Chapter 2. First Contact – Java, XML, and the UI Designer

At this stage, we have a working Android development environment and we have built and deployed our first app. It is obvious, however, that code auto-generated by Android Studio is not going to make the next top-selling app on the Google Play Store. We need to explore this auto-generated code so that we can begin to understand Android and then learn how to build on this useful template. With this aim in mind, in this chapter, we will do the following:

See how to get technical feedback from our apps
Examine the Java code and UI XML code from our first app
Get our first taste of using the Android User Interface (UI) designer
Write our first Java code
Learn some core Java fundamentals and how they relate to Android

First, let's see how to get feedback from our apps.
