title: Set default value in MultiSelectListPreference
body: <p>I want to check default value in MultiSelectListPreference from code.
  I've seen <a href="https://stackoverflow.com/questions/15628558/how-to-set-multiple-default-values-in-a-multiselectlistpreference">this question</a> but did not find any solution.
  Please suggest a way to do it.</p>

  <pre><code>    if (notificatinType != null) {
          multi_list_preference.setEntries(notificatinType);
      }
      if (notificationTypeValue != null) {
          multi_list_preference.setEntryValues(notificationTypeValue);
      }
      Boolean[] entryChecked = { true, false, true };
      //String tryCheck = "[1, 2]";
      multi_list_preference.setDefaultValue(entryChecked);        
      if (notificationSelected != null) {
          multi_list_preference.setDefaultValue(entryChecked);
      }
