INTRODUCTIONWhat is Android?

A software platform and operating system for mobile devices.

Based on the Linux kernel. Allows writing managed code in the Java language. Developed by Google and later the Open Handset Alliance

(OHA). Unveiling of the Android platform was announced on 5

November 2007 with the founding of OHA.

WHAT IS THE OPEN HANDSET ALLIANCE (OHA)

It's a consortium of 86 H/W ,S/W and telecommunications companies.

Devoted to advancing open standards for mobile devices. Develop technologies that will significantly lower the cost of

developing and distributing mobile devices and services. Write apps to run on mobile phones.

WHAT IS THE OPEN HANDSET ALLIANCE (OHA)

License:- Android is under version 2 of the Apache Software License (ASL).

VERSIONS OF ANDROID

NOTE:- API Level is an integer value that uniquely identifies the framework API revision offered by a version of the Android platform.

1: Software fragmentation:- Simply put, there are too many versions of the Android operating system in circulation. This means that developers can’t just focus on the most recent versions of the OS.

Not everyone has upgraded. It’s not easy for users to upgrade their operating systems, and carriers have little incentive to do so.

For example, we bought an Android phone in February 2011 that came equipped with Android 2.1. Version 2.2 had been released way back in July of 2010!

2: Hardware fragmentation:-

User of android is usually faces the Hardware problems which will affected the Throughput speed.

For example Button A on Handset 1 does Function X. The problem? Button A on Handset 2 does Function Y. Here’s a look at the variety of button configurations. So obviously, you can’t design an app that relies on Button A to do the same thing for everyone. Users may grow frustrated and give up on an app that doesn’t perform intuitively.

3:Security Issues:-

PROBLEM’S WITH ANDROID SYSTEM

Lack of governance in the Android market has led to a proliferation of malware programs that can masquerade as trusted apps.

The openness of Android has made it susceptible to attack. To make matters worse, unlike traditional open source software.

Fragmentation on Android makes it difficult to roll out fixes. It’s hard to keep customers happy and retain trust when security problems can’t be fixed quickly.

4:Market Research Cost:- As mentioned, understanding your customer is the key to getting an Android app right. This, of course, requires lots of research into how customers use the software and hardware on their phones. And, yes, that takes time and can therefore be an expensive endeavor for developers to undertake.

PROBLEM’S WITH ANDROID SYSTEM5:Some other Problems:- CPU typically run 500-600 Mhz.

Ram available to an App may only be few Megabytes.

Disk (flash) access is very Slow.

Network access may be slow or (very) intermittent.

Sometimes gives illusion that Apps is running while the apps was closed.Too much Google dependent.

ANDROID TECHNOLOGIES

Introducing several technologies like:-

Amazing Photo Sphere- Up, down and all around you, it’s like no camera we’ve ever seen. With Android 4.2, snap pictures in every direction that come together into incredible, immersive photo spheres that put you right inside the scene.

We can also View our photo spheres right on your phone, share them on Google+ with your friends and family, or even add them to Google Maps for the world to see.

A smarter keyboard, now with Gesture Typing

ANDROID TECHNOLOGIES

Writing messages on the go is easier than ever with Gesture Typing – just glide your finger over the letters you want to type, and lift after each word. You don’t have to worry about spaces because they’re added automatically for you.

ANDROID TECHNOLOGIESOne Tablet many Users

It’s your fully customized tablet. And theirs, too. With support for multiple users, you can give each person their own space. Everyone can have their own home screen, background, widgets, apps and games – even individual high scores and levels!

WHAT NEXT IN ANDROID Android stats continue to be surprising: 400 million activated Android devices,400,000 Android devices activated every day, 200,000 apps in the Android Market, 4.5 billion apps downloaded from the Android Market.

The next major Android release is called Ice Cream Sandwich and the goal is to create a unified operating system that runs on phones, tablets and TVs. Ice Cream Sandwich will be released later this year.

COMPARATIVE STUDY

The figures are in: In the third quarter of 2012, no less than 75% of smartphones shipped ran Google’s Android operating system. This equates to 400 million Android handsets, almost tripling the 125 million Android smartphones from the same quarter last year. If we look at the entirety of 2012 to date, 74.2% of smartphones sold are powered by Android, up from 49.2% last year.
