Android is an open-source, Linux-based operating system primarily designed for touchscreen mobile devices. It was developed by Android Inc, which was later acquired by Google in 2005. Key points about Android include:
- It uses the Linux kernel as its core with additional software libraries for handling things like graphics, media playback, databases, and more.
- Applications run in a Java-like environment using the Dalvik virtual machine rather than a classic Java virtual machine.
- The software stack has seen many updates over the years through periodic version releases named after desserts or sweets.
Android 4.0 Ice Cream Sandwich aimed to unite the Android platforms for smartphones and tablets by bringing together the best features of Gingerbread and Honeycomb. It improved multitasking capabilities and merged the interfaces to provide a cohesive experience across all devices. The new version targeted a Q4 2011 release and was Google's most ambitious Android update to date, focused on creating a unified operating system for both phones and tablets.
Android is an open-source, Linux-based operating system designed primarily for touchscreen mobile devices. It is developed by Google and the Open Handset Alliance. The Android code is released under the Apache license as the Android Open Source Project. Key aspects of the Android architecture include the Linux kernel, native libraries, Dalvik virtual machine, application framework, and applications. Applications are written in Java and use Android components like activities, services, content providers, and broadcast receivers to perform functions. The Dalvik VM executes applications in a sandbox for security.

Difference between windows 7 and windows 8 and windows 8 featuresRizwan Ansari
Windows 8 represents a major departure from previous versions of Windows. It is based on the Metro design language, which facilitates a touchscreen user interface similar to mobile phones and tablets. Microsoft's Surface tablet, released in 2013, runs Windows 8. The version aims to work with both touchscreen and traditional keyboard-and-mouse systems. It has a tile-based screen with each tile representing a specific app. Users can access apps and switch between them by clicking or touching different areas of the screen.
The document discusses the key differences and features of Windows 8 and Windows 7. It covers topics such as operating system definition and goals, differences in start buttons, boot times, and memory management between the two systems. Hardware requirements and the benefits of Windows 7 like the start menu are compared to Windows 8's metro interface. Performance tests show Windows 8 has faster boot, shutdown, and file transfer speeds than Windows 7.

Acceleo - Let's start with an Android exampleJonathan Musset
--- Eclipse Con 2010 ---
Acceleo is a pragmatic implementation of the OMG* standard for code generation called MTL*. Still in incubation state, we plan to have Acceleo graduate for the next Eclipse simultaneous release (Helios).
Being an expert at code generation or Acceleo is not necessary to get started on your first code generator : using the Acceleo editor and the powerful features it exposes (completion, syntax highlighting, on-the-fly compilation, quick outline, ...), it is very easy to get started once you understand the most basic principles.
This talk presents both the MTL language and the Acceleo Development Toolkit which is provided in the M2T project. Beginners will learn what code generation, M2T, and Acceleo are, as well as how to use them on a concrete case-study. Acceleo addicts will discover the new standard syntax, new functionalities and techniques. We will give you enough of the basics to create your own code generation for a specific target system. We have chosen the Android platform as a target to show that we can also use Acceleo for mobile software.
Here is the talk agenda :
- Acceleo : What's that new code generation engine?
- Create an Android prototype and its corresponding model
- Initialize your code generation project from the prototype
- Editing your code generation file to make the Android prototype run
- Launching your code generation on another model example
- Packaging as an eclipse plug-in and for standalone usage
- Create new Android applications in few clicks
- How to override a specific behavior in the target environment
- On the developper side : How to make your own extensions with Acceleo?
We'll end the talk with other complex code generation examples made with Acceleo : EEF, UML to Java, Ecore to python, Migrating from a language to another...

This document provides an overview of the Android operating system, including its history, architecture, versions, features, advantages, and disadvantages. Android was founded in 2003 and was later acquired by Google in 2005. It uses an open source Linux kernel and is developed by the Open Handset Alliance. The architecture consists of four layers - the Linux kernel, native libraries, the Android runtime (Dalvik virtual machine), and applications. Key features include multi-tasking, a rich application ecosystem, and integration with Google services. Advantages are customization and openness, while disadvantages include inconsistent designs between apps and battery drain issues on some devices.
This document provides an overview of Android, including its history, versions, architecture, security features, advantages, and disadvantages. Android was founded in 2003 and is an open-source operating system based on the Linux kernel. It uses Java for application development and includes features like multi-touch interaction, accelerometers, and GPS. The Android architecture consists of applications, an application framework, native libraries and the Linux kernel. Security is enforced through process isolation and permissions. While Android provides customization, app availability and integration with Google services, disadvantages include inconsistent designs between apps, battery drain, and lack of control over third-party apps in the Android Market.

is
a
business

open
standards
applica5ons
for
mobile
devices.
6. • The
basic
layer
is
the
Linux
kernel.
The
whole
Android
OS
is
built
on
the
Linux
2.6
Kernel
.
•
It
is
contains
all
the
hardware
drivers.
Drivers
are
programs
that
control
and
communicate
with
the
hardware.
•
• The
Linux
kernel
also
acts
as
an
abstracCon
layer
between
the
hardware
and
other
soDware
layers.
• the
Linux
Kernel
manage
Memory
management,process
management,
networking,
security
seGngs
etc.
.
7. • The
next
layer
is
libraries.
It
is
this
layer
that
enables
the
device
to
handle
different
types
of
data.
These
libraries
are
wriJen
in
c
or
c++
language
.
• Surface
Manager:
It
is
used
for
composiCng
window
manager
with
off-‐screen
buffering.

you
cant
directly
draw
into
the
screen.your
drawings
go
to
the

8. • Dalvik
Virtual
Machine
• It
is
a
type
of
JVM
used
in
android
devices

processing
power
and
low
memory
environments.
Unlike
the
JVM,
the
Dvn
doesn’t
run
.class
files,
instead
it
runs
.dex
files.
.dex
files
are
built
from
.class
file
at
the
Cme
of
compilaCon
and
provides
higher
efficiency.
• The
Dalvik
VM
allows
created
mulCple
instance
simultaneously
providing
security,
isolaCon,
memory
management
and
threading
support.
It
is
developed
by
Dan

• Core
Java
Libraries
• These
are
different
from
Java
