INTRODUCTION: What is Android?
• A software platform and operating system for mobile devices
• Based on the Linux kernel
• Developed by Google and later the Open Handset Alliance (OHA)
• Allows writing managed code in the Java language

WHAT IS OPEN HANDSET ALLIANCE(OHA)• It is devoted to advancing open standards for mobile
devices
• Develop technologies that will significantly lower the cost of developing and distributing mobile devices and services
• It is a constroum of a several companies.

PLATFORM:1. Hardware
Android is not a single piece of hardware; it's a complete, end-to-end software platform that can be adapted to work on any number of hardware configurations. Everything is there, from the boot loader all the way up to the applications.

2. Operating system
• Android uses Linux for its device drivers, memory management, process management, and networking.
• The next level up contains the Android native libraries. They are all written in C/C++ internally, but you’ll be calling them through Java interfaces. In this layer you can find the Surface Manager, 2D and 3D graphics, Media codecs, the SQL database (SQLite), and a native web browser engine (WebKit).
• Dalvik Virtual Machine - Dalvik runs dex files, which
are coverted at compile time from standard class and jar files.

Network Connectivity
• It supports wireless communications using:
GSM mobile-phone technology
3G
802.11 Wi-Fi networks

3.FUTURE POSSIBILITIES:• Google Android Sales to Overtake iPhone in
2012
• The OHA is committed to make their vision a reality: to deploy the Android platform for every mobile operator, handset manufacturers and developers to build innovative devices
• Intel doesn’t want to lose ownership of the netbook market, so they need to prepare for anything, including Android

SOFTWARE DEVLOPMENT: 1. Development requirements
• Java
• Android SDK
• Eclipse IDE (optional)
![Page 13: Aandroid](https://reader035.vdocuments.mx/reader035/viewer/2022070316/555ac7c5d8b42ab1128b5174/html5/thumbnails/13.jpg)
2.IDE and Tools
Android SDK • Class Library• Developer Tools• Emulator and System Images • Documentation and Sample Code
Eclipse IDE + ADT (Android Development Tools) • Reduces Development and Testing Time• Makes User Interface-Creation easier• Makes Application Description Easier

3.PROGRAMMING:
• Java – officially supported
• C/C++ – also possible but not supported

ADVANTAGES:• The ability for anyone to customize the Google Android
platform
• The consumer will benefit from having a wide range of mobile applications to choose from since the monopoly will be broken by Google Android
• Men will be able to customize a mobile phones using Google Android platform like never before
• Features like weather details, opening screen, live RSS feeds and even the icons on the opening screen will be able to be customized
• As a result of many mobile phones carrying Google Android, companies will come up with such innovative products like the location

Limitations Bluetooth limitations
o Android doesn't support: Bluetooth stereo Contacts exchange Modem pairing Wireless keyboards
But it'll work with Bluetooth headsets, but that's about it
Firefox Mobile isn't coming to Android Apps in Android Market need to be programmed with a custom
form of Java Mozilla and the Fennec won't have that
