Real implementation of the android plugin
Real implementation of the android plugin

Assumptions:
- Since the input name has to be consistent between android and iOS, we assume
  that the screenName is the class name of the activity.
- But then we need to figure out the package that it is in. We assume that it
  is in the same package as the cordova activity.

The rest of the implementation is pretty straightforward - we simply:
- compute the fully qualified class name of the activity,
- find its class,
- and launch an intent using the class
