2. Main Topics
1. Introduction
2. Platform
3. Development
4. Versions
5. Overall Evaluation

3. Introduction(1)
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
Unveiling of the Android platform was
announced on 5 November 2007 with the
founding of OHA

4. Introduction(2)
What is the Open Handset Alliance (OHA)?
It's a consortium of several companies

5. Platform(1)
Operating System(s)
Android uses Linux for its device drivers, memory
management, process management, and
networking.
Android native libraries. They are all written in
C/C++ internally, but you’ll be calling them through
Java interfaces.

6. Platform(2)
Network Connectivity
It supports wireless communications using:
GSM mobile-phone technology
3G
802.11 Wi-Fi networks

7. Platform(3)
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.

8. Development
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

12. Overall Evaluation(1)
Advantages
Some of the advantages include:
The ability for anyone to customize the Google
Android platform
Wide range of mobile applications to choose
Customize a mobile phones using Google Android
platform like never before
Features like weather details, opening screen, even
the icons on the opening screen will be able to be
customized
Offer online real time multiplayer games

13. Overall Evaluation(2)
Limitations
Bluetooth limitations
Bluetooth stereo
Contacts exchange
Modem pairing
Wireless keyboards
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

14. Overall Evaluation(3)
Future possibilities
Intel doesn’t want to lose ownership of the
netbook market, so they need to prepare for
anything, including Android
Fujitsu launched an initiative to offer consulting
and engineering expertise to help run Android on
embedded hardware
More Android devices are coming and some will
push the envelope even further

15. Overall Evaluation(4)
Conclusion
We can only hope that the next versions of
Android have overcome the actual limitations
and that the future possibilities became a reality.
