Linux Kernel :
Android Architecture

 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.

Libraries :

The next level up is the native libraries. Everything
that you see here in green is written in C and C++.

16

Android Runtime :

Main Component: Dalvik Virtual Machine
-Optimized for running in an embedded environment (limitedmemory, CPU,battery)?

Application Framework:

This 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.

Applications:

And 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.

Software Development :
