No, RoboGuice isn’t the latest and greatest energy drink marketed to developers — it’s a framework that uses the Google Guice library to streamline dependency injection. Dependency injection handles the initializing of variables at the right time so that you don’t have to. This concept cuts down the amount of code you have to write overall, and it makes maintaining your application a breeze.
