android中的JAudiotagger java.lang.VerifyError

Question

我正在尝试创建一个引用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

项目中需要导入哪个库才不会得到java.lang.VerifyError

我正在尝试使用这个库的代码

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();
}

Answer 1

阅读错误，很容易指出以下行导致Verify错误

TagOptionSingleton.getInstance().setAndroid(true);

找不到方法 org.jaudiotagger.tag.TagOptionSingleton.getInstance，引用自 com.example.scrlltabs3.songManagerDialog$3.onClick 方法

谷歌搜索问题我遇到了以下 stackoverflow 问题/答案，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，请不要忘记给该答案中的回答者 Paul Taylor 点赞。

java.lang.verifyError 发生在 JVM 的字节码验证器在执行之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多种因素而增加，例如

• 针对一个库编译并在运行时使用另一个库
• 类的单独编译有其他类依赖于它
• 教程链接中列出的其他内容

有关VerifyError 的详细说明和示例可以在here 找到。

请参阅上面链接中的示例，这些示例演示了 JVM 如何引发验证错误。
