Here we will make a little side project so we can play with everything we have learned so far. We will need to create a new project, just as we did in the previous chapter but we will not need a UI this time.

Instead, we will simply write some Java code and examine its effects by outputting the values of variables to the Android console, called logcat. We will see exactly how this works by building the simple project and examining the code and the console output:
