title: Restoring original activity as it is (like home button) when back button pressed
body: <p>I am designing android application using tabHost. </p>
  
  <p>TabActivity is always being launched from anther activity( suppose, Activity A). After that Activity A has no use. </p>
  
  <p>When I am on tabActivity &amp; if back button is pressed, then all goes in background( like every app). Now using task manager when I start app again, I want to retain tabActivity as it was. (like home button.) But currently I am getting Activity A. (as with back Button activities are getting destroyed.)</p>
  
  <p>In short, I want to override backButton similar to Home Button.</p>
  
  <p>I tried without luck with moveTaskToBack(true). </p>
  
  <p>Can anybody suggest solution?</p>
