/**
 * 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()

    // Standard Guice injection of Plain Old Java Objects (POJOs)
    // 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.
