Android is a mobile operating system developed by Google, based on the Linux kernel and designed primarily for touchscreen mobile devices such as smartphones and tablets. Android's user interface is mainly based on direct manipulation, using touch gestures that loosely correspond to real-world actions, such as swiping, tapping and pinching, to manipulate on-screen objects, along with a virtual keyboard for text input. In addition to touchscreen devices, Google has further developed Android TV for televisions, Android Auto for cars, and Android Wear for wrist watches, each with a specialized user interface. Variants of Android are also used on notebooks, game consoles, digital cameras, and other electronics. Android has the largest installed base of all operating systems (OS) of any kind.Android has been the best selling OS on tablets since 2013, and on smartphones it is dominant by any metric. Initially developed by Android, Inc., which Google bought 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.As of July 2013, the Google Play store has had over one million Android applications ("apps") published – including many "business-class apps"that rival competing mobile platforms – and over 50 billion applications downloaded.An April–May 2013 survey of mobile application developers found that 71% of developers create applications for Android,and a 2015 survey found that 40% of full-time professional developers see Android as their priority target platform, which is comparable to Apple's iOS on 37% with both platforms far above others.In September 2015, Android had 1.4 billion monthly active devices. Android's source code is released by Google under open source licenses, although most Android devices ultimately ship with a combination of open source and proprietary software, including proprietary software required for accessing Google services.Android is popular with technology companies that require a ready-made, low-cost and customizable operating system for high-tech devices.Its open nature has encouraged a large community of developers and enthusiasts to use the open-source code as a foundation for community-driven projects, which deliver updates to older devices, add new features for advanced users or bring Android to devices originally shipped with other operating systems. The success of Android has made it a target for patent (and copyright) litigation as part of the so-called "smartphone wars" between technology companies.

3. History Of Android
• Android Inc. founded in Palo Alto, California, United
States in October 2003.
• Android Develop By:-
• Andy Rubin [Co-Founder of Danger]
• Rich Miner[Co-Founder of Wildfire
Communication Inc.]
• Nick Sears[Once VP at T-mobile]
• Chris White[Headed Design & Interface
Development at Web TV]

4. Introduction Of Android
• It is a open source software platform and operating system for mobile
devices.
• Based on the Linux kernel
• Developed by Google and later the Open Handset Alliance (OHA).
• Allows writing managed code in the Java language
• Android has its own virtual machine i.e. DVM(Dalvik Virtual
Machine) ,which is used for executing the android application.
• Google purchased the initial developer of the software , android
incorporated in 2005.

5. Android Versions

• Nougat (Android 7.0 – Coming Soon)

7. Android Architecture
• Linux Kernel
• Libraries
• Android Runtime
• Application Framework
• Application

9. 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.
• Android is designed having multi layer security which provides flexibility
for this platform.
• When attackers attempt attack on device, android platform help to reduce
the portability of the attack.

10. Security (Cont.)
• There are key components of android security which are described as
follows:
• Design review:-when a security model is designed then it will be
reviewed by the developers so that risk level will be very less
while using the model.
• Code review and penetrating testing:-the goal of this code
review is that in which it will be checked that how the
system will become strong?
• Open source and community review:-android uses open
source technologies that have significant external
review such as Linux kernel.
• Incident response:-android team enables the rapid mitigation of
vulnerabilities to ensure that potential risks to all android users are
minimized.

MATERIAL DESIGN

17. Advantages Of Android
• The ability for anyone to customize the Google Android platform
• It gives you better notification.
• It lets you choose your hardware.
• It has better app market(1,80,000 application)
• A more mature platform
• With the support of many applications, the user can change the screen
display.
• With Google chrome you can open many window at once.
• Supports all Google services.

18. Disadvantages Of Android
• Android Market is less control of the manager, sometimes there are malware.
• Wasteful Batteries, This is because the OS is a lot of "process" in the background
causing the battery quickly drains.
• Sometimes slow device company issued an official version of Android your own .
• Extremely inconsistence in design among apps.
• Very unstable and often hang or crash.

19. Conclusion
• I've learned through my research that Android is a much more diverse operating
system than iOS and Windows Phone Mobile.
• Android has grown rapidly over the past 4 years becoming the most used
smartphone operating system in the world.
• It's because Android doesn't release 1 phone from 1 company with 1 new OS
every year, but countless phones from numerous companies, adding
their own twist, throughout the year, developing gradually day-by-day.
• Android's ability to customize is unparalleled compared to Apple's and
Microsoft's software allowing the user to change and customize nearly every
aspect of Android which most iPhone and Windows 7 users
wouldn't dream possible.
• I am not one to say that Android is better or worse than one OS, but is unique and
incomparable to other mobile operating systems.
