Beginning Android 4 Games Development

AndroidInput and AccelerometerHandler

Using a couple of convenient methods, the Input interface we designed in Chapter 3 grants us access to the accelerometer, the touchscreen, and the keyboard in polling and event modes. The idea of putting all the code for an implementation of that interface into a single file is a bit nasty, so we outsource all the input event handling to handler classes. The Input implementation will use those handlers to pretend that it is actually performing all the work.

AccelerometerHandler: Which Side Is Up?

Let's start with the easiest of all handlers, the AccelerometerHandler. Listing 5–5 shows you its code.
