    Android OS Android OS Presentation Transcript

    • ANDROID A GOOGLE OS BY RIZWAN M H
    •  INTRODUCTION  ORGIN OF ANDROID  PLATFORM  SOFTWARE DEVELOPMENT  VERSIONS OF ANDROID  LIMITATIONS  FURURE OF ANDROID  APPLICATION DEVELOPMENT
    • INTRODUCTION
    •  Android is a software cluster for mobile devices that includes an operating system OS, key applications and middleware.  About the design, Kernel of Android is based on Linux kernel further furnished by Google.  Android doesn’t have a essential X Windows System nor does it support the full set of standard GNU libraries, which makes it difficult to port existing Linux applications or libraries to Android. Applications Kernel CPU Memory Devices
    • Origin OF ANDROID .
    •  Android was founded in Palo Alto, California in October 2003 by Andy Rubin, Rich Miner, Nick Sears and Chris White who work at “Google” to develop. “…smarter mobile devices that are more aware of its owner’s location and preferences.”
    •  Android was bought by “Google” in 2005.  On the 5th of the November 2007 the Open Handset Alliance, a consortium of several companies was unveiled with the goal to develop open standards for mobile services.
    • PLATFORM
    •  HARDWARE  Android is not a single piece of hardware; it’s a complete, end-toend software platform that can be adapted to work on any number of hardware configurations.  Everything is there, from the boot loader all the way up to the applications
    •  OPERATING SYSTEM  Android uses Linux for its device drivers, memory management, process management and networking.  The next level contains Android native libraries. They are all written in C/C++ internally, but calling through Java interfaces,  In this layer, Surface Manager, 2D and 3D graphics, Media Codecs, the SQL database (SQLite) and a web browser engine (WebKit).
    •  NETWORK CONNECTIVITY It supports wireless communications using :  GSM mobile-phone technology  3G technology  802.11 Wi-Fi networks
    • SECURITY  Android is a multi-process system, in which each application (and parts of the system) runs in its own process.  Most security between applications and the system is enforced at the process level through standard Linux facilities, such as user and group IDs that are assigned to applications.
    •  FUTURE POSSIBILITIES The OHA is committed to make their vision a reality: to deploy the Android platform for every mobile operator, handset manufacturers and developers to build innovative devices  Intel doesn’t want to lose ownership of the netbook market, so they need to prepare for anything, including Android  More Android devices are coming and some will push the envelope even further
    • Software development
    •  DEVELOPMENT REQUIREMENTS  JAVA  Android SDK  Eclipse IDE (or ) MonoDevelop (Xamarin)  PROGRAMMING LANGUAGES  JAVA – officially supported.
    • Android versions
    •  Android 1.0, the first commercial version of the software, was released on September 23, 2008.  HTC dream first commercially sold out mobile which runs on android on Oct 22 2008.  On February 9, 2009, Android 1.1 update was released, initially for the HTC Dream only.  Android 1.1 was known as "Petit Four" but not used officially.
    •  On April 30, 2009, the Android 1.5 update was released, based on Linux kernel 2.6.27. This was the first release to officially use a name based on a dessert ("Cupcake")

    •  On February 22, 2011, the Android 3.0 (Honeycomb) SDK – the first tablet-only Android update – was released, based on Linux kernel 2.6.36. The first device featuring this version, the Motorola Xoom tablet, was released on February 24, 2011.
    •  The SDK for Android 4.0.1 (Ice Cream Sandwich), based on Linux kernel 3.0.1, was publicly released on October 19, 2011.Googles Gabe Cohen stated that Android 4.0 was "theoretically compatible" with any Android 2.3.x device in production at that time.
    •  On June 27, 2012, at the Google I/O conference, Google announced Android 4.1 (Jelly Bean). Based on Linux kernel 3.0.31, Jelly Bean was an incremental update with the primary aim of improving the functionality and performance of the user interface. Nexus 7 the first device to run Jelly Bean.
