• Add and EditTextPreference with all of the appropriate strings stored in strings.xml. It should have a key, default value of 1 and title.
• Modify the setupSharedPreferences method and onSharedPreferencesChanged method to properly update the minSizeScale, assuming a proper numerical value is saved in shared preferences.
• Add code here to properly set the summary for an EditTextPreference.
