5 min project - Trigger a PHP Url in Android

I have a PHP script on my server to send email. IF I manually type the following URL in a browser it will send an email : [login to view URL]@icloud.com&subject=Test How do I open or trigger this URL in my Android app ( without opening a browser ) so that when a user clicks a button it triggers the ULR and the email is sent. All I need is the code, i'll insert it in my project
