What is Android?

Android is a mobile phone operating system developed by Google. Android is unique because Google is actively developing the platform but giving it away for free to hardware manufacturers and phone carriers who want to use Android on their devices.

Features

* 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 graphicsbased on the OpenGL ES 1.0 specification (hardware accelerationoptional)* 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 fordebugging, memory and performance profiling, and a plugin for the Eclipse IDE

Android Architecture


Applications

Android will ship with a set of core applications including an email client, SMS program, calendar, maps, browser, contacts, and others. All applications are written using the Java programming language.

Application Framework

Developers have full access to the same framework APIs used by the core applications. The application architecture is designed to simplify the reuse of components; any application can publish its capabilities and any other application may then make use of those capabilities (subject to security constraints enforced by the framework). This same mechanism allows components to be replaced by the user.


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.

Android Runtime

Android includes a set of core libraries that provides most of the functionality available in the core libraries of the Java programming language.

Linux Kernel

Android relies on Linux version 2.6 for core system services such as security, memory management, process management, network stack, and driver model. The kernel also acts as an abstraction layer between the hardware and the rest of the software stack.
