Answer 1

I only suggest you to write this code in your previous question, so might be below is the main issue that is causing problem.

Try to declare your

files = new File(Environment.getExternalStorageDirectory()+ "/Audio File/");

as a

private static final String files = new String(
            Environment.getExternalStorageDirectory() + "/Audio File/");

You have declare a path as a File, so change it with a String and then try.
