I really need to rebuild this app. I fixed a Force Close error caused when going into the Preamble and pressing defence. This takes the user to the Typos page. If the user swiped the screen it caused a NullPointerException. The simple fix was to check the contents of the HashTable being pulled. There is still an error (minor) when swiping left or right and the user is taken to the American DNA pages. This shouldn't happen but I am too tired to figure it out. Like I said it needs to be rebuilt.
