The Blog Reader app will teach me 
one of the most common and 
important uses of an Android app: 
downloading data from the Internet 
and displaying it in a list. I will 
investigate the Model-View-Controller 
design pattern that is essential for all Android apps, 
learn how to request data from the web, 
parse and use information in JSON 
format, and utilize the built-in 
Android ListActivity and adapter. 
I also see how to display a webpage 
inside an app.
