In this chapter, we will take a roller coaster ride through all the Android topics that you need to learn in order to get started with Java. It won't just be theoretical though. We will be designing a user interface (UI) of a game menu and we will see and edit our first Java code as well.

In addition, we will see how we can run our apps in either an Android emulator on our PC/Mac or on a real Android device if we have one.

Some of what we will cover in this chapter will be the tip of the iceberg. That is, there is a lot more below the surface to some of the topics we discuss than would be appropriate for the second chapter of a learning Java book. Sometimes, we might need to take a bit of information on faith.

This will then enable us to actually design and run our very own Android app by the end of this chapter. Then we can start learning Java for real at the beginning of the next chapter.

If this chapter seems a little tough, then don't worry; keep going...
