java.io.IOException: Hazırla başarısız .: status = 0x1 Android

Question

mediaPlayer sınıfında ListView dosyasında bir dosyayı oynatmaya çalıştım. Bunun gibi

:

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); 
} 

internette arama ve çoğu soru dosyaya yolunu kontrol olmakla fName bir dosyanın tam yolunu aldık. Ama durum gösteren bilmiyorum:

java.io.IOException: Prepare failed.: status=0x1

Tüm günlük uygulama durum oluştuğunda: iznine okuyarak neden

Answer 1

mümkün. manifest dosyasındaki izni ekleyerek düzeltin:

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