What is Mobile Operating System?

A mobile operating system (mobile OS) is the operatingsystem that controls a Smartphone, tablet, PDA, orother mobile device. Modern mobile operating systemscombine the features of a personal computer operating system

with touch screen, cellular, Bluetooth, Wi-Fi, GPS mobilenavigation, camera, video camera, speech recognition, voicerecorder, music player, Near field communication, personal

digital assistant (PDA), and other features.

Breif intro

Symbian is a mobile operating system (OS) and computingplatform designed for Smart-phones and currently maintained

by Accenture. The Symbian platform is the successor to Symbian OS andNokia Series 60. The latest version is Symbian Belle (original name ofNokia Belle) running on a Nokia N8 was published on YouTube. On

August 24, 2011, Nokia announced it officially for three new smartphones,the Nokia 600 (later replaced by Nokia 603), Nokia 700, and Nokia 701

Symbian OS 6.0 and 6.1 (also called ER6 Bluetooth was addedfor exchanging data over short distances from fixed and mobiledevices. (2002)

Symbian OS 7.0 and 7.0s: This version added EDGE (EnhancedData rates for GSM Evolution) support and IPV6. (2003)

Symbian OS 8.0: There are not great evolution has shared someAPIs to support 3G.

Which evolution in the various versions?

Symbian OS 9.1: Change of version 1.2 for the Bluetooth has version2.0 where the difference is the introduction of an Enhanced DataRate (EDR) for faster data transfer.

11/51

3. Software developmentApplication development

From 2010, Symbian switched to using standard C++ with Qt as themain SDK, which can be used with either Qt Creator or Carbide.c++.Qt supports the older Symbian/S60 3rd (starting with Feature Pack1, aka S60 3.1) and Symbian/S60 5th Edition (aka S60 5.0) releases,as well as the new Symbian platform. It alsosupports Maemo and MeeGo, Windows, Linux and Mac OS X.

Alternative application development can be doneusing Python (see Python for S60), Adobe Flash Lite or Java ME.

Symbian OS previously used a Symbian specific C++ version, alongwith Carbide.c++ integrated development environment (IDE), as thenative application development environment.


12/51

Symbian C++ and SDK

As Symbian OS is written in C++ using Symbian Software's codingstandards, it is naturally possible to develop using Symbian C++,although it is not a standard implementation. Before the release of the

Qt SDK, this was the standard development environment.

There were multiple platforms based on Symbian OS thatprovided software development kit (SDKs) for application fordevelopers wishing to target Symbian OS devices, the main ones beingUIQ and S60. Individual phone products, or families, often had SDKs

or SDK extensions downloadable from the maker's website too.

3 IDEs which to use ?

Carbide C++ CodeWarrior

Visual C++


14/51

Programming languages

Symbian devices can also be programmed using Python, Java ME, Flash Lite, Ruby, .NET, WebRuntime (WRT) Widgets and Standard C/C++.

Symbian OS offers a choice of programming languages to the developer. Symbian OS is

written in C++ , and this is therefore regarded as its primary programming language.


15/51

Programing languagesJava 2nd the most important programing language on SymbianOS.

Others programing languages which you can use on Symbian;JavaSript, Assembler,WMLScript,C# , Visual Basic, OPL and soon


16/51

4. Overall EvaluationConclusion

Manufacturers point-of-view Strong Operating System

Established value

Easy to operate and interactive UI

Developers point-of-view Developing for Symbian brings limitations.

A Symbian developer will only develop for Symbian. Is thatinteresting?

Brief Intro about Android

Android is a Linux-based operating systems for mobile devices such as Smartphone

and Tablet Computers. It is developed by the Open Handset Alliance, led by Google, andother companies.

Android has a large community of developers writing applications ("apps") that extend the

functionality of the devices. Developers write primarily in a customized version of Java.

Apps can be downloaded from third-party sites or through online stores such as Google

Play (formerlyAndroid Market), the app store run by Google. In October 2011, there weremore than 500,000 apps available for Android, and the estimated number of applications

downloaded from the Android Market as of December 2011 exceeded 10 billion.


19/51

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

Possibility to write applications in other languages and compiling it to ARM

native code (support of Google? No)

Unveiling of the Android platform was announced on 5 November 2007 with

the founding of OHA

1. Introduction


20/51

Operating System(s)

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 inC/C++ internally, but youll 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 compiletime from standard class and jar files.
