MagicURLNetwork. MagicURLNetwork is a Java library which includes Mson to support JSON data transfer through networks. To make an URL connection, you only need to know what you want to do and choose an appropriate request method(GET, POST, PUT, HEAD...). You don't need to understand how HTTP, HTTPS and FTP work, and don't need to use any streaming library by yourself, too. You can easily implement a RESTful client program or file uploading/downloading program with this library.
