Open App Android

Description of Open App Android

Open App Android is an app created to allow users and particularly other Android developers to browse the internal structure of your favourite apps and discover how they work. You can easily select from any app that you've installed as well as the pre-installed system apps and load any object (in the Java sense) that's used in the app to view its details. This is known as Type Introspection and in future updates, full reflection capabilities will be added so that any object can be instantiated and manipulated completely inside the app.
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.
