Play audio file from the assets directory

Question

I have the following code:

    AssetFileDescriptor afd = getAssets().openFd("AudioFile.mp3");
    player = new MediaPlayer();
    player.setDataSource(afd.getFileDescriptor());
    player.prepare();
    player.start();

The problem is that, when I run this code, it starts playing all the audio files in the assets directory, in alphabetical order instead of just playing the audio file I requested. What am I doing wrong? Is there a better way to play audio files from the assets directory?

Follow-up question: Is there a difference between keeping audio files in the assets directory and keeping them in the res/raw directory? Besides the fact that they don't get ids if they are in the assets directory. If I move the audio files to the res/raw folder then I have a problem with reusing MediaPlayers because there is no id parameter for setDataSource(). I can't find a good guideline for handling this kind of problem.

Answer 1

player.setDataSource(afd.getFileDescriptor(),afd.getStartOffset(),afd.getLength());
