Android SQLite query WHERE clause

Is this correct way to form SQLite query with WHERE and its arguments, because I am getting error the bind value at index 4 is null.

public Cursor getBankomatLocation(){
    SQLiteDatabase db = getReadableDatabase();
    SQLiteQueryBuilder qb = new SQLiteQueryBuilder();

    String [] sqlSelect = {"0 _id", "Naslov", "Kraj"};
    String sqlTables="Bankomati_db";
    String sqlWhere = "Banka=? AND(Posta BETWEEN ? AND ? OR Kraj = ?)";
    String [] args ={selectedBank, selectedPostaPod, selectedPostaNad, selectedKraj};
    Log.d("getBankomatLocation", "selectedBank" + selectedBank);
    qb.setTables(sqlTables);
    Cursor c =qb.query(db, sqlSelect, sqlWhere, args, null, null, null);
    c.moveToFirst();
    return c;
}

SQL statement: SELECT Naslov, Kraj FROM Bankomati_db Where Banka = SelectedBank AND (Posta BETWEEN selectedPostaPod AND SelectedPostaNad OR kraj = selectedKraj)
