  • Presented By : Techno India College Of Technology, Srijib Roy
  • What is ANDROID • Google's Android is an open-source platform that's currently available on a wide variety of smart phones. • Android is a software stack for mobile devices that includes an operating system, middleware and key applications. • The Android SDK provides the tools and APIs necessary to begin developing applications on the Android platform using the Java programming language. • Based on the Linux kernel
  • Open Handset Alliace • Est. 5th Nov 2007, led by Google, open Source • Main Product Android Platform • Enthusiastic Support from Industry – Equipment makers – Network Operators • HTC was First to deliver ANDROID
  • Open Handset Alliance Members
  • Open Handset Alliance (OHA) → It's a consortium of several companies
  • ANDROID ARCHITECTURE The software stack is split into Four Layers:: • The application layer • The application framework • The libraries and runtime • The kernel
  • Applications Set of core applications including an email client, SMS program, calendar, maps, browser, contacts All applications are written using the Java programming language. Application Framework Access location information, run background services, set alarms, add notifications to the status bar, and much, much more. Build an application, including lists, grids, text boxes, buttons, and even an embeddable web browser Providing access to non-code resources such as localized strings, graphics, and layout files
  • Libraries • System C library - implementation of the C library (libc) • Media Libraries - based on PacketVideo's OpenCORE • Surface Manager - composites 2D and 3D graphic layers • LibWebCore - a modern embeddable web view • SGL - the underlying 2D graphics engine • 3D libraries - based on OpenGL ES 1.0 APIs; the libraries use hardware 3D acceleration • FreeType - bitmap and vector font rendering • SQLite - a powerful and lightweight relational database engine
  • • Android Runtime Includes a set of core libraries of JAVA that provides most of the functionality Runs in its own process, with its own instance of the Dalvik Virtual Machine The Dalvik VM executes files in the Dalvik Executable (.dex) Linux Kernel Acts as an abstraction layer between the hardware and the rest of the software stack. Relies on Linux version 2.6 for core system services such as security, memory management, process management, network stack, and driver model.
  • Features Dalvik virtual machine optimized for mobile devices Integrated browser based on the open source Web Kit engine 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 Wi-Fi (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 plug-in for the Eclipse IDE
  • Anatomy of Android Application There are four building blocks for an Android application: • Activity – a single screen • Intent Receiver – to execute in reaction to an external event(Phone Ring) • Service – code that is long-lived and runs without a UI(Media Player) • Content Provider – an application's data to be shared with other applications
  • WHY ANDROID?? • Layer This is a vote for the potential of Layer as much as the practical application. Walking around with your phone As Layer continues to add new layers, and as camera and mobile processing power continue to improve Layer can show you points of interest on a Google-type map
  • • AnyCut You can drop a lot of neat things on your Android home screen, but you can't quite get one-click access to everything in your phone's settings and extras You'll have access to the deepest guts of your settings, so switching 3G on and off, enabling location services, and other tricks are easy to pull off
  • • TasKiller Free Widgets you can add to your home screen for one-click system rescuing. Killing processes and apps willy-nilly can turn off alarms, kill background syncing, and have other unintended consequences.
  • • ASTRO File Manager ASTRO File Manager does a great job of letting you navigate files on your SD card and accessible internal memory, sure, but it also has its own built-in task killer, backs up applications, can send files as email attachments
  • • Slide Screen You use your Android Smartphone differently than your desktop computer Slide Screen replaces, or just augments, if you'd like, your phone's home screen, creating row after row of messages and feeds. Slide the center info bar up and down to look at more or less of your items, swipe to the right to dismiss items as read, and revel in having all your data on hand at once. Giving you 8 slots to put your most frequently accessed apps
  • Google’s Android OS for future MIDs • Google to utilize its Android-based operating system on future Moorestown • Android is available on a variety of handsets, including Google's Nexus One and Verizon's Motorola Droid • Two Android-centric phones — T-Mobile’s G1 and phone called “Magic” made by HTC • Google, the developer of Android, says there are eight or nine mobile phone manufacturers that are planning to release 18 to 20 Android-based models by the end of the year.
  • Cellphones Using Android OS hkc-pearl-pda-phone-wm6 Google-android-phone-prototype Samsung-galaxy-vs-htc-magic Sciphone_N19_Google with WIFI
  • Market Research • The Android OS has knocked Apple out of the number 2 slot and slid just behind RIM. • NPD says first quarter sales ::Android has 28% while Apple has 21%. • Not only are Android-powered devices now outselling iPhone but they’re also now besting BlackBerry, making Android the top selling mobile OS during the second quarter in the U.S. • NPD has the race at Android – 33%, RIM – 28%, and Apple – 22% for the period
  • iPhone OS 4 vs Android 2.2 vs Windows Phone 7 – The Inevitable Comparison
  • Conclusion • Android is open to all: industry, developers and users • Participating in many of the successful open source projects • Aims to be as easy to build for as the web. • Google Android is stepping into the next level of Mobile Internet
