7. 1. INTRODUCTION
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.
Research
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.

8. 2. PLATFORM
Network Connectivity
 Evolution in the various versions
 Symbian OS 6.0 and 6.1 (also called ER6 ): Bluetooth was
added for exchanging data over short distances from fixed and
mobile devices. (2002)
 Symbian OS 7.0 and 7.0s: This version added EDGE
(Enhanced Data rates for GSM Evolution) support and IPV6.
(2003)
 Symbian OS 8.0: There are not great evolution has shared
some API’s to support 3G.

9. 2. PLATFORM
Network Connectivity
 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.

10. 2. PLATFORM
This Operating System is used in
Nokia’s mobiles

11. 3. SOFTWARE DEVELOPMENT
Development requirements
 The right SDK
 S60
 UIQ
 MOAP
 The IDE-tool of your choice

12. 3. SOFTWARE DEVELOPMENT
Which IDE ?
 Carbide C++
 CodeWarrior
 Visual C++

13. PROGRAMING LANGUAGES
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.

14. PROGRAMING LANGUAGES
 Java 2nd the most important programing language on
Symbian OS.
 Others programing languages which you can use on
Symbian;
JavaSript, Assembler,WMLScript,C# , Visual Basic, OPL and
so on…

17. 1. 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
• 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

18. 2. Platform
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 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.

19. 2. Platform
Network Connectivity
It supports wireless communications using:
 GSM mobile-phone technology
 3G
 Edge
 802.11 Wi-Fi networks

20. 2. Platform
Security
Android is a multi-process system, in which each application (and parts of the
system) runs in its own process. Most security between applications and the
system is enforced at the process level through standard Linux facilities, such as
user and group IDs that are assigned to applications.
Additional finer-grained security features are provided through a "permission"
mechanism that enforces restrictions on the specific operations that a particular
process can perform, and per-URI permissions for granting ad-hoc access to
specific pieces of data.

21. 2. Platform
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
• More Android devices are coming and some will push the envelope even
further

22. 2. Platform
This Operating System is used in Samsung, Sony, Motorola and
HTC mobiles.

23. 3. Software development
Programming Language(s)
• Java – officially supported
• C/C++ – also possible but not supported
