Add the ability to define a Preference Controller
in xml using the 'controller' tag.
This is useful for two reasons:
- It allows the controllers to be instantiated via
reflection for Slices and Dashboard fragment
- Removes the requirement that controllers be defined manually
in Fragments
In order to be instantiable, they must have a unified construction
following either:
ClassName(Context)
ClassName(Context, String)
Also added a robotest that verifies that all controllers defined
in XML follow the constructor schema, and extend
BasePreferenceController.
Test: robotests
