FileInputStream is used to access local files only. If you want to access the content of an URL you can setup an URLConnection or use something like this:

URL myUrl = new URL("http://online1.tingclass.com/lesson/shi0529/43/32.mp3");
InputStream myUrlStream = myUrl.openStream();
ReadableByteChannel myUrlChannel = Channels.newChannel(myUrlStream);

FileChannel destinationChannel=new FileOutputStream(To_File).getChannel();
destinationChannel.transferFrom(myUrlChannel, 0, sizeOf32MP3);

Or more simply just make a BufferedInputStream from myUrlStream and cycle the read/write operation until EOF is found on myUrlStream.
