OS, key applications and middleware.

• Kernel of Android is based on Linux and further furnished by

Google.

• Android can be developed in all versions of Windows System.

3
 ORIGIN

• Founded in October,2003 by 4 Developers in Palo Alto, California:

 Andy Rubin
 Rich Miner
 Nick Sears

 Chris White

Andy Rubin
“…smarter mobile devices that are more aware of its owner’s
location and preferences.”
4
 ORIGIN OF ANDROID (Cont..)

• Android was bought by “Google” in 2005.

• On 5th November,2007 the Open Handset Alliance, a consortium of

several companies was unveiled with the goal to develop “open
standards for mobile services”.

5
 OHA (Open Handset Alliance)
• A business alliance consisting of 47 companies to
develop open standards for mobile devices

6
 PLATFORM

HARDWARE:

• Android is not a single piece of hardware.

• It’s a complete, end-to-end software platform that supports all hardware

configurations.

• Everything is there, from the boot loader all the way up to the applications

7
PLATFORM

8
 PLATFORM
Application:
• Android provides a set of core applications:
• Email
• SMS Program
• Calendar
• Maps
• Browser
• Contacts
• Etc

• All applications are written using the Java language.

9
 PLATFORM
Application framework:

• Developers have full access to the same framework

API(Application Programming Interface)’s used by the core
applications.

• Users are allowed to replace components.

10
 PLATFORM
Libraries:

• Including a set of C/C++ libraries used by components of the

Android system

• Exposed to developers through the Android application

framework

11
 PLATFORM
Android Runtime:

Consist of 2 parts,

1. Core libraries

2. Dalvik Virtual Machine

12
 Android Runtime:

• Core Libraries
 Providing most of the functionality available in Java language.

 APIs
Data Structures
Utilities
File Access
Network Access
Graphics
Etc

13
 Android Runtime:
• Dalvik Virtual Machine

 Providing environment on which every Android application runs

 Dalvik is a software that runs the apps on Android devices.

 Dalvik has been written such that a device can run multiple
VMs efficiently.

14
 Android Runtime:
Dalvik Virtual Machine
 Executing the Dalvik Executable (.dex) format

Suitable for systems that are constrained in terms of

memory and processor speed.

15
 PLATFORM

OPERATING SYSTEM
• Android uses Linux for its device drivers, memory management,
process management and networking.
• Contains Android native libraries. They are all written in C/C++
internally, but calling through Java interfaces,
• In this layer, Surface Manager, 2D and 3D graphics, Media
Codec, and a web browser engine (WebKit).

16
 PLATFORM

NETWORK CONNECTIVITY
It supports wireless communications using :
• GSM mobile-phone technology
• 3G/4G technology
• 802.11 Wi-Fi networks

17
 PLATFORM
SECURITY

• Android is a multi-process system.

• 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.

18
