48    * In Setup Wizard, all Just-a-sec style screens (i.e. screens that has an indeterminate
49    * progress bar and automatically finishes itself), should do a cross-fade when entering or
50    * exiting the screen. For all other screens, the transition should be a slide-in-from-right
51    * or customized.
52    *
53    * We use two different ways to override the transitions. The first is calling
54    * overridePendingTransition in code, and the second is using windowAnimationStyle in the theme.
55    * They have the following priority when framework is figuring out what transition to use:
56    * 1. overridePendingTransition, entering activity (highest priority)
57    * 2. overridePendingTransition, exiting activity
58    * 3. windowAnimationStyle, entering activity
59    * 4. windowAnimationStyle, exiting activity
60    *
61    * This is why, in general, overridePendingTransition is used to specify the fade animation,
62    * while windowAnimationStyle is used to specify the slide transition. This way fade animation
63    * will take priority over the slide animation.
64    *
65    * Below are types of animation when switching activities. These are return values for
66    * {@link #getTransition()}. Each of these values represents 4 animations: (backward exit,
67    * backward enter, forward exit, forward enter).
68    *
69    * We override the transition in the following flow
70    * +--------------+-------------------------+--------------------------+
71    * |              | going forward           | going backward           |
72    * +--------------+-------------------------+--------------------------+
73    * | old activity | startActivity(OnResult) | onActivityResult         |
74    * +--------------+-------------------------+--------------------------+
75    * | new activity | onStart                 | finish (RESULT_CANCELED) |
