title: Get index of selected tab in tabHost
body: <p>I'm trying to store the index of the currently selected tab in onSaveInstanceState so I can restore it. However the getCurrentTab apparantely gives me back the String I used in the etTabHost().newTabSpec, which I find a bit weird since the documentation says it returns an int and setCurrentTab also taking an int.
  Does anyone know how I can get the index of my currently selected tab so I can restore it?</p>
