Building Simple Shoutcast Web Interface for Mobile Part 1

by nolovelust 30. March 2010 21:15

UPDATE 14/01/2011  Shoutcast stopped providing public API for their dataabse. You need to register at http://dev.aol.com/SHOUTcast/ to get your API Key.

After that you can simply edit /App_Code/ScESettings.cs and replece settings with below ones.

 

public static string strURLsearch = "http://api.shoutcast.com/legacy/stationsearch?k=YOURAPIKEY&search=";
public static string strURLbrowse = "http://api.shoutcast.com/legacy/genresearch?k=YOURAPIKEY&genre=";

 

Before all here is the complete script shoutcast-mobile.zip (592.97 kb) and here is the working version at http://mobile.web.tr/shoutcast

This app designed for high-end mobile phones that are capable of doing AJAX requests

Now, lets start from Default.aspx
