Fixed version (ground truth):

  TextView titleText=(TextView)infoText.findViewById(R.id.title);
  TextView descText=(TextView)infoText.findViewById(R.id.description);
  int selectedPosition=getArguments().getInt(ARG_SELECTED_IMAGE_POSITION);
  headerImage.setTransitionName(MainActivity.CAPTIONS[selectedPosition]);
  headerImage.setImageResource(MainActivity.IMAGES[selectedPosition]);
  titleText.setText(MainActivity.CAPTIONS[selectedPosition]);
  root.getViewTreeObserver().addOnPreDrawListener(new ViewTreeObserver.OnPreDrawListener(){
    @Override public boolean onPreDraw(){
      root.getViewTreeObserver().removeOnPreDrawListener(this);
      getActivity().startPostponedEnterTransition();
      return true;
    }
  }
);
  int imageResource=BACKGROUND_IMAGES[selectedPosition];
  Bitmap bitmap=BITMAP_CACHE.get(imageResource);
  if (BITMAP_CACHE.get(imageResource) == null) {
    backgroundImage.setImageResource(BACKGROUND_IMAGES[selectedPosition]);
    bitmap=(((BitmapDrawable)backgroundImage.getDrawable()).getBitmap());
    BITMAP_CACHE.put(imageResource,bitmap);
  }
 else {
    backgroundImage.setImageBitmap(bitmap);

  return root;
