Linux Kernel 2.6

Abstraction layer between the hardware and software stack

Why Linux? - Proven driver model and has existing drivers. - Has memory management, security management, networking, core operating system infrastructure, etc. - Robust and already has been proven over time. Linux Kernel :Android ArchitectureSource: http://en.wikipedia.org/wiki/Android_operating_system

Libraries :Android ArchitectureThe next level up is the native libraries. Everything that you see here in green is written in C and C++.Source: http://en.wikipedia.org/wiki/Android_operating_system

Android Runtime :Android ArchitectureMain Component: Dalvik Virtual Machine -Optimized for running in an embedded environment (limited- memory, CPU,battery)? Source: http://en.wikipedia.org/wiki/Android_operating_system

Application Framework:Android ArchitectureThis is all written in a Java programming language and the application framework is the toolkit that all applications use.

These applications include the ones that come with a phone like the home applications, or the phone application.

It includes applications written by Google, and it includes apps that will be written by you. So, all apps use the same framework and the same APIs.Source: http://en.wikipedia.org/wiki/Android_operating_system

Architecture

Applications:Android ArchitectureAnd the final layer on top is Applications.

This is where all the applications get written. It includes the home application, the contacts application, the browser, and your apps.

And everything at this layer is, again, using the same app framework provided by the layers below.Source: http://en.wikipedia.org/wiki/Android_operating_system
