我会很感激一些帮助来弄清楚这个异常消息对我说的到底是什么。我能够使用调试器将问题缩小到代码中的特定行。但是，我认为更多信息可以更好地找出代码中的实际问题。

   public static List<ParsedNdefRecord> getRecords(NdefRecord[] records) 
    {
        List<ParsedNdefRecord> elements = new ArrayList<ParsedNdefRecord>();
        for (NdefRecord record : records) {
            if (UriRecord.isUri(record)) {
                elements.add(UriRecord.parse(record));
            } else if (TextRecord.isText(record)) {
                elements.add(TextRecord.parse(record));
            } else if (SmartPoster.isPoster(record)) {
                elements.add(SmartPoster.parse(record));
            }
        }
        return elements;
    }

看来您在运行时类路径中没有有效的番石榴库。确保已将它们添加到 lib 文件夹。
