Treehouse TeacherLooking into it!
Change this to public for now: private static final String KEY_USERENTRY = "KEY_USERENTRY";

42,478 PointsThat worked! Under normal circumstances that would be a private field right?

Treehouse TeacherYep, private is probably the better choice since our Bundle is specific to this Class. There could be situations where you'd want it to be public, and public wouldn't be an incorrect choice here either, but it's not a big deal either way.
