title: How to display 2 fragments side by side in landscape
body: <p>I have an Activity1 hosting <code>ListFragmentA</code>.<br>
  On clicking an item of the list I launch Activity2 hosting <code>ListFragmentB</code>.<br>
  Both in portrait and landscape I see 1 list at a time.<br>
  I am interested when I am in landscape mode (or in a tablet I guess for that matter) to see both fragments.<br>
  I.e. the <code>ListFragmentA</code> in the left side of the display and the <code>ListFragmentB</code> in the right. So that when the user presses an item from <code>ListFragmentA</code> the correct data in <code>ListFragmentB</code> are displayed.<br>
  How is this done? Via layouts in landscape mode seems to me tedious/wrong and not sure how it is done to be honest.<br>
  Is there a good example I could look into?</p>
