.11 Wi-Fi networks

  11. Security Android is a multi-process system, in which each application (and parts of the system) runs in its own process. Most security between applications and the system is enforced at the process level through standard Linux facilities, such as user and group IDs that are assigned to applications. Additional finer-grained security features are provided through a "permission" mechanism that enforces restrictions on the specific operations that a particular process can perform, and per-URI permissions for granting ad-hoc access to specific pieces of data.

  12. Future possibilities • Google Android Sales to Overtake iPhone in 2012 • Intel doesn’t want to lose ownership of the netbook market, so they need to prepare for anything, including Android • More Android devices are coming and some will push the envelope even further

  13. Software development • The early feedback on developing applications for the Android platform was mixed. •  Issues cited include bugs, lack of documentation, inadequate QA infrastructure, and no public issue-tracking system. (Google announced an issue tracker on 18 January 2008.) • The Android SDK includes a comprehensive set of development tools.

  14. Google applications • Google has also participated in the Android Market by offering several applications for its services. • In mid August 2010 Google launched "Voice Actions for Android", an innovative feature to its set of applications..

  15. Marketing Logos: • The Android logo was designed with the Droid font family made by Ascender Corporation.

  16. VERSIONS

  17. ADVANTAGES OF ANDROID • Android can Run Multiple Apps at the Same Time. • Android Keeps Information Visible on Your Home Screen. • Android Has a Better App Market. • Android Lets You Choose Your Hardware. • Android Lets You Choose Your Carrier. • Android Lets You Change Your Settings Faster. • Android Does Google and Social Integration. • Android Gives You More Options to Fit Your Budget.

  18. Limitations • Bluetooth limitations • Android doesn't support: • Bluetooth stereo • Contacts exchange • Modem pairing • Wireless keyboards But it'll work with Bluetooth headsets, but that's about it

  19. CONCLUSION We can only hope that the next versions of Android have overcome the actual limitations and that the future possibilities became a reality.
