java.lang.NullPointerException :println требуется сообщение

Я получаю сообщение об ошибке :java.lang.NullPointerException :println требуется сообщение, когда я вызываю этот метод:

lst_info = new HashMap<String, String>();
SystemDatabaseHandler db = new SystemDatabaseHandler(getApplicationContext());
lst_info = db.getLstInfo(sql_id);

SystemDatabaseHandler:

public HashMap<String, String> getLstInfo(int id){
    HashMap<String, String> lst_temp;
    lst_temp = new HashMap<String, String>();

    String selectQuery = "SELECT * FROM dkr_lst_lst WHERE lst_id = " + id;
    SQLiteDatabase db = this.getWritableDatabase();
    Cursor cursor = db.rawQuery(selectQuery, null);
    if (cursor.moveToFirst()) {
        do {
            Log.d("sql_id", cursor.getString(0));
            lst_temp.put("sql_id", cursor.getString(0));
        }while (cursor.moveToNext());
    } 
    cursor.close();
    db.close();
    return lst_temp;
}

Log.d ("sql _id", cursor.getString (0 )); возвращается:
