Android is a mobile operating system developed by Google, with its versions named in alphabetical order after food items. Built on a Linux kernel, it features an application framework, native libraries, and supports a variety of devices and applications. The document outlines the architecture of Android, its updates, and compares it with Microsoft's operating system, including features like touch technology and application support.

6.  ANDROID is a word in itself. It does not have
any full form. It is a mobile operating system
designed and developed by Google.

7.  Android 1.0 ALPHA
 Android 1.1 BETA
 Android 1.5 CUPCAKE

8.  Android 1.6 DONUT
 Android 2.0/2.1 ÉCLAIR
 Android 2.2 FROYO

9.  Android 2.3 GINGER BREAD
 Android 3.0/3.1/3.2 HONEYCOMB
 Android 4.0 ICE CREAM SANDWICH

10.  Android 4.1 JELLY BEAN
 Android 4.4 KIT KAT
 Android 5.0 LOLLIPOP

11.  We have noticed that all the versions of
android is in alphabetical order…….
See this

12.  The latest update which is released
i.e. Lollypop
 Hence the next android version is going to be a food
name starting with M but surely except Mango cause
Mango is an OS of Microsoft. It could be anything
Maggi
Mayonese
Momos,anything

14.  The basic layer is the Linux kernel. The whole
Android OS is built on top of the Linux 2.6
Kernel with some further architectural
changes made by Google. It is this Linux that
interacts with the hardware and contains all
the essential hardware drivers. Drivers are
programs that control and communicate
with the hardware.

15.  Applications are the top layer in the Android
architecture and this is where our
applications are goanna fit. Several standard
applications comes pre-installed with every
device, such as:
 SMS client app
 Phone
 Web browser
 Contact manager etc…….

16.  These are the blocks that our applications
directly interacts with. These programs manage
the basic functions of phone like resource
management, voice call management etc. As a
developer, you just consider these are some
basic tools with which we are building our
applications.
 Important blocks of Application framework are:
Activity Manager
 Content Providers
 Telephony Manager etc…….

17.  The next layer is the Android’s native libraries. It is
this layer that enables the device to handle different
types of data. These libraries are written in c or c++
language and are specific for a particular hardware.
 Some of the important native libraries include the
following:
Surface Manager
Media framework
SQLite etc…..

18.  Android Runtime consists of Dalvik Virtual
machine and Core Java libraries.
 Dalvik Virtual Machine
 Core Java Libraries
