Activities and Layouts
Ted Hagos · Apress eBooks · 2018
Most apps will need one or more screens that they will use to communicate with the user. It is possible to write applications that don’t need a UI (e.g., apps that run in the background), but for the most part, when you create an application it will need a user interface, and for this reason, we need to understand activities. Building user interfaces is one of the fundamental skills that an Android programmer must have. In this chapter, we will take a look at how to build an app with a single and simple user interface. You have already created such an app back in Chapter 3, but we did not take a closer look at the activity component. These keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
