java.io.IOException：準備失敗：狀態= 0x1在Android中

我試圖播放ListView中的文件，其中mediaPlayer類。java.io.IOException：準備失敗：狀態= 0x1在Android中

像這樣：

public void initializeViews() { 
    Intent intent = getIntent(); 
    String fName = intent.getStringExtra("fileName"); 
    fileName = (TextView) findViewById(R.id.fileName); 
    duration = (TextView) findViewById(R.id.songDuration); 
    seekbar = (SeekBar) findViewById(R.id.seekBar); 
    playBtn = (ImageButton) findViewById(R.id.media_play); 
    try { 
     mediaPlayer = new android.media.MediaPlayer(); 
     mediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC); 
     mediaPlayer.setDataSource(fName); 
     mediaPlayer.prepare(); 
    } 
    catch (IOException e) { 
     e.printStackTrace(); 
    } 
    fileName.setText(fName.substring(fName.lastIndexOf("/") + 1)); 
    finalTime = mediaPlayer.getDuration(); 
    seekbar.setOnSeekBarChangeListener(mOnSeek); 
    seekbar.setMax((int) finalTime); 
    seekbar.setClickable(true); 
    mediaPlayer.start(); 
    timeElapsed = mediaPlayer.getCurrentPosition(); 
    seekbar.setProgress((int) timeElapsed); 
    durationHandler.postDelayed(updateSeekBarTime, 200); 
}

我在互聯網上搜索，而最的問題是檢查文件的路徑，但fName得到了完整路徑的文件。但我不知道它顯示例外：

您可以添加更多日誌嗎？ –

@ TungD.Nguyen我更新了我的日誌。 –

可能造成的閱讀權限。通過在manifest文件中插入權限進行修復：

<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />

我添加了權限。但是這個錯誤繼續出現。 –
