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

Introduction(2)

What is the Open Handset Alliance (OHA)?

It's a consortium of several companies

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.

Platform(2) Network Connectivity 

It supports wireless communications using:

GSM mobile-phone technology

3G

802.11 Wi-Fi networks

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.

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

Overall Evaluation(2)Limitations

Bluetooth limitationsBluetooth stereoContacts exchangeModem pairingWireless 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

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

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.
