2. INTRODUCTION HISTORY Architecture of ANDROID Versions Android 4.4 KITKAT UNIQUE FEATURES OF KITKAT DIFFERENCE B/w ANDROID & KITKAT COMPARISON WITH OTHER OssAPPLICATIONS 3. Android is an operating system designed primarily for touchscreen mobile devices such as smartphones and tablet computers, developed by Google in conjunction with the Open Handset Alliance.The Open Handset Alliance (OHA) is a consortium/association of 84 firms to develop open standards for mobile devices. Member firms include the following: 4. HISTORY: Founded by open handset alliance (OHA) by a group in 2003 by ANDY ROBIN,RICH MINER (co founder of wildfire communication) NICK SEARS (vpt-moblie) CHRIS WHITE(design and interface developed at web TV). ANDROID logo designed by California based graphic designer IRINA BLOCK. Google backed financially and latter brought in android in 2005. GOOGLE reveled in 2007 with first mobile android powered phone which was HTC DREAM was sold in October 22nd 2008. ANDROID is a open source and Google releases the code under Apache license. October 2012 approximately 700000 apps were available for downloads. 5. ArchitectureOf ANDROID 6. First layer in system architecture These include the applications shipped with android like the email client, SMS client, maps, browsers and also the applications developed and distributed through the Android market. 7. Second layer in system architecture These include the programs that manage the basic functions of the phone like resource allocation, voice call management, etc 8. The layer above to the Linux kernel is the Androids native libraries. These libraries are written in C/C++ languages. These libraries also run as processes within the underlying Linux kernel. The libraries are nothing but a set of instructions that tell the device how to handle different kinds of data (e.g. The media libraries support playing or recording various audio/video formats) 9. SQLite:This is a lightweight yet powerful relational database engine available for all applications to store data. Webkit:This is a browser engine providing tools for browsing web pages. Surface Manager: This is responsible for the graphics on the device screens OpenGL: Used to render 2D or 3D graphics to the screen 10. This is located on the same layer as the libraries layer. It consists of the core JAVA libraries and the Dalvik virtual machine. The core Java libraries are used for developing Android based applications. Dalvik VMs help in achieving the following: - better memory management -an application cannot interfere with other applications without permissions - threading support 11. The diagram below is a pictorial representation of the Android environment. It can be observed that each Android application runs under a separate virtual instance and each application has a unique user-id assigned to it. 12. This is last layer in system architecture Device drivers, power management, process management and networking services depend on the layer Android using Linux kernel 2.6 and android developed over time have been harmonized. Android is not exactly Linux. 13. The applications in Android can be mainly classified into two categories: -Android browser-based applications-Android-based applications (Android application package files .apk extension files) 14. We want to analyze files within the device,so how do we do this ?ADB (windows,linux,mac) 15. Android Debug Bridge (adb) command -Access a shell -Pull/push files -Many more 16. VERSIONS 17.

With Android operating system (OS) KitKat version 4.4 rolling out to mobile devices across the globe, Google is on to somethingAndroid is now more popular than iOS or the Windows phone. The OS tends to garner rave reviews for its ease of use and open source, but many iOS or Windows phone users argue that their preferred operating system can do just as much. In some respects thats true, but here are 10 features unique to Androids OS. 1) Near Field Communication (NFC) Most Android devices support NFC, which allows electronic devices to easily interact across short distances. The main aim here is to create a payment option that is simpler than carrying credit cards or cash, and while the market hasnt exploded as many experts had predicted, there may be an alternative in the works, in the form of Bluetooth Low Energy (BLE). 2) Alternate Keyboards Android supports multiple keyboards and makes them easy to install; the SwiftKey, Skype, and 8pen apps all offer ways to quickly change up your keyboard style. Other mobile operating systems either dont permit extra keyboards at all, or the process to install and use them are tedious and time-consuming. 3) Infrared Transmission The Android operating system supports a built-in infrared transmitter, allowing you to use your phone or tablet as a remote control. 4) No-Touch Control Using Android apps such as Wave Control, users can control their phones touch-free, using only gestures. Have messy hands but need to turn off your screen or change a song? Simple. This could prove especially useful if youre driving, so you can keep both eyes on the road. 23. 3D Android Glasses by SensicsAndroid Treadmill by Life Fitness Android LandlineVehicle GPS by PolaroidAndroid Navigation) Android CameraNavigation (Satellite MicrowaveInc.
