25. What is Android?
• Android delivers a complete set of software for
mobile devices
Operating System
Middleware
Key mobile applications
:Open

• Fast & Easy Application Development

26. History of Android
• The history of Android begins in October 2003 — well before
the term smartphone was widely used and several years
before Apple announced its first iPhone and iOS.
• Android Inc was founded in Palo Alto, California. Its four
founders were Rich Miner, Nick Sears, Chris White, and Andy
Rubin.

27. •Google bought Android in 2005 and everything
changed.

28. • In 2005, the next big chapter in Android’s history began
when the original company was acquired by Google. Rubin
and other founding members stayed on to continue
developing the OS under their new owners.

29. Android Logo

30. Cont.
• The now-familiar logo for the Android OS, which looks like a
combination of a robot and a green bug, was created by
Irina Blok while she was employed by Google. Blok has said
that the only directive she was given by the design team at
Google was to make the logo look like a robot.

39. Android Architecture

40. Linux Kernel
• Android OS is built on top of the Linux 2.6 Kernel
– Linux Core functionality
• Memory management
• Process management
• Networking
• Security settings
– Hardware drivers
l

41. Libraries
• Android’s native libraries.
– Libc: c standard lib.
– SSL: Secure Socket Layer
– SGL ( Scalable Graphic Library): 2D
image engine
– OpenGL|ES: 3D image engine /API
– Media Framework: media codecs
– SQLite: Database engine
– WebKit: Kernel of web browser
– FreeType: Bitmap and Vector
– SufraceManager: Compose window
manager with off-screen buffering.

42. Android Runtime
• Core Libraries
– Provides the functionality of the JAVA
Programming Language
• Dalvik VM
– A type of Java Virtual Machine
– Register based (not stack machine
like JVM)
– Optimization for low memory
requirements
Each Android application:
• runs on its own Process
• runs on its own Instance of Dalvik VM
• is assigned its own Linux user ID

43. Application Framework
• The blocks that our applications directly interact with.
• Important blocks:
– Activity Manager: Manages the activity life cycle of applications
– Content Providers: Manage the data sharing between
applications
– Telephony Manager: Manages all voice calls. We use
telephony manager if we want to access voice calls in our
application.
– Location Manager: Location management, using GPS or cell
tower
– Resource Manager: Manage the various types of resources we
use in our Application

44. Application Framework

45. Applications
This is where our applications are placed.
Some pre-installed applications:
– SMS client app
– Dialer
– Web browser
– Contact manager
• As developers, we are able to write an app
which replaces any existing system app.
• No compulsory applications
• Equality among apps
• Easily embedded web browser
• Parallel running

46. App Development in Android
Design applications for a variety of devices
Build anything from 3D games to social networks
Use a diverse set of information in your apps including location,
movement, touch interactions, images, sounds, and much more
Release an preview version of your application to a select group of users
Deploy your applications to the Google play store and make it available
to millions of users
Collect actual user data to upgrade and add new features to your
application

47. Android SDK
SDK – Software Development Kit Provides tools to create, develop,
debug, analyze and enhance Android applications including:
. Android emulators – to test your software on a simulation of a wide
range of configurations, screen sizes, and resolutions.
Debugging tools – to help you find the issues in your applications and
fix them as quickly as possible.

48. Android SDK
Analyzing and Optimizing tools – so that once you build your
application you can optimize it to reach its full potential in speed and
performance.
Code Samples: There is also lots of documentation and actual Android
source code available in the Android SDK so you can learn from the
actual developers of Android about naming conventions and code
syntax.

49. Android Studio
Based on JetBrains IntelliJ IDEA software
Designed specifically for Android development
Currently offers features including
WYSIWYG Editor with real-time app rendering
Gradle-based build support
Lint tools to catch performance, usability, version compatibility and
other problems
Template-based wizards to create common Android designs and
components
ProGuard and app-signing capabilities
Now the official Android IDE (integrated development environment)
