Android, How to play WAV file programmatically

I have may file.wav in my directory. Then in parallel, I have to play is with an mp3 file.

See the code below:

String recordedFile = "/storage/sdcard0/app/file.wav";
MediaPlayer recordedSong = new MediaPlayer();

try {
  recordedSong = MediaPlayer.create(ctx, 
  Uri.fromFile(recordedFile));
  recordedSong.prepare();
  recordedSong.start();
}
  catch (Exception e) {
}

Error: Creation failed and it throws IOException

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+"/"+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();
        } 
    }
