| <p>This class explains the basic tasks involved in connecting to the network, |
| monitoring the network connection (including connection changes), and giving |
| users control over an app's network usage. It also describes how to parse and |
| consume XML data.</p> |
| |
| <p>This class includes a sample application that illustrates how to perform |
| common network operations. You can download the sample (to the right) and use it |
| as a source of reusable code for your own application.</p> |
| |
| <p>By going through these lessons, you'll have the |
| fundamental building blocks for creating Android applications that download |
| content and parse data efficiently, while minimizing network traffic.</p> |
