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，以便我不会获得java.lang.VerifyError

我正在尝试使用此库的代码

jaudiotagger-2.2.5.jar

我从这里找到了

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，很容易指出以下行导致Verify错误

TagOptionSingleton.getInstance().setAndroid(true);

无法找到方法 org.jaudiotagger.tag.TagOptionSingleton.getInstance，引用自方法com.example.scrlltabs3.songManagerDialog $ 3.onClick

谷歌搜索问题我遇到了以下stackoverflow问题/答案描述相同的问题，并通过替换提供解决方案：

audioFile.commit();

带

AudioFileIO.write(audioFile)

请参阅here问题以及上述解决方案。如果这解决了你的问题，那么不要忘记给回答者保罗泰勒作为一个upvote。
