title: Intent Filter on Android
body: <p>I am reading the intent filter of the android, and having a few question need to ask.</p>
  
  <ol>
  <li><p>Do they match the filter within the same application or all of the applications?</p></li>
  <li><p>The scheme within the data tag, I have looked on the documentation on the android sdk website but no idea what it mean. It say <strong>scheme://host:port/path</strong> or <strong>pathPrefix</strong> or <strong>pathPattern</strong></p></li>
  </ol>
  
  <p>What is the host port and path .... What does the path relate to?</p>
