android从byte[]字节数组中播放mp3音乐

private void playMp3(byte[] mp3SoundByteArray) {

    try {

        // create temp file that will hold byte array

        File tempMp3 = File.createTempFile("kurchina", "mp3", getCacheDir());

        tempMp3.deleteOnExit();

        FileOutputStream fos = new FileOutputStream(tempMp3);

        fos.write(mp3SoundByteArray);

        fos.close();

        // Tried reusing instance of media player

        // but that resulted in system crashes...  

        MediaPlayer mediaPlayer = new MediaPlayer();

        // Tried passing path directly, but kept getting 

        // "Prepare failed.: status=0x1"

        // so using file descriptor instead

        FileInputStream fis = new FileInputStream(tempMp3);

        mediaPlayer.setDataSource(fis.getFD());

        mediaPlayer.prepare();

        mediaPlayer.start();

    } catch (IOException ex) {

        String s = ex.toString();

        ex.printStackTrace();
