"My" Code...

                FileInputStream fis1 = new FileInputStream("/sdcard/1408586436107.mp3");  // first source file
                FileInputStream fis2 = new FileInputStream("/sdcard/1408586281745.mp3");//second source file
                SequenceInputStream sis = new SequenceInputStream(fis1, fis2);
                FileOutputStream fos = new FileOutputStream("/sdcard/juntos4.mp3");//destinationfile

                int temp;

                try {
                    while ((temp = sis.read())!= -1){

                        fos.write(temp);

                    }

                    fis1.close();
                    fis2.close();
                    sis.close();
                    fos.close();

                } catch (IOException e) {

create the FILE not the directory!

newFile.createNewFile();


FileInputStream fistream1 = new FileInputStream(newFile1 );  // first source file
    FileInputStream fistream2= new FileInputStream(newFile2 );//second source file
    Vector<FileInputStream> v = new Vector<FileInputStream>();
    v.add(fistream1);
    v.add(fistream2);
    SequenceInputStream sistream = new SequenceInputStream(fistream1, fistream2);

    if(!newFile.exists()){
        newFile.createNewFile();
        FileOutputStream fostream=new FileOutputStream(newFile, true);
        int temp;

        while( ( temp = sistream.read() ) != -1)
        {
            System.out.print( (char) temp ); // to print at DOS prompt
            fostream.write((byte)temp);   // to write to file
        }

        fostream.close();
        sistream.close();
        fistream1.close();
        fistream2.close();
    }
