title: Reference android.R.id.home on pre 3.0 devices
body: <p>Is there an easy way to get a reference to the home button on devices running less then 3.0?</p>
  
  <p>I can do findViewById(android.R.id.home) on 3.0 and later but that fails to work on older devices. I don't need to listen for clicks, I just need its location to position another view.</p>
