Android Media player error (1,-4) while playing an audio from Assets folder

Question

I need your help. I tried to play an audio file stored in Assets folder but an error occurred.

Here are my code:

try{
  if (player.isPlaying()) {
    player.stop();
    player.release();
  }
}catch(Exception e){
  Toast.makeText(this, "an exception occurred", Toast.LENGTH_LONG).show();
  e.printStackTrace();
}
try{
  AssetFileDescriptor afd = BeeDailyConvo.this.getAssets().openFd("sounds/hello_kr.wma");
  player.setDataSource(afd.getFileDescriptor(),afd.getStartOffset(),afd.getLength());
  player.prepare();
  player.start();
}catch(Exception e){
  e.printStackTrace();
}

And here are my logcat:

06-16 22:39:53.330: W/MediaPlayer(13490): info/warning (1, 26)
06-16 22:39:53.330: E/MediaPlayer(13490): error (1, -4)

Could you please explain what's wrong with my code?

Thank you in advance

Regards,

Priska

This issue has been SOLVED.

The asset file descriptor must be closed before preparing the player. This is how I solved the problem:

player = new MediaPlayer();
AssetFileDescriptor afd = BeeDailyConvo.this.getAssets()
  .openFd("sounds/"+file);
player.setDataSource(afd.getFileDescriptor(),afd.getStartOffset(),afd.getLength());
afd.close();**//just added this line**
player.prepare();
player.start();

Here you can see all Error codes Media player Error codes

-4 error code indicates you have given invalid arguments.

Put your code in try catch block.

Try Using

    try {
          AssetFileDescriptor afd = CustomListViewActivity.this.getAssets()
                    .openFd("sounds/hello_kr.wma");
            player.setDataSource(afd.getFileDescriptor());
        } catch (IllegalArgumentException e) {
            e.printStackTrace();
        } catch (IllegalStateException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }

thanks for your reply. I have tried your suggestion, no more error(1,-4) but it gives me another error, the media player cannot be created. here is my logcat 06-16 23:33:53.350: W/System.err(14869): at android.media.MediaPlayer.setDataSource(Native Method) – Priska Aprilia Jun 16 '12 at 16:35

Unfortunately there is very little information about MediaPlayer error codes available for some reason. However I suggest you try putting your sound file inside res/raw/ instead of your assets.

EDIT:

Start here with the Using the MediaPlayer section in the developer docs. This will show you how to set up and play the sound properly.

EDIT 2:

turns out that can do it from assets see this question: Play audio file from the assets directory

Actually I stored the audio file name in a database and the real audio files in assets folder. I use sqlite query to retrieve the file name from the database, and the audio in assets folder will be played once a specific audio file is clicked. Because I don't exactly know which audio is clicked, so I can't place the audio files beneath the res/raw folder. any idea? – Priska Aprilia Jun 16 '12 at 16:16
thanks for your reply. Yes that's what I have done but it gives me an error like I said before. – Priska Aprilia Jun 16 '12 at 16:23

I don't think that wma files are supported.

http://developer.android.com/guide/appendix/media-formats.html

I noticed that you didn't specify the audioStreamType

mediaPlayer.setAudioStreamType(AudioManager.STREAM_MISIC);

Yes I noticed that too I have converted my audio file to .wav format, but still same error "unable to create media player". Where do I have to place the player.setAudioStream(AudioManager.STREAM_MUSIC) line? edited : anyway there is setAudioSteamType function instead of setAudioStream. – Priska Aprilia Jun 17 '12 at 01:00

use this way it will solve your problem :)

    public void playBeep() {
    try {

        if (m.isPlaying()) {
            m.stop();
            m.release();
            m = new MediaPlayer();
        }
        AssetFileDescriptor descriptor = getAssets().openFd("mp3 name.mp3");
        m.setDataSource(descriptor.getFileDescriptor(), descriptor.getStartOffset(), descriptor.getLength());
        descriptor.close();

        m.prepare();
        m.setVolume(1f, 1f);
        m.setLooping(true);
        m.start();
    } catch (Exception e) {
    }
}
