I am trying to obtain the corresponding number from a single select setting on Android, and for some reason it tells me in the LogCat that "String cannot be cast to Integer at getInt. When I go in to analyze the value of the sharedPref at the time of mEventLanguageSelection assignment. At that point, it says KEY_LANGUAGE_SELECTION_LIST=2, which I am quite certain means that getInt should return a value of 2. What is happening?

The 'android:key' is a String Preference and not an integer. Hence you should be using sharedPref.getString("KEY_LANGUAGE_SELECTION_LIST", ""); and not getInt
From the docs
Must be a string value, using '\;' to escape characters such as '\n' or '\uxxxx' for a unicode character.
