3. WHAT IS ANDROID?
 Android is a software stack for mobile devices that
includes an operating system, middleware and key
applications.
 Android is an operating system based on Linux and Java
Open Source. It is a robot or artificial organism.

4. HISTORY OF ANDROID
 Android, Inc. was founded in California
in October 2003 by Andy Rubin.
 Google acquired Android Inc.
on August 17, 2005.
 The first commercially available phone
to run Android was the HTC Dream,
released on October 22, 2008.

5. VERSIONS OF ANDROID

6. FEATURES OF ANDROID
Some of its features are as follows:
 Application framework enabling reuse and replacement of
components
 Dalvik virtual machine optimized for mobile devices
 Integrated browser based on the open source WebKit engine
 Optimized graphics powered by a custom 2D graphics library; 3D
graphics based on the OpenGL ES 1.0 specification (hardware
acceleration optional)
 SQLite for structured data storage
 Media support for common audio, video, and still image formats
(MPEG4, H.264, MP3, AAC, AMR, JPG, PNG, GIF)
 GSM Telephony (hardware dependent)
 Bluetooth, EDGE, 3G, and WiFi (hardware dependent)
 Camera, GPS, compass, and accelerometer (hardware dependent)
 Rich development environment including a device emulator, tools
for debugging, memory and performance profiling, and a plugin for
the Eclipse IDE

7. ARCHITECTURE OF ANDROID

8. ADVANTAGES OF ANDROID PLATFORM

accessibility to a rich development environment.
 Android facilitates swift information gathering and
provides accurate information.

11. TECHNICAL ASPECTS OF ANDROID APPS
DEVELOPMENT
 Android applications can developed by using Java
programming
 Android uses CDMA, GSM, Wi-Fi, EDGE, EV-
DO, Bluetooth and UMTS to receive and send data on
different platforms.
 3D as well as 2D graphics can be utilized.

12. USE OF SDK IN ANDROID APP
DEVELOPMENT
 Android SDK tool contains tools for debugging and
testing your application and other utility tools.
