##Installing the Windows development environment
============================================================================================

#Download and install the Android SDK from here: http://developer.android.com/sdk/index.html 
You should download and install the ADT Bundle for Windows(of course you can DIY). This will give you a .zip file. There is no executable installer.  
You will just have to unzip this into a directory.  For this example I unziped this file into D:\Android-sdk.

#Then the NDK http://developer.android.com/tools/sdk/ndk/index.html

#Need to get Java JDK as well
