The YouTube app for android has a sliding drawer. Is this a widget provided by the SDK? There seem to be a bunch of opensource ones, but they all behave in different ways. Is there an 'official' one provided by google?

There is a SlidingDrawer widget class, but it's deprecated (and I didn't understand the deprecation message):

Thanks
