Hello Friends, Today I will tell you file uploading in android using web service in PHP. Basically we will call web service developed in PHP using AsyncTask in android to upload file and we will get file name and file type in response.
PHP Code for Web Service

<?php date_default_timezone_set("Asia/Kolkata"); define("KEY", "ABCD"); //it could be anything secret key which will be shared to authorised developer only to access web service in their application define("SITE_URL","https://zatackcoder.com"); //instead of zatackcoder.com put your website url |
