title: Android Icon for "open" or "load"
body: <p>Is there a built-in Android icon for "open" or "load"?  I'm making menu items, and I see <code>ic_menu_save</code>, but there's no <code>ic_menu_open</code> nor <code>ic_menu_load</code>.  I guess I could just use <code>ic_menu_add</code>, but that's not quite right.  I;m looking for a little folder or something.  Surely others have needed an open icon?  </p>
