从Firebase Storage Android更快地进行音频流传输

如何解决从Firebase Storage Android更快地进行音频流传输

我是Android的新手。我正在开发online music streaming app。音频文件位于Firebase Storage中。大小为3 mb。我正在使用Android中内置的Media Player库流式传输音频文件。

它首先获取整个音频，然后开始播放。提取整个音频所花费的时间长达50秒到60秒，具体时间取决于网络连接。我想更快地获取音频文件。将音频分为夹头有助于实现这一目标。但是我不知道怎么做。

搜索Google时，我发现Exo Player是媒体播放器的最佳替代方法，它将流式传输音频文件，而不是下载音频文件。但是我不知道如何更改exoplayer的代码。

这是我使用的音频流代码：

player.setAudioStreamType(AudioManager.STREAM_MUSIC);
player.setDataSource("url of audio");
player.prepareAsync();

//mp3 will be started after completion of preparing...
player.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {

    @Override
    public void onPrepared(final MediaPlayer player) {
        //        Initialize Runnble
        runnable = new Runnable() {
            @Override
            public void run() {
//                Set Progress on Seek Bar
                seekBar.setProgress(player.getCurrentPosition());
//                Handler Post Delay for 0.5 seconds
                handler.postDelayed(this,500);
            }
        };
//     Get Duration for media player
                int duration = player.getDuration();
//        Convert Millisecond to minute and second
                String sDuration = convertFormat(duration);

//        Set Duration on Text View
                playerDuration.setText(sDuration);

                PB.setVisibility(View.GONE);
                textLoad.setVisibility(View.GONE);
                seekBar.setEnabled(true); 
            }

        });

btPlay.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        try{

            player.start();
            seekBar.setMax(player.getDuration());
            handler.postDelayed(runnable,0);
            btPlay.setVisibility(View.INVISIBLE);
            btPause.setVisibility(View.VISIBLE);
        }
        catch (Exception e) {
            e.printStackTrace();
        }
    }
});
btPause.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        btPlay.setVisibility(View.VISIBLE);
        btPause.setVisibility(View.GONE);
        player.pause();
        handler.removeCallbacks(runnable);
    }
});

btFf.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        int currentPosition = player.getCurrentPosition();
        int duration = player.getDuration();
        if (player.isPlaying() && duration != currentPosition){
            currentPosition = currentPosition +5000;
            playerPostion.setText(convertFormat(currentPosition));
            player.seekTo(currentPosition);
        }
    }
});

btRew.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        int currentPosition = player.getCurrentPosition();
        int duration = player.getDuration();
        if (player.isPlaying() && currentPosition > 5000){
            currentPosition = currentPosition  - 5000;
            playerPostion.setText(convertFormat(currentPosition));
            player.seekTo(currentPosition);
        }
    }
});

seekBar.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() {
    @Override
    public void onProgressChanged(SeekBar seekBar,int progress,boolean fromUser) {
        if(fromUser){
            player.seekTo(progress);
        }
        playerPostion.setText(convertFormat(player.getCurrentPosition()));
    }

    @Override
    public void onStartTrackingTouch(SeekBar seekBar) {

    }

    @Override
    public void onStopTrackingTouch(SeekBar seekBar) {

    }
});
player.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
    @Override
    public void onCompletion(MediaPlayer mp) {
        btPause.setVisibility(View.INVISIBLE);
        btPlay.setVisibility(View.VISIBLE);
        player.seekTo(0);
    }
});




}



@SuppressLint("DefaultLocale")
private String convertFormat(int duration) {
    return String.format("%02d:%02d",TimeUnit.MILLISECONDS.toMinutes(duration),TimeUnit.MILLISECONDS.toSeconds(duration) -
            TimeUnit.MINUTES.toSeconds(TimeUnit.MILLISECONDS.toMinutes(duration)));
}

如何实现更快的流式传输。请帮我一些解决方案。
