android 中的 JAudiotagger java.lang.VerifyError

Question

我正在尝试创建一个参考这些的音频标签编辑器

http://www.jthink.net/jaudiotagger/

和

JAudioTagger and Android - Change a value in an mp3?

和

Jaudiotagger ID3 TAG for android - can set artwork but cannot set other fields

需要将哪个库导入到项目中，这样我就不会得到java.lang.VerifyError

我正在尝试使用这个库编写代码

jaudiotagger-2.2.5.jar

我从这里找到的

https://bitbucket.org/ijabz/jaudiotagger/downloads

这是代码

try {
    File file = new File(Data);
    TagOptionSingleton.getInstance().setAndroid(true);
    AudioFile audioFile = AudioFileIO.read(file);
    Tag newTag = audioFile.getTag();
    newTag.setField(FieldKey.ALBUM,"October");
    newTag.setField(FieldKey.ARTIST,"U2");
    audioFile.commit(); 
} catch (CannotReadException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
} catch (IOException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
} catch (TagException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
} catch (ReadOnlyFileException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
} catch (InvalidAudioFrameException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
} catch (CannotWriteException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
}

这是日志猫

Answer 1

阅读错误，很容易指出下面这行是导致Verify错误的原因

TagOptionSingleton.getInstance().setAndroid(true);

Could not find method org.jaudiotagger.tag.TagOptionSingleton.getInstance, referenced from method com.example.scrlltabs3.songManagerDialog.onClick

谷歌搜索问题我遇到了以下 Whosebug question/answer，它描述了相同的问题并通过替换提供了解决方案：

audioFile.commit();

与

AudioFileIO.write(audioFile)

请参阅 here 问题和上述解决方案。如果这解决了您的问题，请不要忘记给回答者 Paul Taylor 投赞成票。

java.lang.verifyError 当 JVM 的字节码验证程序在执行前尝试验证所有字节码并在发现不一致时失败并且这些不一致可能由于许多因素而增加作为

在运行时间内针对一个库进行编译并使用另一个库
单独编译 class 有其他 classes 依赖它
教程link中列出的其他内容

可以找到关于 VerifyError 的详细解释和示例 here。

请参阅上面的示例 link，其中演示了 JVM 是如何抛出验证错误的。
