If you are having trouble seeing the animation, consider making the `CheatActivity` use a custom background color

When working through the animation code in Ch7 it can be hard to distinguish the white on white transition. To help I made the cheat activity’s background orange via android:background="@android:color/holo_orange_dark" on the root LinearLayout.

Also note, the custom animation we are setting and the default one are very similar so don’t expect anything too drastic.
