The ppt with most basic android introduction (short and sweet) and atlast with app development demo...

1. A glimpse…

2. Overview
• Android, was founded in Palo Alto, California, United
States in October, 2003 by
Andy Rubin (co-founder of Danger),
Rich Miner (co-founder of Wildfire Communications),
Nick Sears (once VP at T-Mobile), and
Chris White (headed design and interface development
at WebTV) to develop, in Rubin's words
”smarter mobile devices that are more aware of its
owner's location and preferences"

3. Introduction
 Software platform from Google and the Open
Handset Alliance
 July 2005, Google acquired Android, Inc.
 November 2007, Open Handset Alliance formed
to develop open standards for mobile devices
 October 2008, Android available as open source
 December 2008, 14 new members joined Android
project

6. Android & Hardware
• Built-in Apps ≡ Apps created in SDK
• Leverage Linux kernel to interface with
hardware for better performance
• Open source platform promotes development
from global community

7. Features
 Reuse and replacement of components
 Dalvik virtual machine
 Integrated browser
 Optimized graphics
 SQLite
 Media support
 GSM Telephony
 Bluetooth, EDGE, 3G, and WiFi
 Camera, GPS, compass, and accelerometer
 Rich development environment

8. App fundamentals
• Apps are written in Java
• Bundled by Android Asset Packaging Tool
• Every App runs its own Linux process
• Each process has it’s own Java Virtual Machine
• Each App is assigned a unique Linux user ID
• Apps can share the same user ID to see each
other’s files

9. App components
Activity
◦ Present a visual user interface for one focused
endeavor the user can undertake
◦ Example: a list of menu items users can choose
from
Services
◦ Run in the background for an indefinite period of
time
◦ Example: calculate and provide the result to
activities that need it

10.  Broadcast Receivers
◦ Receive and react to broadcast announcements
◦ Example: announcements that the time zone has
changed
 Content Providers
◦ Store and retrieve data and make it accessible to all
applications
◦ Example: Android ships with a number of content
providers for common data types (e.g., audio, video,
images, personal contact information, etc.)
 Intents
◦ Hold the content of a message
◦ Example: convey a request for an activity to present an
image to the user or let the user edit some text
