Mobile Operating System
What is Android?

 Android is a software stack for mobile devices that includes an OS, middleware and key applications.
 User applications can be developed using Android SDK which supplies a host of API’s needed for development using Java programming language.
A slice of history
 Google acquired Android Inc.USA in 2005 with establishing OHA.
 Announced Android in 2007 and released source code.
 reached version 2.1 releasing Google’s Nexus.
The architecture.
consists of five software layers:
 Linux;
 Libraries;
 Runtime;
 Application Framework; and
 Applications.
 Linux—the bottom layer is the Linux OS itself—version 2.6.3x .This provides process and memory management, security, networking and an array of relevant device drivers.
 Libraries—
 reside on top of the OS.
 includes Google’s version of standard C system library
(libc), called bionic, and tuned for embedded Linux based devices.
 media and graphics libraries and
SQLite (~500kb
 Runtime—
 on top of the OS, is the Android runtime—the Dalvik VM.
 designed specifically for Android and is register based to conserve memory and maximize performance.
 separate instance of the Dalvik VM is used to execute each Android application.
 The underlying OS is used for memory management and multi-threading.
 Application framework—
 provides a number of services to apps implemented as Java classes.
 Any application can “publish” its capabilities for use by other
 Applications—
 email, SMS, calendar, contacts and Web browser.
 Applications are written in Java.
 processed with the standard Java tools with a converter being used to translate to the Dalvik VM byte codes.
 SQLite:
 powerful and lightweight(approx.225kb) relational database engine (RDBMS).
 SQLite library is linked in an application program.
 The library can be called dynamically.
Application development
 An Eclipse-based development environment is available from Google.
 An Android application consists of a number of resources that are bundled into an archive, an Android package.
 There is no single entry point to a program (like main())

Mobile Operating System

Symbian’s Introduction

The Smartphone operating system Symbian OS is produced by the software development and licensing company Symbian Ltd.

Symbian Ltd was established in June 1998 and is headquartered in Southwark in the UK, and the current CEO is Nigel Clifford.


We had in mind Symbian’s background, the whole history and development behind this operating system, his capabilities, security, performance and so on.

Hardware support and connectivity were, as well, one of our research points.

The native language of the Symbian OS is C++, there for, our research will passes through the programming languages that can be used on Symbian.

The advantages and limitations will be the last tasks we’ll talk about.

Which evolution in the various versions?

Symbian OS 9.1: Change of version 1.2 for the Bluetooth has version 2.0 where the difference is the introduction of an Enhanced Data Rate (EDR) for faster data transfer.

Symbian OS 9.3: The WIFI 802.11 and the HSDPA (High Speed Downlink Packet Access) appear on Symbian OS.

Symbian Os 9.5: This last version includes native-support for mobile digital television broadcasts in DVB-H and ISDB-T formats and also location services.

Software development

What is IDE* ?

An IDE is a software application that allows the computer programmer to develop software for a certain platform. An IDE normally has a: source editor, compiler and/or interpreter and debugger.


Manufacturs point-of-view
Strong Operating System
Established value

Developers point-of-view
Developing for Symbian brings limitations.
A Symbian developer will only develop for Symbian. Is that interesting?
