WHAT IS SMART SMARTPHONE?

While there is no standard definition of the term

"smartphone" across the industry, but usually, any

phone which does more things than the normal cell

phone does is categorized as smart phone.

Asmartphone is a mobile phone that offers more

advanced computing ability and connectivity .

We can think of a smartphone like a miniaturecomputer that can also place and receive calls.

CONTINUED

Smart phones run complete operating system softwareproviding a platform for application development.

While almost all cell phones include some sort of

software, a smartphone will have the ability to domore.

It may allow you to create and edit Microsoft Office

documents--or at least view the files.

Or it may allow you to edit photos, get driving

directions via GPS, and create a playlist of digital

tunes.

KEY SMARTPHONE FEATURES:

Operating System: In general, a smartphone will be

based on an operating system that allows it to run

productivity applications.

Software: Smart phones are equipped with muchmore software applications, and offer many features,

which enlarges the purpose area to Internet access,

digital photography, GPS and other areas.

Messaging:All cell phones can send and receive text

messages, but what sets a smartphone apart is its

better handling of e-mails.


5/31

CONTINUED

Web Access: Smartphones can access the Web at

higher speeds, thanks to the growth of 3G data

networks and the addition of Wi-Fi support to many

handsets.

QWERTY Keyboard: Many cell phones now have full

QWERTYkeyboards, but this is a basic requirement

for smartphones.

INCREASING MARKET SHARE OF SMARTPHONES :

According to figures for 2010 released by Gartner,

smartphones accounted 19% of the mobile phones sold

that year. That's 72.1% more sales than in 2009.

The Coda Research Consultancy predict globalsmartphone sales of some 2.5 billion over the 2010-

2015 period.

Mobile Internet use via smartphones will increase 50

fold by the end of that period.

Morgan Stanley Research estimates sales of

smartphones will exceed those of PCs in 2012.

NEED OF SMARTPHONE DEVELOPMENT?

In a remarkably short timeframe, developing apps for

smartphones has gone from an arcane curiosity to an

essential skill set.

Employers are scrambling to find developers capable of

transforming their ideas into apps.

As a result industry need for smartphone developers is

increasing at a rapid pace.

DIFFERENT SMARTPHONE OS PLATFORMS:

There are a plethora of platform possibilities:

y Googles Android

Developed by Google.

Market leader having more than 33% share.

Supports Multitasking. More than 1,00,000 apps available.

y iPhone OS

Developed by Apple Inc.

Simple and elegant. Supports Multitasking.

More than 3,50,000 apps available


9/31

CONTINUED

y Windows Mobile Developed by Microsoft.

Newer than iOS and Android.

Fewer apps available, not app centric.

Little market share.

y RIMs BlackBerry Less development support available.

Though older than iOS and Android, only around 20,000

apps available.

Decreasing market share.

y Samsungs Bada Newest OS in field.

Lacks multitasking.

Little market share.

WHICH PLATFORM A DEVELOPER SHOULD OPT?

A detailed examination of so many platforms is impractical

here, so I have decided to concentrate on two of the leading

platforms, Google's Android and Apple's iOS.

We will compare their hardware/operating system

requirements, Software Development Kits (tools,

frameworks, languages, documentation),instructor

resources, and finish up by describing the development of a

s on both platforms.

1.HARDWARE/OS REQUIREMENTS


12/31

IOS

Intel based Macintosh

Computer. Mac OS X 10.6 (Snow

Leopard).


13/31

ANDROID

Unlike iOS, which is

restricted to Mac OS X,

Android apps can be

developed using any of the

current major operating

systems, Windows (XP or

higher), Mac OS X (10.5.8

or higher), and Linux

systems (running withkernel 2.6 or higher).


14/31

2.SOFTWARE DEVELOPMENT KIT


15/31

IOS

iOS apps are written using Xcode, a modern IDEused to code, debug, and lay out the interface.

iOS applications are most commonly written

using Objective-C, a superset of ANSI-C thatborrows its OO syntax from SmallTalk.

The iOS simulator lets you build and run youriPhone or iPad application on your computer.

The simulator application presents the iPhone oriPad user interface in a window on yourcomputer.


16/31

CONTINUED

The first step towards testing our applications on areal device is to sign up for the iPhone Developer

Program at

http://developer.apple.com/iphone/program/.

There are two programs available - Standard and

Enterprise. For most developers wanting to release

applications on the App Store, they can simply sign up

for the Standard program, which costs US$99 per year.

In an Xcode project, the interface is specified in a .xib

file, and the implementation in an Objective-C class.


17/31

CONTINUED

Creating the Project:

y When creating a new project in Xcode, the user

is offered multiple templates. We choose one

according to our need, a Viewbasedapplication, targeted for the iPhone. The

template provides:

A single view, stored in a .xib file, on which we

graphically lay out the interface elements of the

project;


18/31

CONTINUED

a view controller, stored as code in a .h (header) and

.m(implementation) file, which plays its customary

role as an intermediary between the view and model;

and

A .plist (property list) file, in which we define the

app's name, and icon, and other items.

However, people must deal with memory management

themselves for performance reasons garbage

collection is not available.


19/31

ANDROID

The Android software development kit (SDK)

includes a comprehensive set of development

tools. These include a debugger, libraries, a

handset emulator, documentation, sample code,

and tutorials. Eclipse is the recommended and most popular

development environment for Android.

The GUI layout for an Android app consists ofXML files which include Layout and View

elements.


20/31

CONTINUED

An Android project has three main elements:

y Manifest file detailing its internal organization,

y Resources, such as images and files, and

y

The main Activity and associated class files.

The directory hierarchy and a basic template for all

three elements are created when a new project is

begun in Eclipse.

CONCLUSION

Both iOS and Android have their advantages.

iOS development requires a specific type of

hardware that may be more difficult to obtain but

it gives exposure to another operating system.

On the other hand Android development can take

place in any modestly equipped computer science

laboratory. The iOS gives advantage to exposing

professionals to a relatively novel language and

development environment.


28/31

CONTINUED

Developers have to deal with memory managementissues in iOS.

But there can be no denying that students studying

Android will likely know Java; students studying iOS

will very likely not know Objective-C.

Both are capable of 2D and 3D graphics with OpenGL

and database management with SQLite.

Computing on mobile devices is mushrooming, and

regardless of platform choice there are enough

opportunities for the developers to make their careerin this relatively new field of application

development, and make for an exciting professional

experience
