Default bindPreferenceSummaryToValue crashes for non-string types

Question

I\'m following the example method to add a compatible preference/ fragment dialog found here. When doing so, I have found that if I have preferences that are Integers, Boolean,

There isn't a clean solution that I can find, but the best workaround seems to be something like this, using instanceof to figure out what type of data you are dealing with.

private static void bindPreferenceSummaryToValue(Preference preference) {
    // Set the listener to watch for value changes.
    preference
            .setOnPreferenceChangeListener(sBindPreferenceSummaryToValueListener);


    if (preference instanceof SeekBarPreference)
    {
        // Trigger the listener immediately with the preference's
        // current value.
        sBindPreferenceSummaryToValueListener.onPreferenceChange(
                preference,
                PreferenceManager.getDefaultSharedPreferences(
                        preference.getContext()).getInt(preference.getKey(),0));
    }
    else if (preference instanceof CheckBoxPreference)
    {
        // Trigger the listener immediately with the preference's
        // current value.
        sBindPreferenceSummaryToValueListener.onPreferenceChange(
                preference,
                PreferenceManager.getDefaultSharedPreferences(
                        preference.getContext()).getBoolean(preference.getKey(),true));
    }
}

private static void bindPreferenceSummaryToValue(Preference preference) {
//Todo
}

this method is used for showing the current value of your preference, e.g If you'r using <SwitchPreference/> which has value as true or false it will display that value in summary. You do not need to show boolean values as summary. This method is used for <ListPreference/> or <RingtonePreference/> where you would like to see current value. Summary in this case is string but for <SwitchPreference/> it's boolean. Either you can ignore these boolean summary or can using the instanceof you can avoid exception.
