INTRODUCTION Android is an open source operating system,
created by Google specifically for use on mobile devices (cell phones and tablets)
Linux based (2.6 kernel)
Can be programmed in C/C++ but most app development is done in Java
Supports Bluetooth, Wi-Fi, and 3G and 4G networking
HISTORY OF ANDROID 2005
Google acquires startup Android Inc. to start Android platform
Work on Dalvik VM begins 2007
Open Handset Alliance announced Early look at SDK
2008 Google sponsors 1st Android Developer Challenge T-Mobile G1 announced SDK 1.0 released
ANDROID ARCHITECTURE
REQUIRMENT FOR ANDROID OS
MINIMUM 32 MB OF RAM
32 MB OF FLASH MEMORY
200MHZ PROCESSOR
SECURITY
Android is a multi-process system, in which eachapplication (and parts of the system) runs in its ownprocess. Most security between applications and thesystem is enforced at the process level through standardLinux facilities, such as user and group IDs that areassigned to applications.

ANDROID INCRESED DAY BY DAY
Android apps can be developed on any platform (Windows XP and Vista, Linux, and Mac OS X) .
Android can support the same hardware as the iPhone: touchscreen, accelerometer, GPS, WiFi, SMS & still camera; plus features that the iPhone doesn’t support: MMS, video camera & bluetooth.
Android is a free OS so an Android-enabled smartphone should be cheaper than a normal smartphone. All the major manufacturers are looking at using it.
Anyone can develop and launch an Android app whereas Apple has strict control of their App Store.
Android has some fresh ideas like Google Maps “street view” and customisable home page

COMPARISON OF ANDROID FROM OTHER OS
BLACK BERRY OS 6 SYMBIAN OS 3ANDROID 2.3
Android 2.3 is loaded with several new colour schemes and various changes have been made in the user interface.
Blackberry OS 6 is having the same professional home screen of its previous version.
Symbian OS 3 is an enhanced version of its previous versions of operating system.
Android support dual core processor.
Black berry is planning to include dual core processor on their smart phones.
Symbian is planning to include dual core processor on their smart phones.
Any mobile manufacture can integrate this operating system in their mobile phones
BlackBerry are available only for their respective manufacturing companies
Symbian are available only for their respective manufacturing companies
ADVANTAGES
Android allows you to access core mobile device functionality throughstandard API calls.
All applications are equal.
Fast and easy development.
Combine information from the web with data on the phone -- such as contacts or geographic location -- to create new user experiences.
Many apps are free or low-cost.
DISADVANTAGES
Making source code available to everyone inevitably invites theattention of black hat hackers.
Open Source.
Platform doesn't run on an encrypted file system and has a vulnerablelog-in.
CONCLUSION Android has been criticized for not being all open-
source software despite what wasannounced by Google. Parts of the SDK are proprietary and closed source, and some believethis is so that Google can control the platform. Software installed by end-users must bewritten in Java, and will not have access to lower level device APIs. This provides end-userswith less control over their phone's functionality than other free and open source phone platforms, such as OpenMoko.With all upcoming applications and mobile services Google Android is stepping into the nextlevel of Mobile Internet. Android participates in many of the successful open source projects.That is, architect the solution for participation and the developers will not only come but will play well together. This is notable contrast with Apple and other companies, where sucharchitecture of participation is clearly belated.The first Android based official devices may well be launched sometime in the early half of 2009. Obviously, that's an age away when it comes to handset design, and Android may wellfind itself competing against the forthcoming Nokia touch screen phones and maybe even the iPhone .
