概述我尝试像这样使用jaudiotagger但崩溃主app.java：    导入java.io.File;    导入java.io.IOException;importorg.jaudiotagger.audio.AudioFile;importorg.jaudiotagger.audio.AudioFileIO;importorg.jaudiotagger.audio.AudioHeader;importorg.jaudiotagger.audi

我尝试像这样使用jaudiotagger
但崩溃

主app.java：
    导入java.io.file;
    导入java.io.IOException;

解决方法:

有两个阻滞剂
在AndroID上使用jaudiotagger：

1-javax.swing

2-javax.imageio

androID不支持这两个类,jaudiotagger使用它们

解决您的问题：
修复源,以便它们不再依赖于这两个JAVAX类
