Glide is a fast and efficient open source media management framework for Android that wraps media decoding, memory and disk caching, and resource pooling into a simple and easy to use interface.
Glide supports fetching, decoding, and displaying video stills, images, and animated GIFs. Glide includes a flexible api that allows developers to plug in to almost any network stack. By default Glide uses a custom HttpUrlConnection based stack, but also includes utility libraries plug in to Google's Volley project or Square's OkHttp library instead.
Glide's primary focus is on making scrolling any kind of a list of images as smooth and fast as possible, but Glide is also effective for almost any case where you need to fetch, resize, and display a remote image.
RoboGuice is a framework that brings the simplicity and ease of Dependency Injection to Android, using Google's own Guice library. If you've ever used Spring (the #1 enterprise framework on Java, now more popular than J2EE itself) or Guice, you already know how convenient this style of programming can be.
