Android, How to play WAV file programmatically

Try to create raw folder and put your file there, use this

public void number(int num, Context ctx) {
                 AssetManager am;
        try {
            am = ctx.getAssets();
            AssetFileDescriptor afd = am.openFd("android.resource://"+getPackageName+"https://codeutility.org/"+R.raw.your_file_name);
            player = new MediaPlayer();
            player.setDataSource(afd.getFileDescriptor(), afd.getStartOffset(),
                    afd.getLength());
            player.prepare();
            player.start();
            player.setOnCompletionListener(new OnCompletionListener() {

                @Override
                public void onCompletion(MediaPlayer mp) {
                    // TODO Auto-generated method stub
                    mp.release();
                }

            });
            player.setLooping(false);
                    } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } 
    }

I’ve tried @aangwi answer but got FileNodeFoundException

final AssetFileDescriptor afd = myactivity.getResources().openRawResourceFd(R.raw.your_file);
final FileDescriptor fileDescriptor = afd.getFileDescriptor();
MediaPlayer player = new MediaPlayer();
try {
    player.setDataSource(fileDescriptor, afd.getStartOffset(),
    afd.getLength());
    player.setLooping(false);
    player.prepare();
    player.start();
} catch (IOException ex) {
    LOGGER.error(ex.getLocalizedMessage(), ex);
}
