/**
* This activity uses an AstroboyRemoteControl to control Astroboy remotely!
*
* What you'll learn in this class:
* - How to use @InjectView as a typesafe version of findViewById()
* - How to inject plain old java objects as well (POJOs)
* - When injection happens
* - Some basics about injection, including when injection results in a call to
* an object's default constructor, versus when it does something "special"
* like call getSystemService()

// Guice will find or create the appropriate instance of AstroboyRemoteControl for us
// Since we haven't specified a special binding for AstroboyRemoteControl, Guice
// will create a new instance for us using AstroboyRemoteControl's default constructor.
// Contrast this with Vibrator, which is an Android service that is pre-bound by RoboGuice.
// Injecting a Vibrator will return a new instance of a Vibrator obtained by calling
// context.getSystemService(VIBRATOR_SERVICE). This is configured in DefaultRoboModule, which is
// used by default to configure every RoboGuice injector.
