Android phones and other devices are all about communicating with the world. This chapter covers apps that call, text, e-mail, and even tweet. In general, we'll build practical apps that communicate in some form or the other, using the basics learned in previous chapters.
In this chapter, we'll learn:
Building apps that look up phone numbers and make calls for us, and do other neat things related to phone calls
How to use texting and keep in touch with our friends
Constructing apps that send e-mails
Apps for social communication
Good, we're getting into it. Now that we can drag together blocks that do things (quite literally the way in which we program using Google App Inventor), let's explore communications capability in our apps.
