What are Intent Filters exactly?

Question

I\'ve read lots of articles about intent filters and I really can\'t understand exactly what they do?

so please if anybody can explain to me with a clear example what is

Answer 1

Simply put, Intent filters are a way of telling the OS how to launch/communicate with the different activities/services/broadcast receivers in your app. So for example, if you want links that start with http://www.mycompany.com to lead people into your app, an intent filter is the way to accomplish that. Once its setup, anytime someone clicks on a link that starts with that (in any app) the user will be presented with the option to use your app to view that page. You've probably seen this with youtube urls. Likewise, if you want the 'share' link commonly seen in many apps to list your app, would use an intent filter to do that.

hope this helps...
