What is the directory structure of android AOSP root tree?

This is short version of what you will find when you download the Android source. I will leave out some minor directories and dig deeper into a couple of the important ones. Basically what you will get (based on the (Kit Kat - 4.4.4), in alphabetical order: Bionic- the C-runtime for Android. Note that Android is not using glibc like most Linux distributions. Instead the c-library is called bionic and is based mostly on BSD-derived sources. In this folder you will find the source for the c-library, math and other core runtime libraries.Bootable- boot and startup related code. Some of it is legacy, the fastboot protocol info could be interesting since it is implemented by boot loaders in a number of devices such as the Nexus ones.Build- the build system implementation including all the core make file templates.

Nexus S looks like a state of the art - good starting point if one wants to get past the monotonic Nokia's piece of the cake. I just want to share with you my experience on reading a MiFare Classic tag using the Nexus S..and the Android platform. 

You need to have:
A MiFare Classic 1k Tag - ( hopefully you know the keys for its Blocks :=) )
Android SDK and IDE

Some Basics about the card:
MiFare classic cards store data in its Sectors. In MiFare classic 1k card there are 16 of them. Each Sector contains 4 blocks.  You can store 16 bytes in each block.
