Overview
ABSTRACT
The Android platform is an operating system dedicated to the development of applications for mobile-phones, PDAs, tablets and other home automation devices. Android applications naturally integrate Google services, Google Maps, Google Talk, Gmail, Google Agenda and YouTube. APIs dedicated to the management of multiple sensors are available. Android has specific and fundamental concepts. The original notion of "intent" introduces the possibility of a dynamic binding between components from different applications. Android also offers persistence and internal or external data sharing mechanisms.

INTRODUCTION
Android is an open source (free software) operating system based on a Linux kernel version 2.6 (device, memory and process management) aimed at developing applications for mobiles, PDAs (Personal Digital Assistants), tablets and other home automation devices.
The Android executive includes a virtual machine (Dalvik VM) and a set of C/C++ libraries used by the various system components. The libraries cover telephony, multimedia, 2D and 3D graphics, user interfaces (UI) and connectivity (HTTP, Bluetooth, Wi-Fi, EDGE, 3G, GSM).
Android integrates Google services, Google Maps, Google Talk, Gmail, Google Calendar, YouTube, geolocation and sensor management (accelerometer, gyroscope, atmospheric pressure, temperature, light, magnetic field, proximity, near-field communication).
Historically, several versions of Android have been released since 2009: V1.5 (Cupcake April 2009), V1.6 (Donut Sept 2009), V 2.1 (Eclair Oct 2009), V 2.2 (Froyo May 2010), V2.3 (Gingerbread Nov 2010), V 3.0 (Honeycomb Feb 2011), V 4.0 (Ice Cream Sandwich). With version 2.0, Android introduces multi-touch, advanced search capabilities and text-to-speech, as well as the possibility of using HTML 5.
The Android framework enables components to be managed and reused. It offers a set of services for presenting views on the screen, accessing and sharing data between applications, managing resources and alerts, and managing the lifecycle of different activities.
