You have to give it a default value, in case the preference has not
yet been set by the user. That is the second parameter to getString()
("Value to return if this preference does not exist", per the
documentation):
http://developer.android.com/reference/android/content/SharedPreferences.html#getString(java.lang.String,
java.lang.String)

I repeat, you have to give it a default value, in case the preference
has not yet been set by the user.
> In the setup, I created this:

This should not be needed.
