Asset Manager, OpenFd?

I have a file in my assets folder I wish to access, I do so by:

AssetFileDescriptor fileSound = am.openFd("myfilepathetc/mymp3.mp3");


But I get the error:

This file can not be opened as a file descriptor; it is probably compressed


After some googling it appears that I need to add an extension to my file, such as .mp3 as Android compresses stuff in the assets folder unless its of a format already compressed, the only problem is, my file is already an mp3 and it still wont open.

Is there a way of uncompromising it? Or does anyone have a better way to access an mp3 from assets, please note I do not want to access it from the raw folder for reasons i wont bother going into.

Answer

Why don't you use this instead :

private void playAudioSound() {
    try {
        AssetFileDescriptor afd = context.getAssets().openFd("sounds/jad0005a.wav");
        MediaPlayer player = new MediaPlayer();
        player.setDataSource(afd.getFileDescriptor());
        player.prepare();
        player.start();
    } catch (IOException e) {
        e.printStackTrace();
    }
}
