我试图使用jaudiotagger更改音频文件的专辑封面,但它无法正常工作。关于这个主题有很多问题,但没有一个满足我的要求。艺术家,音频名称,专辑等其他字段已成功更新,但专辑图片保持不变。
我用来更改图稿的代码:
public void changeAlbumArt(Uri data) {
Artwork cover = null;
try {
AudioFile f = null;
try {
f = AudioFileIO.read(new File(storageUtil.loadAudio().get(storageUtil.loadAudioIndex()).getData()));
} catch (CannotReadException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
} catch (TagException e) {
e.printStackTrace();
} catch (ReadOnlyFileException e) {
e.printStackTrace();
} catch (InvalidAudioFrameException e) {
e.printStackTrace();
}
Tag tag = null;
if (f != null) {
tag = f.getTag();
}
try {
if(tag!=null) {
cover = ArtworkFactory.createArtworkFromFile(new File(data.getPath()));
tag.deleteArtworkField();
tag.setField(cover);
}
} catch (FieldDataInvalidException e) {
e.printStackTrace();
}
try {
if (f != null) {
f.commit();
}
} catch (CannotWriteException e) {
e.printStackTrace();
}
} catch (Exception e) {
e.printStackTrace();
}
File file = new File(storageUtil.loadAudio().get(storageUtil.loadAudioIndex()).getData());
Uri uri = Uri.fromFile(file);
Intent scanFileIntent = new Intent(
Intent.ACTION_MEDIA_SCANNER_SCAN_FILE, uri);
sendBroadcast(scanFileIntent);
}
答案 0 :(得分:0)
我有一点工作,但由于jaudiotagger需要一些在android中没有的io文件,所以已经恢复到jid3。 另外,对于android Gingerbread +写入外部存储需要SAF框架。我已经设法修改了jid3库,所以它可以工作但只适用于mp3。
用于mp3文件:
public String setMp3AlbumArt(File SourceFile, byte[] bytes)
throws Exception {
String error = null;
try {
MP3File musicFile = (MP3File) AudioFileIO.read(SourceFile);
AbstractID3v2Tag tag = musicFile.getID3v2Tag();
if (tag != null) {
Artwork artwork = null;
try {
artwork = ArtworkFactory.createArtworkFromFile(SourceFile);
} catch (IOException e) {
e.printStackTrace();
error = e.getMessage();
}
if (artwork != null) {
artwork.setBinaryData(bytes);
tag.deleteArtworkField();
tag.setField(artwork);
musicFile.setTag(tag);
musicFile.commit();
} else {
artwork.setBinaryData(bytes);
tag.addField(artwork);
tag.setField(artwork);
musicFile.setTag(tag);
musicFile.commit();
}
}
} catch (CannotReadException | IOException | TagException
| ReadOnlyFileException | InvalidAudioFrameException e) {
error = e.getMessage();
}
return error;
}
