values.put(MediaStore.MediaColumns.TITLE, SOME_NAME_HERE);

values.put(MediaStore.MediaColumns.TIMESTAMP, System.currentTimeMillis());

ContentResolver contentResolver = new ContentResolver();

Uri base = MediaStore.Audio.INTERNAL_CONTENT_URI;

}

/* Receive the real path as String */

String path = contentResolver.getDataFilePath(newUri);

/* Set Audio Source, Format, Encode and File */
