title: Swipe between Android activities as with ViewPager
body: <p>In my Android application I have two separate but related top-level screens / activities. I want to have two separate launcher icons for them, but allow the user to "swipe" between them, as with ViewPager.</p>
  
  <p>The options I see are:</p>
  
  <ol>
  <li><p>Implement two separate activities, and somehow allow swiping between them. The issues is that ViewPager can't be used with two separate activities.</p></li>
  <li><p>Implement a single activity with two fragments, and use the ViewPager to switch between them. The swiping is simple, but is it possible to have two launchers that automatically switch to the correct fragment?</p></li>
  </ol>
  
  <p>Is any of the above two options feasible, or is there something else I can try?</p>
