Fixed version (ground truth):

  if (card_list != null) {
    empty.setVisibility(View.GONE);
    loading.setVisibility(View.GONE);
    card_list.setEmptyView(loading);
  }
  adapter.changeCursor(null);

  c.setProjection(AdapterCardsFilter.COLS_USED);
  SharedPreferences pref=PreferenceManager.getDefaultSharedPreferences(getActivity());
  ArrayList<CharSequence> sel_args=new ArrayList<>();
  String[] sort_col=getResources().getStringArray(R.array.sort_card_col);

  String sort="String_Node_Str";
  for (  String s : sort_pref) {
    int i=Integer.parseInt(s);
    if (i == 1)     break;
    sort+=sort_col[i] + "String_Node_Str";
  }
  c.setSortOrder(sort + sort_col[1]);
  String curSel=pref.getString(Prefs.FILT_SET,"String_Node_Str");

  boolean filt_curse=pref.getBoolean(Prefs.FILT_CURSE,true);
  if (!filt_curse) {
    sel+="String_Node_Str" + TableCard._META_CURSER + "String_Node_Str";
