Learning MIT App Inventor: A Hands-On Guide to Building Your Own Android Apps

Modeling Things with Data

Lists are a method for organizing sets of data. You might write that data right into the blocks of the app, and it will never change. Alternatively, the user might input that data while the app is running. That data might even be a series of sensor readings, such as those from the GPS, or a list of restaurants the app pulled from the Internet. Data can take many forms, whether a list of contacts, a collection of GPS coordinates, or a bank of questions (we use the latter with the Android Quiz app later in this chapter).

Good use of data requires not just getting it, but also learning how it can tell a story or be part of a larger purpose. Next, we look at how MIT App Inventor specifically can empower you to do this. ...
