title: Return to last Activity
body: <p>In most Android apps, when you press the Home button to "minimize" the application and then open the application again, you will be taken to the screen you were last on in that Application.</p>
  
  <p>I've read the following:</p>
  
  <blockquote>
    <p>When launched via icon on the home
    screen, Android will always start the
    activity with the
    android.intent.action.MAIN filter in
    your AndroidManifest.xml, <strong>unless the
    application is already running (in
    which case it will obviously restore
    the activity on top of the stack).</strong></p>
  </blockquote>
  
  <p>but this is not happening.  When I launch the application a second time, it takes me to the main Activity.  The application isn't being terminated.  If I then navigate to the screen I was last on, all the data and such is there.</p>
  
  <p>How do I make it do what I want?  The related questions all seem to pose the same answer (the one I quoted above), but this is not holding true.</p>
