Once inside an object, all the details can be seen, including the implemented interfaces, annotations, fields, inner classes and methods as well as the super class. Clicking on any of these items will move to a new page that shows a more in-depth view of this item. This page can tell you the modifiers on this object, its type, and if the object is a constant it will even tell you its value.
For certain apps the resources of the app can also be viewed. These are the materials that are used as icons, images, strings and even constants inside apps.
