what is android
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, since 2008.

features1. Application framework enabling reuse and replacement of
components2. Dalvik virtual machine optimized for mobile devices3. Integrated browser based on the open source WebKit engine4. Optimized graphics powered by a custom 2D graphics library;
3D graphics based on the OpenGL ES 1.0 specification (hardware acceleration optional)
5. SQLite for structured data storage6. Media support for common audio, video, and still image formats
(MPEG4, H.264, MP3, AAC, AMR, JPG, PNG, GIF)7. GSM Telephony (hardware dependent)8. Bluetooth, EDGE, 3G, and WiFi (hardware dependent)9. Camera, GPS, compass, and accelerometer (hardware
dependent)10. Rich development environment including a device emulator,
tools for debugging, memory and performance profiling, and a plugin for the Eclipse IDE
system architecture
others information
1. 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.
2. By providing an open development platform, Android offers developers the ability to build extremely rich and innovative applications. Developers are free to take advantage of the device hardware, access location information, run background services, set alarms, add notifications to the status bar, and much, much more.
3. 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 such as system C library, Media library, 3D library etc.
4. 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.
