Android app programming different from game programming?
<p>I'm making a business application but I've been following the tutorial of Beginning Android Games by Mario Zechner (I intended to make a game first). </p>

<p>In Mario's tutorial he uses one activity for the entire app, and doesn't really use the xml layouts. He also uses the assetmanager directly instead of the Resource object and created his own render thread. </p>

<p>What are some key differences between developing a business app and game app programmatically? </p>
