The Extensibility Framework relies on several configuration files.
By default, each application ships with a predefined set of configuration data, which is added to the project as a resource bundle. You can override the defaults by using external configuration files, which let you modify and enhance the look and feel of an app, add or remove UI elements and screens, modify data bindings and so on; that is, extend the app without having to recompile it.
Currently, you can distribute the configuration files from an SAP Mobile Platform Server in compressed form, which is called the Application Configuration Profile (ACP).
