Arduino ADK - 'AndroidAccesory' does not name a type

So I just got my Arduino ADK and as specified on theAccessory Development Kit 2011 Guide - http://developer.android.com/tools/adk/adk.html I was trying to open the Demokit sketch (firmware code), click File > Examples > AndroidAccessory > demokit. After Installing the ‘ADK software package’ library.

However the following error pop-up as I try to compile :0

’AndroidAccesory’ does not name a type

with the following log:
