title: Hide Activity without finish()
body: <p>I want my application to launch another activity/application (in this case, the Browser application), but currently when the user presses the Back button to exit the Browser, they return back to my Activity.</p>
  
  <p>How can I make it so they do not come back to my activity after leaving the Browser, <strong>but</strong> if they relaunch my application later, the <code>Activity</code> stack of my application is as it was previously (i.e., cannot <code>finish()</code>, because that will remove the current <code>Activity</code> from the stack)?</p>
