System Architecture (Cont.)

Android software Stack

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.

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.

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

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

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

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.

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.

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.

Sales Comparison Of OS

2028/04/2015 Android

Advantages & Disadvantages

It is open source operating system. All applications are treated equal. It will be more secure than Iphone OS. Android based products will be cheaper than its proprietary

competitors.

Advantage

DisadvantagesAndroid applications must be written in Java.Android has no (obvious) standards strategy or upgrade path.

Conclusion And Future scope

Android is now stepping up in next level of mobile internet.

There are chances of Android Mobile sales becomes more then iPhone in next two years.

Google may launch another version of android that starts M because Google is launching all the android versions in the alphabetical order.

There are chances of Android may become the widely used operating system in world.
