Topic: -Google- Android

Description: Android is a software pack for mobile devices, these include a operating system, middleware and key applications. Additional programs can be written for these devices using the Java programming language.
Pulled from the official site for Android, Android includes:
  • 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
Libraries:
Android includes a set of C/C++ libraries used by various components of the Android system. These capabilities are exposed to developers through the Android application framework. Some of the core libraries are listed below:
  • System C library - a BSD-derived implementation of the standard C system library (libc), tuned for embedded Linux-based devices
  • Media Libraries - based on PacketVideo's OpenCORE; the libraries support playback and recording of many popular audio and video formats, as well as static image files, including MPEG4, H.264, MP3, AAC, AMR, JPG, and PNG
  • Surface Manager - manages access to the display subsystem and seamlessly composites 2D and 3D graphic layers from multiple applications
  • LibWebCore - a modern web browser engine which powers both the Android browser and an embeddable web view
  • SGL - the underlying 2D graphics engine
  • 3D libraries - an implementation based on OpenGL ES 1.0 APIs; the libraries use either hardware 3D acceleration (where available) or the included, highly optimized 3D software rasterizer
  • FreeType - bitmap and vector font rendering
  • SQLite - a powerful and lightweight relational database engine available to all applications
Applications:

Applications that Android's website talks about are:

Amazon Mp3 will be an application that will allow the users to download mp3's directly to their android system phone. Bonsai blast will be a game where one matches colored balls. Bread Crumbz will be an navigation application that uses pictures of outdoor and indoor locations to leave a visual "bread crumb" trail to one's destinations. Ecorio is an application that allows you to "track and reduce your carbon footprint."[6] PAC - MAN is classic game that will be offered with Android. ShopSavvy will be a shopping assistant program that will help the user find the best price for items by examining an item's barcode.

Terminology:

Middleware: A Computer software that connects software components or applications.
Dalvik virtual machine: A register-based virtual machine who was designed by Dan Bornstein. It is optimized for low memory requirements and is designed to allow multiple VM instances.
WebKit Engine : It's known to be the fastest rendering engine available.
SQLite: A software library that implements a self-contained, serverless, SQL databaase engine. This is the most widely deployed SQL database engine in the world. It's used in desktop computers as well as cellphones, PDAs, and MP3 players.
GSM: A trademark for an international wireless communication network for cellular phones.
Telephony: Telephone System, sytem of communication.
GSM Telephony: A built in hardware device.
EDGE: Enhanced Data Rates for Global Evolution. This is a backward-compatible digital mobile phone technology that allows improved data transmission rates. EDGE was initially by cingular, who is now AT&T.
3G: The third generation of wireless phones. It refers to pending improvements in wireless data and voice communications through any of a variety of proposed standards.
accelerometer: A device for measuring specific external force.
