1SYSTEM MANAGEMENT | ANDROID OPERATING SYSTEM
Introduction
The Android was established by an organization, which is named as “ANDROID Inc.”
The Android Inc. is invented in Palo alto of California, U.S in 2003 whose originator was
“ANDY RUBIN”. However, the Android was then obtained by the Google in 2005 as well as
disclosed its broadcasting in 2007 with a development of OHA drove by Google [1]. Android
versatile working framework depends on the Linux part and is created by Google.
Explanation
The Android framework is a part of Linux operating system. It doesn't generally associate
with the clients and designers. However, the Linux Kernel consider to provide a level of
deliberation between the upper layers of the Android programming stack as well as the
equipment of devices [2]. Therefore, the Linux kernel version 2.6 is used to deliver a low-level
centre framework administration, for instants, low process, lower consumption of memory as
well as the power administration giving some gadget drivers for various equipment and network
support. The android application also provide some user entertainment features such as modern
display techniques, Wi-Fi connectivity as well as Dolby sound system and more [11]. In android
operating system java virtual machine is required to provide above mention features but java
source code does not support in android operating system, therefore Dalvik virtual machine is
developed to java support in android. However, it gives numerous larger amount administrations
to applications as Java classes. Therefore, android coder or programmers are permitted to make
utilization of these framework in their application development as well as for use [13]. This
system portrays the idea that Android applications are built from replaceable, compatible and

2SYSTEM MANAGEMENT | ANDROID OPERATING SYSTEM
reusable components. The Android system incorporates the accompanying with the following
important administrations:
Action Manager – The action manager or application manager is used to controls all parts
of the stack of an activity as well as application lifecycle [8].
Notices Manager – A notices manager or content provider publish and allow an
application to show notices to the client.
Resource Manager – The resource manager of the android operating system provides
access to non-code implanted resources, for example, UI designs, colour setting and string [6].
Location Manager – The location manager of any android device is utilized to track
geographical location of that device.
View System – The user interfaces are arranged by the view system as well as it
responsible to take input from the users [4].
Content Providers – this system is installed for find out which application is installed in
any android application as well as share information with different applications.
Communication Manager – The communication manager is the most usage service for
every android device for telephony service as well as gathering subscriber information.
Technical details
Presently, the majority of the application services are now available on the android
operating system that a user can perform on a computer are available on their cell phones also.
Which may contain important data and fetch form individual’s cell phones than past

infrastructure [4]. However, the android operating system provides more security to their users
by many authentication systems such as finger print scanner, pattern lock, sequence of numeric
password etc. Therefore, to perform such operations the android operating system must have
some software support as well as hardware support. However, they are updating their android
version for provide more flexible, light weight process, less consumption of memory etc.

An android application has used many libraries, but on the top most of the Linux kernel a
package of C and C++ libraries are utilized for developing android operating system and
upgrading the performance level. Here some of them are discussed and listed underneath [3].
System c library – a BSD– is library is embedded in to the Linux based device as well as
it utilized for implementation android system library.

4SYSTEM MANAGEMENT | ANDROID OPERATING SYSTEM
SQLite – SQLite database is used in the android operating system to save local data into
the ROM [12].
SSL - It is used to provide internet security.
SGL – the underlying 2D graphics engine.
Lib web core – a modern web browser engine which powers both the android browser as
well as an embedded web view [9].
OpenGL - The OpenGL/ES 3D graphics rendering API is used to provide java interface
support.
Media framework – The media framework is android application is used to decode binary
data into a video media format.
Web Kit – The web kit in android is utilized for display content in the browser.
SGL library – it is a 2D graphics engine that can help to provide graphical support for the
user interface in android application.
Media structure library - It is utilized to give various media extension which permit the
chronicle as well as playback of various media groups.
Web Kit library – is another most usable library in present days, which is being used to
rendering web contains on the system [2].
Lib web Core library – In present day web program engine which powers both the
android program as well as embedded web view.

SQLite library - is incorporates SQLite database administration classes in android
application as well as it uses for the sharing data by the receiver.
SSL library - It is utilized to give web security; this service or library provide the security
mechanism for secure connection [6].
OpenGL library – is responsible for utilizing to support the Java interface for illustrations
rendering API of OpenGL/ES 3D, which is applied for provide high quality graphics.
Advantages of Android OS
The advantages of the android operating system are followings:
The most common advantage is an android operating system is open to all users and
developer. The Linux is an open source OS so it can be modifying by anybody. The android
operating system (OS) can be treated as a multitasking OS. Android devised can run numerous
applications, it implies a user can access web while tuned on the music player [9]. The simplest
access to the Android App Market, which make it most attractive because of various gamming
application as well as computer based applications are also developed in android. A Google's
Android play store offers the users to download numerous applications for free. However, it also
supports flexible hardware device, where a user can change ROM. to customize a ROM in any
android device which does not harm this device as well as device.
There are many choices are assorted than apple IOS, however the IOS is restricted to the
iPhone from Apple. Where Android is available on various cell phones from different phone
manufacturer. For example, Samsung, Sony, Nokia, Motorola, HTC [5]. The Simplicity of
notification such as Email, the most recent articles from a RSS Reader as well as Email. There

6SYSTEM MANAGEMENT | ANDROID OPERATING SYSTEM
will dependably be a notice on the Home Screen of Android device. Therefore, no one will be
miss an important action on their device.
Disadvantages of Android OS
There is some disadvantage also assumed for android OS are listed below:
 Inefficient Battery – the Android device does not have efficient battery life than
some other devices. The working platform of the android is set to consume batter
power according to the application running to the device, which may drain battery
power [8].
 Promoting – The android application content few annoying promoting message.
Sometimes the application will generate advertisement for may e-commerce
based websites or news etc. which may be annoying for the users.
 Numerous applications contain infection - the infection embedded android
applications including Counter Strike Ground Force, and so forth. Android
Application contain infection likewise display in the Android Market [1].
Conclusion
This report defines android operating system structure and background study. Initially the
aim of this organization was to build up an operating system for innovative cameras. After
sometime they have understood that market for such cameras was not sufficiently. Therefore,
they have changing their goals that occupied their consideration regarding delivering a smart
phone operating system. The Android operating system has developed their own virtual machine
called DVM. This virtual machine is use to run Android applications which is already define in

this report. The Android OS framework is presently providing the best solution among the
various operating system of similar devises.
