PDK HTML Documentation

Looking for documentation and information about platform development we stumbeld across the Android PDK (Platform Development Kit) in the development directory of the Android source.

Thanks to the guide found at http://heejindev.wordpress.com/2009/06/18/how-to-build-android-pdk/ we were able to successfully build the html documentation.
To make the documentation work we needed to put the online-pdk directory (./out/target/common/docs/online-pdk/) under our Apache server root.

There is an online version of the PDK at
