/**
 * AndroidX Transition Library provides Transition API back to API level 14.
 * <p>
 * Transition API allows you to animate various kinds of layout changes automatically. For example,
 * you can present a change of {@link android.view.View#setVisibility(int) visibility} as fade in /
 * out animation like below:
 * </p>
 * <pre>
 *     TextView message = findViewById(R.id.message);
 *     ViewGroup container = findViewById(R.id.container);
 *     Fade fade = new Fade();
 *
 *     TransitionManager.beginDelayedTransition(container, fade);
 *     message.setVisibility(View.INVISIBLE);
 * </pre>
 * @see <a href="https://developer.android.com/training/transitions">Transition API Guide</a>
