TOMMY: That's it for our Android track. To learn more about Android, check out the Android documentation. You can see here there's a lot of information across a variety of Android topics from animations to writing an app for Android Auto. In this track, we've covered a lot of ground. 

We've seen the Java programming language, and we've used that to learn how to write Android views with XML and layouts, how to write activities, and how to model data and persistent to disk. I'm really excited to see the Android apps that you create in your final projects. My name is Tommy, and this is CS50.
