History of Android OS

• Android was founded by a company, named Android Inc. in Palo

Alto of California, U.S. in 2003 whose founder was Andy Rubin.

• Early intentions of the company was to develop an advanced

operating system for digital cameras, but then it was realised that

market for such devices was not large enough so they diverted

their attention to producing a Smartphone operating system.

• Android was then acquired by the Google in 2005 for US50 million

$ and unveiled its distribution in 2007 with formation of Open

Handset Alliance led by Google.

• The first commercially available phone to run Android was the HTC

Dream, released on October 22, 2008 With Android Version 1.0

Open Handset Alliance (OHA)

The Open Handset Alliance (OHA) is a group of companies Which are allowed to use source code of Android and develop applications.

The OHA was established on 6 November 2007, led by Google with 47 members including mobile handset makers, application developers and chip makers.

In OHA group companies are allowed to use source code of Android and develop applications according to the needs of customers.

Major group members of OHA group is Google , HTC, Sony, Dell , Intel, Samsung, Nvidia, LG etc.

Revolution in Mobile Experience

• Before invention of mobile OS, only technological device that

required an operating system was a personal computer. Initially it

was just one or two high-end mobile phones that ran on operating

systems, but with the success of those particular models, more

models started using Smartphone operating systems.

• One Smartphone operating system that has truly revolutionized

the whole idea of a mobile phone is Android. The first mobile

phone to run on android OS was ‘HTC DREAM’. After the

success of Android based HTC(Dream), more and more

Smartphone manufacturers joined the android project and the

members of the Open Handset Alliance (OHA) increased. This

resulted in Android becoming the most widely used Smartphone

OS in the market.

Revolution in Mobile Experience

• The open source and flexible nature of Android allows the

developers and device manufacturers to modify the software

according to their needs, As a result of this constant

development and innovation, Android has been adapted to work

on technological devices other than smart phones.

• Android devices are much more cost effective than its rivals and

offer a more stimulating and fulfilling user experience, thus,

making Android the most preferred choice by users.

• Android has become the core operating systems of many other

devices like Smart books , Wristwatches , Car, CD/DVD players

, Camera and other devices

minimum, so more battery.

Android Rooting

Android Rooting is the process of allowing users of devices

running Android OS to attain privileged control, also known

as root access, of their android system.

It is performed with the goal of overcoming limitations that

manufacturers put on their devices, resulting in the ability to

replace device’s operating system or perform other

operations that are otherwise inaccessible to a normal

android user.

Many manufacturers have tried to make “unrootable” devices

with harsher protections but they are usually still rootable in

some way. There may be no root available for a new device,

but one is usually available in a few weeks.

Limitations of Android OS

Android requires an active internet connection. At least there

should be a GPRS internet connection so that the device is

ready to go online according to our needs.

Application in the Android phones can easily be obtained and

for free, but the consequences in each of these applications,

will always be ads on display, either the top or bottom of the

application.

Android operating system has a lot of "process" running in the

background that lead to the quick battery drains.

Making source code available to everyone inevitably invites

the attention of hackers and less secure than other mobile

OS.

Fact & Figure about Android OS

Fact & Figure about Android OS

Android was about to close. After the company was founded,

it became difficult for the founder to keep it floating and to

carry out daily business operations. Steve Perlman, a friend

of Andy Rubin, saved the company by infusing much needed

funds.

Microsoft considered it a very underrated project and they

thought that android cannot make a big hit.

The logo of android was inspired from a character of 1990’s

game called ‘Gauntlet - The Third Encounter’.

Android space- in 2010 a British satellite firm launched a

nexus S into space which controls satellite and collects

information.

Future Scope of Android OS

Customers are always demanding something new and innovative. That’s the reason all companies are shifting from those boring phones to much more interesting android phones with lots of new exclusive content.

Google will launch another version of Android that starts with ‘L’ because Google launches all its android versions in the alphabetical order with upgraded and new features.

More future development of smart watches, digital cameras and other devices with Android OS. There are chances of Android becoming the widely used operating system in world in almost every kind of technology.

Mobile Apps development industries are considering Android Application Development as one of the best remunerative business opportunities.

Future Scope of Android OS

Android introduced some innovative and new features

with every new version and try to overcome it’s

drawback in previous version.

Many companies are now working just on developing

android based applications.

There has been an unexpected rise in the demands of

the android developers and this demand is expected to

increase in future.

Future of android is beyond imagination. There seems

to be no end to evolving new applications and mobiles

using android technology.
