Chapter 2. Java – First Contact

We now have a working Android development environment, and we have built and deployed our first app. It is obvious, however, that autogenerated code by Android Studio is not going to make the next top-selling app on Google Play. We need to explore this autogenerated code in order to understand Android and then begin 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 the first taste of using the Android UI designer
Write our first Java code
Learn a few core Java fundamentals and how they relate to Android

First, let's see how to find out whether things are going wrong.
