title: Snackbar behind navigation bar
body: <p>In landscape mode, I am using</p>
  
  <pre><code>    window.getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION);
  window.getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN | View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION| View.SYSTEM_UI_FLAG_LAYOUT_STABLE);
  </code></pre>
  
  <p>to show and hide navigation bar.</p>
  
  <p>When I create Snackbar while navigation is showing</p>
  
  <pre><code>Snackbar bar  = Snackbar.make(snackbarContainer, "exiting", Snackbar.LENGTH_INDEFINITE);
      bar.setAction("Testing", new View.OnClickListener() {
          @Override
          public void onClick(View v) {
              //no-op
          }
      });
      bar.show();
  </code></pre>
  
  <p>The Snackbar's action text is being covered by the navigation bar.
  Is there a way to adjust snackbar's width automatically based on whether the navigation bar is showing or not?</p>
