Running a program on a server

I want to build an Android application that downloads an XML file from a web server and displays its contents in a readab开发者_StackOverflowle format. My problem is generating that XML file. Basically I want to run a program, say, every 30 minutes that downloads a web page (as that data is not easily accessible), parses it, generates said XML file and puts it somewhere for the Android application to download. Now, I was writing a Java application to do this, but it came to me: where am I going to run this? I thought of having a laptop permanently running at home, but there must be a better alternative. I have online hosting, but it is very simple. It does not even include SSH.

Any ideas?

Edit: as per your suggestions, I checked and yes, my cPanel does have a "Cron Jobs" section. I will now investigate it. Thank you so much for your help.

http://www.setcronjob.com/ allows you to trigger a web page request once every hour, which might be good enough.

I have not actually tried it, but it sounds like a good solution.

you need to rent a server which will generate your html and also serve the content to your app. Not expensive if you get a VPS or cloud server.
