I would look up the whole directory.. and search every filename for .jpg or .mp3 at the end with .endswith()

File sdCardRoot = Environment.getExternalStorageDirectory();
File yourDir = new File(sdCardRoot, "path");
for (File f : yourDir.listFiles()) {
    if (f.isFile())
        String name = f.getName();
        if(name.endsWith(".mp3)){
            //Call MP3 player
        }
        else if(name.endsWith(".jpg") || name.endsWith(".png")){
            //Do something with your picture
        }
}

and you should be able to launch the mp3-player with

Intent intent = new Intent();  
intent.setAction(android.content.Intent.ACTION_VIEW);  
File file = new File(YOUR_SONG_URI);  
intent.setDataAndType(Uri.fromFile(file), "audio/*");  
startActivity(intent);

Try something like this

    File sdCardRoot = Environment.getExternalStorageDirectory();
    File yourDir = new File(sdCardRoot, "path");
    File[] mp3Files = yourDir.listFiles(new FilenameFilter() {
        public boolean accept(File dir, String name)
        {
            return (name.endsWith(".mp3"));
        }
    });
