Any idea why the Android Music app does not detect the cover image, while the "file manager" does?

I have two mp3 files. One is from an official album unmodified by this library yet when I examine the ID3 tag the version is "3". Then I have another mp3 file which I assign a new ID3 V3 tag with this library. This is running on an Android system and file 1 shows displays the image correctly in both the original music app and the file manager app while file 2, the one I modify with this library only shows the image in the file manager while it does display in the music app. I know it may not be an issue directly to this library but I figured this might be the best place to ask this question. Any idea why I am experiencing this behavior could be?

Here is all I am doing to file 2.

`
Mp3File mp3file = new Mp3File(options.getString("tempPath"));

                       ID3v2 id3v2Tag;               

                       id3v2Tag = new ID3v23Tag();
                       String type = options.getString("thumbnailMime");

                id3v2Tag.setTitle(options.getString("title"));
                id3v2Tag.setAlbum(options.getString("album"));
                id3v2Tag.setAlbumImage(mu.stuff, type);
                mp3file.setId3v2Tag(id3v2Tag);
                mp3file.save(options.getString("toFile"));`

I was experiencing a similar issue where Android could not process MP3 metadata which I wrote with Mp3Tag. I found that changing the album artwork mime type (e.g image/jpeg -> image/png) fixed the problem. It seems to be a bug with Android. Use a photo editor or an online converter to change the album artwork format, and see if that works.
