MediaPlayer附加的搜寻栏中的缓冲更新未达到100％

标签： android android-mediaplayer audio-streaming seekbar buffering

在这里，我开发了一个应用程序，可以流式传输存储在服务器中的音频文件。 这是使用MediaPlayer类完成的。歌曲的当前播放位置和缓冲级别显示在自定义Seekbar中。
到目前为止，我已经设法将缓冲进度显示为seekbar的次要进度，将seekbar的主要进度与MediaPlayer播放同步，并在单击相应按钮时播放，暂停和停止播放。
但是现在，我陷入了一个问题，即缓冲进度未显示出大于86％到89％的水平，这同样反映在搜索栏的次要进度上，即，搜索栏的缓冲进度在之后不会增加（86-89％）。我已经捕获了缓冲百分比在日志中，并在下面附加相关的日志详细信息。

我还将在歌曲搜索栏中附上歌曲缓冲级别的屏幕截图，并用红色突出显示。Screenshot of buffered level
我已经在网络上进行了大量研究以寻找其原因和解决方案，但没有一个对我有用。即使在将搜索栏拖到缓冲歌曲位置之前的位置（屏幕截图中的白条）），大约在86后％，歌曲播放没有任何问题，但如屏幕截图所示，次要进度被卡住了。

这是在MediaPlayer和SeekBar之间进行整体交互的代码

在Songs.java中创建的Songs类的代码段 

private void primarySeekBarProgressUpdater() {         /**method to update 
primary progress of seekbar**/
    seekBar.setProgress((int) (((float) mediaPlayer.getCurrentPosition() / 
mediaFileLengthInMilliseconds) * 100));
    tvElapsedTime.setText(getTimeString(mediaPlayer.getCurrentPosition()));
    if (mediaPlayer.isPlaying()) {
        Runnable notification = new Runnable() {
            @Override
            public void run() {
                primarySeekBarProgressUpdater();
            }
        };
        handler.postDelayed(notification, 1000);
    }
}

@Override
public void onClick(View v) {         /**onClick event handler to handle 
play, pause and stop button clicks for mediaplayer **/
    if (v.getId() == R.id.buttonPlay) {
        if (mediaPlayer != null) {
            mediaPlayer.start();
            imPause.setVisibility(View.VISIBLE);
            imPlay.setVisibility(View.INVISIBLE);
            primarySeekBarProgressUpdater();
        }
    } else if (v.getId() == R.id.buttonPause) {
        mediaPlayer.pause();
        imPlay.setVisibility(View.VISIBLE);
        imPause.setVisibility(View.INVISIBLE);
        primarySeekBarProgressUpdater();
    } else if (v.getId() == R.id.buttonStop) {
        if (mediaPlayer != null) {
            mediaPlayer.stop();
            seekBar.setProgress(0);
            seekBar.setSecondaryProgress(0);
            imPlay.setVisibility(View.VISIBLE);
            imPause.setVisibility(View.INVISIBLE);
        }
    } else if (v.getId() == R.id.buttonPlay && !itemClicked) {
        Toast.makeText(getApplicationContext(), "Please touch a song to start 
playing it.", Toast.LENGTH_LONG).show();
    }
}

@Override
public boolean onTouch(View v, MotionEvent event) {   
    if (v.getId() == R.id.seekBar) {
        /** Seekbar onTouch event handler. Method which seeks MediaPlayer to 
seekBar primary progress position*/
        if (mediaPlayer != null) {
            SeekBar sb = (SeekBar) v;
            int playPositionInMilliseconds = (mediaFileLengthInMilliseconds / 
    100) * sb.getProgress();
            mediaPlayer.seekTo(playPositionInMilliseconds);

tvElapsedTime.setText(getTimeString(mediaPlayer.getCurrentPosition()));
        }
    }
    return false;
}

public String getTimeString(long millis) {     /**method to convert passed 
milliseconds to minutes and seconds and return in form of string**/
    StringBuffer buf = new StringBuffer();
    int mins = (int) ((millis % (1000 * 60 * 60)) / (1000 * 60));
    int secs = (int) (((millis % (1000 * 60 * 60)) % (1000 * 60)) / 1000);

    buf.append(String.format("%02d", mins)).append(":")
            .append(String.format("%02d", secs));
    return buf.toString();
}


@Override
protected void onPause() {
    super.onPause();
}

@Override
protected void onDestroy() {
    super.onDestroy();
}

@Override
public void onBackPressed() {

    if (mediaPlayer != null) {
        mediaPlayer.stop();
        mediaPlayer.release();
    }

    super.onBackPressed();
}
  

下面是列表项（即单击任何歌曲）时相同类别的代码段

        list.setAdapter(adapter);
        list.setOnItemClickListener(new AdapterView.OnItemClickListener() {

            @Override
            public void onItemClick(AdapterView<?> parent, View view, final 
            int position, long id) {
                list.setItemChecked(position, true);
                url = songdetails.get(position).getUrl(); // your URl

                if (mediaPlayer != null) {
                    mediaPlayer.stop();
                }

                mediaPlayer = new MediaPlayer(); // create instance of 
mediaplayer here
                mediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
                try {
                    mediaPlayer.setDataSource(url);
                    mediaPlayer.prepare();
                    itemClicked = true;

                } catch (IOException e) {
                    e.printStackTrace();
                }
                mediaFileLengthInMilliseconds = mediaPlayer.getDuration();// 
gets the song length in milliseconds from URL

                mediaPlayer.setOnPreparedListener(new 
MediaPlayer.OnPreparedListener() {
                    @Override
                    public void onPrepared(MediaPlayer mp) {
                        mp.start();
                        imPlay.setVisibility(View.INVISIBLE);
                        imPause.setVisibility(View.VISIBLE);
                        primarySeekBarProgressUpdater();

tvEndTime.setText(getTimeString(mediaFileLengthInMilliseconds));
                        mediaPlayer.setOnBufferingUpdateListener(new 
MediaPlayer.OnBufferingUpdateListener() {
                            @Override
                            public void onBufferingUpdate(MediaPlayer mp, int 
percent) {
                                if (percent < seekBar.getMax()) {
                                    seekBar.setSecondaryProgress(percent);  
/** This is the point where secondary progress is set on buffering update **/
                                    Log.i("Buffering", "" + percent);   /** 
and this is the point where tat buffered percentage is captured in logcat **/
                                }
                            }
                        });
                        mediaPlayer.setOnCompletionListener(new 
MediaPlayer.OnCompletionListener() {
                            @Override
                            public void onCompletion(MediaPlayer mp) {
                                mp.start();
                            }
                        });
                    }
                });
                primarySeekBarProgressUpdater();
            }
        });

所以我的缓冲进度没有达到我期望的100％。
