How to get and set (change) ID3 tag (metadata) of audio files?

I think this is what you are looking for MyID3 library to set and get tags for media file.

Download this jar file MyID3_for_android and add it to your project's build path.here is the sample code. here pathdata is the file path of the audio file.

            File src = new File(pathdata);            MusicMetadataSet src_set = null;            try {                src_set = new MyID3().read(src);            } catch (IOException e1) {                // TODO Auto-generated catch block                e1.printStackTrace();            } // read metadata            if (src_set == null) // perhaps no metadata            {                Log.i("NULL", "NULL");            }            else            {                try{                    IMusicMetadata metadata = src_set.getSimplified();                    String artist = metadata.getArtist();                      String album = metadata.getAlbum();                      String song_title = metadata.getSongTitle();                     Number track_number = metadata.getTrackNumber();                     Log.i("artist", artist);                    Log.i("album", album);                }catch (Exception e) {                    e.printStackTrace();                }                File dst = new File(pathdata);                MusicMetadata meta = new MusicMetadata("name");                meta.setAlbum("Chirag");                meta.setArtist("CS");                try {                    new MyID3().write(src, dst, src_set, meta);                } catch (UnsupportedEncodingException e) {                    // TODO Auto-generated catch block                    e.printStackTrace();                } catch (ID3WriteException e) {                    // TODO Auto-generated catch block                    e.printStackTrace();                } catch (IOException e) {                    // TODO Auto-generated catch block                    e.printStackTrace();                }  // write updated metadata            }

Happy Coding :)

Actually, FasteKerinns's code is quite good. You should just change

new MyID3().write(src, dst, src_set, meta);

to

new MyID3().update(src, src_set, meta);

which means you don't need dst variable at all.

Additionaly, I have this piece of code which refreshes song that is modified in MediaStore:

 scanner=new MediaScannerConnection(getApplicationContext(),              new MediaScannerConnectionClient() {          public void onScanCompleted(String path, Uri uri) {              scanner.disconnect();       }      public void onMediaScannerConnected() {              scanner.scanFile(path, "audio/*");          }  });  scanner.connect();

And most important point is that the edited ID3 tags were shown only into the my app.

If you edit the file then anybody will see that. You can create your own database of mediafiles (like Android's database) and just store the modified data there.
