The document provides an overview of Android, a rapidly growing mobile application development platform based on a Linux kernel. It describes the Android architecture, which is divided into five sections across four main layers: Linux kernel, libraries, Android runtime, application framework, and applications. Additionally, it highlights Skillpractical as a resource for learning Android technology through various projects and community support.

1. Title: What everybody want to know about Android?
In recent times, the mobile application development is growing rapidly, in terms of both
revenues and in job scopes created by that field. In this i am explaining about brief summary
and overview of Android, the most emerging mobile application development platform
now-a-days.
Android Technology is an operating system which is based on a Linux kernel. It was designed
mainly for the touch screen mobile devices, such as smart phones and tablet computers,
with variants for television, cars and wrist wear.
Android Architecture Stack
We can consider Android OS as a software components which is divided into five sections
and in 4 main layers they are:
 Linux kernel
 Libraries
 Android runtime
 Application Framework
 Applications

2. Linux kernel:
Android uses the Linux kernel it supports wide range of hardware drivers. It is the heart of
the operating system that manages input and the output requests from software. It
provides the essential systemfunctionalities like process management, memory
management, device management like camera, keypad, display etc the kernel handles all
the items. It will not interact directly with the user but rather interacts with the shell and
other programs.
Libraries:
An Android library is structurally an equivalent as an Android app module. It can include
everything needed to create an app, including ASCII text file , resource files, and an
Android manifest. ... When you're building multiple apps that use a number of an
equivalent components, like activities, services, or UI layouts
Android Runtime:
Android Runtime is an application runtime environment employed by the Android OS . By
replacing the Dalvik method virtual machine originally employed by Android, ART performs
the interpretation of the application's bytecode into native instructions that are later
executed by the device's runtime environment.
Application Framework

3. The application frame work layer provides many higher level services to applications like
windows manager, view system, package manager, resource manager etc. the appliance
developers are allowed to form use of those services in their application.
Applications:
You will find all the android applications at the highest layer and you'll write your
application and install on this layer. Example of such applications are contacts, books,
browsers, services etc. Each application perform a special role within the over all
applications.
