title: Custom menu to bookmark current url with Chrome custom tabs
body: <p>I'm trying out the new Chrome custom tabs and want to add a custom menu item to bookmark the displayed page url. I create a new pending intent to launch the bookmark activity but I cannot find a way to pass the current page url to the bookmark activity. Is this possible or not?</p>
  
  <p>This is how I create the menu item:</p>
  
  <pre><code>private void prepareMenuItems(CustomTabUiBuilder uiBuilder) {
      Intent menuIntent = new Intent();
      menuIntent.setClass(getApplicationContext(), this.getClass());
      Bundle menuBundle = ActivityOptions.makeCustomAnimation(this, android.R.anim.slide_in_left,
              android.R.anim.slide_out_right).toBundle();
      PendingIntent pi = PendingIntent.getActivity(getApplicationContext(), 0, menuIntent, 0,
              menuBundle);
      uiBuilder.addMenuItem("Bookmark page", pi);
      menuIntent.setClass(getApplicationContext(), BookmarkActivity.class);
  }
  </code></pre>
