I hope, trying to answer your question, I am not mistaken in accepting the following. If I please do the right thing.
I am not aware of any new updates to this drawables list on the site you linked to and personally, I have never seen such sites with a full list of drawables for new platforms.
However, if you are looking specifically for the new Android interface (I assume you mean ICS and above), you will find a decent list of drawables here: https://github.com/ChristopheVersieux/HoloEverywhere/tree/master/library/res However, this is not an exhaustive list.
This link refers to an Android library called Holo Everywhere .
As the saying goes, the best place to look for drawables for the latest platform is where you install your eclipse platforms. On my workstation, I can access the default resources (for a specific platform):
C: \ Program Files \ Android \ android-sdk \ platform \ android-16 \ data \ res
This has every resource used for the platform in question, and I find it very useful, especially during the topic. I can turn to XML and see how they are configured.
