======

4+
This Network Usage sample app does the following:
5+
6+
-- Downloads an XML feed from StackOverflow.com for the most recent posts tagged "android".
7+
8+
-- Parses the XML feed, combines feed elements with HTML markup, and displays the resulting HTML in the UI.
9+
10+
-- Lets users control their network data usage through a settings UI. Users can choose to fetch the feed
11+
when any network connection is available, or only when a Wi-Fi connection is available.
12+
13+
-- Detects when there is a change in the device's connection status and responds accordingly. For example, if
14+
the device loses its network connection, the app will not attempt to download the feed.
