looks like your project configuration is incorrect. The library must be marked as a library project in order for the resources to be generated. If you look in
yt-london-hackathon-sample-code/youtube-player-api-codelab/YouTube Player API Codelab directory in the
tarball we shared, you will find the
1416.pdf codelab instructions presentation. Page 11 has the instructions you need.
