+   * In Setup Wizard, all Just-a-sec style screens (i.e. screens that has an indeterminate
+   * progress bar and automatically finishes itself), should do a cross-fade when entering or
+   * exiting the screen. For all other screens, the transition should be a slide-in-from-right
+   * or customized.
+   *
+   * We use two different ways to override the transitions. The first is calling
+   * overridePendingTransition in code, and the second is using windowAnimationStyle in the theme.
+   * They have the following priority when framework is figuring out what transition to use:
+   * 1. overridePendingTransition, entering activity (highest priority)
+   * 2. overridePendingTransition, exiting activity
+   * 3. windowAnimationStyle, entering activity
+   * 4. windowAnimationStyle, exiting activity
+   *
+   * This is why, in general, overridePendingTransition is used to specify the fade animation,
+   * while windowAnimationStyle is used to specify the slide transition. This way fade animation
+   * will take priority over the slide animation.
+   *
+   * Below are types of animation when switching activities. These are return values for
+   * {@link #getTransition()}. Each of these values represents 4 animations: (backward exit,
+   * backward enter, forward exit, forward enter).

+   * We override the transition in the following flow

+   * |              | going forward           | going backward           |
