System Architecture

10. 1028/04/2015 Android
System Architecture (Cont.)
Android software Stack

11. 1128/04/2015 Android
System Architecture (Cont.)
Android software Stack- Applications
 Android provides a set of core applications:
 Email Client
 SMS Program
 Calendar
 Maps
 Browser
 Contacts
 Etc
 All applications are written using the Java language.

12. 1228/04/2015 Android
System Architecture (Cont.)
Android software Stack- Application Framework
 Enabling and simplifying the reuse of components
 Developers have full access to the same framework APIs
used by the core applications.
 Users are allowed to replace components.

13. 1328/04/2015 Android
System Architecture (Cont.)
Android software Stack- Libraries
 Including a set of C/C++ libraries used by components of
the Android system
 Exposed to developers through the Android application
framework

14. 1428/04/2015 Android
System Architecture (Cont.)
Android software Stack- Android Runtime
 Core Libraries
 Providing most of the functionality available in the
core libraries of the Java language
 APIs
 Data Structures
 Utilities
 File Access
 Network Access
 Graphics
 Etc

15. 1528/04/2015 Android
System Architecture (Cont.)
Android software Stack- Linux Kernel
 Relying on Linux Kernel 2.6 for core system services
 Memory and Process Management
 Network Stack
 Driver Model
 Security
 Providing an abstraction layer between the H/W and
the rest of the S/W stack

16. 1628/04/2015 Android
Developing Applications
Software development kit
 On 12 November 2007 the OHA released a preview of the Android
software development kit.
 Google is currently offering a cumulative of 10 million US dollars in
prize money for a competition rewarding developers of the most
innovative applications for the Android platform
 Several manufacturers have expressed interest in
implementing Google's Android software platform;
Samsung Electronics and LG Electronics will unveil
devices based on the platform by the end of 2008 in
the United States.

17. 1728/04/2015 Android
Developing Applications (Cont.)
Application Building Blocks
 Activity – user component interface, which corresponds to one
screen at a time
 Intent Reciever - wakes up the predefined action through the
external event
 Service – a task which is run on background
 Content Provider – a component, which allows sharing
some of the data with other processes and applications.

18. 1828/04/2015 Android
Comparison With Other OS
 Other then Android there are several other mobile
operating system which is used.
 Symbian, iOS, windows this are one of the most used
mobile operating systems.
