I've been using menus successfully without much trouble, but I'm now finding it impossible to set up an ActionBar. The supposed solution, ActionBarSherlock does not support a .jar import and although I suppose it would be possible to use it through Eclipse, I really loathe Eclipse and would like to find a solution in the Processing IDE.  The Google documentation of its compatibility library and samples are abysmal.  I've been unable to get my SDK Manager to even download the samples.  The strategy I was attempting as to explore reflection and invoke methods that trigger the ActionBar that way, but it seems like a major headache.  I know that in theory Processing isn't suppose acknowledge the need for integrating a UI, but honestly, the development environment is tantalizingly close to being usable until you run into things like this that assume you are using Eclipse.  Arrgh!
