Well there's a function to merge Audio or Video files

public static boolean mergeMediaFiles(boolean isAudio, String sourceFiles[], String targetFile) {
        try {
            String mediaKey = isAudio ? "soun" : "vide";
            List listMovies = new ArrayList<>();
            for (String filename : sourceFiles) {
                listMovies.add(MovieCreator.build(filename));
            }
            List listTracks = new LinkedList<>();
            for (Movie movie : listMovies) {
                for (Track track : movie.getTracks()) {
                    if (track.getHandler().equals(mediaKey)) {
                        listTracks.add(track);
                    }
                }
            }
            Movie outputMovie = new Movie();
            if (!listTracks.isEmpty()) {
                outputMovie.addTrack(new AppendTrack(listTracks.toArray(new Track[listTracks.size()])));
            }
            Container container = new DefaultMp4Builder().build(outputMovie);
            FileChannel fileChannel = new RandomAccessFile(String.format(targetFile), "rws").getChannel();
            container.writeContainer(fileChannel);
            fileChannel.close();
            return true;
        }
        catch (IOException e) {
            Log.e("MYTAG", "Error merging media files. exception: "+e.getMessage());
            return false;
        }
    }

• If you got Audios, isAudio should be true. if you got videos isAudio should be false

• sourceFiles[] array should contain the destinations of the media files such as

  /sdcard/my_songs/audio_1, /sdcard/my_songs/audio_2, /sdcard/my_songs/audio_3

• targetFile is your final audio merged file should be somthing like

  /sdcard/my_songs/final_audio_1

• If you deal with large files it's preferred to merge file in background, you can use AsynkTask
