Java – Convert button is not shown in the demo

I’m running a demo from https://github.com/googlecast/CastVideos-android .

It depends on the library located here https://github.com/googlecast/CastCompanionLibrary-android

The project sets up all the necessary libraries and required jars.

The project compiles and runs without problems, except that the chromecast button does not appear in the actionBar.

If I modify onCreate with the following, the button appears:

mSelector = new MediaRouteSelector.Builder()
      .addControlCategory(MediaControlIntent.CATEGORY_LIVE_AUDIO)
      .addControlCategory(MediaControlIntent.CATEGORY_LIVE_VIDEO)
      .addControlCategory(MediaControlIntent.CATEGORY_REMOTE_PLAYBACK)
      .addControlCategory(CastMediaControlIntent.categoryForCast(getResources().getString(R.string.app_id))).build();

and modify onCreateOptionsMenu :

 @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        super.onCreateOptionsMenu(menu);
        getMenuInflater().inflate(R.menu.main, menu);

mediaRouteMenuItem = mCastManager.addMediaRouterButton(menu, R.id.media_route_menu_item);
      Attach the MediaRouteSelector to the menu item

MenuItem 
        mediaRouteMenuItem = menu.findItem(R.id.media_route_menu_item);
        MediaRouteActionProvider mediaRouteActionProvider = (MediaRouteActionProvider)MenuItemCompat.getActionProvider(mediaRouteMenuItem);
        mediaRouteActionProvider.setRouteSelector(mSelector);
        return true;
    }

If I simply keep onCreateOptionsMenu out of the box, then it doesn’t work.

@Override
    public boolean onCreateOptionsMenu(Menu menu) {
        super.onCreateOptionsMenu(menu);
        getMenuInflater().inflate(R.menu.main, menu);

mediaRouteMenuItem = mCastManager.addMediaRouterButton(menu, R.id.media_route_menu_item);        
        return true;
    }

Any thoughts on why this is?
