15. Why Android OS?
• Why is Android the popular choice?
• Android’s popularity as the ideal OS for smart phones is
increasing because of one simple reason: No other
platform provides as many applications for free!
• No doubt, the market is flooded with jobs in field of
application development in iOS, Blackberry, Symbian and
other platforms as well, but the open-source nature of
Android definitely adds to its appeal.
• It is because of this kind of consumer demand
that so many tech firms are actively seeking
talented Android developers. Consumer today knows
his/her requirements, and wants a handy application to
take care of it.

16. Why Android OS?
• Android is an open marketplace where you
can create games and applications with the
world class platform for your mobile
devices. Ex., Tablets, Phones
• The latest stable version of the android OS
is JellyBean 4.3 which is API level 18 and
it was released on July 24, 2013.
• Kitkat 4.4 is about to be released.

18. Android OS applications
• Native Applications: The most basic way to build apps
for mobile devices is to write them for a specific kind of device. For
instance, iPhone apps are written in Objective-C, Android apps in
Java, etc.
• Mobile-Optimised Web Apps: They’re usually just
a condensed version of the usual website, resized to fit a smartphone
screen.
• Hybrid Applications: Hybrid apps are web apps built
into a native mobile framework. This essentially means that they
take advantage of the cross-compatibility of web technologies such
as HTML5, CSS and Javascript.
