-activity_number_output.xml now has two buttons instead of one. The styles were changed to mimic the layout of the buttons on activity_layout_input.xml. The Play Again button maintains its functionality while the addition of a Submit button will in the future launch a fragment which allows the player to submit there name and score into a database. This database will be displayed in the main menu of the application.
largestInt now is passed from NumberInput.java to NumberOutput.java. From here we've provided two fragments, one the default results which automatically displays upon creation, the second is a submission to the scoreboard which has not yet been programmed yet.

Key points, we've learned that we cannot simply transfer the data from one Activity straight to a Fragment which is being inflated by another Activity. The Bundle must be relayed through all involved components.

At least this finally is starting to work.
