Implementing a 

BlackBerry Dynamics

 event listener

The 

Application

 object manages the global app state of an app.

Many of the sample apps installed with the 

BlackBerry Dynamics

 Bindings for 

Xamarin

 implement the event handling lifecycle. There are several key parts to implementing the life cycle of events. You have your choice of approach, one of which is presented here.

Specify GDappID and Version.
Implement the IGDAppEventListener and IGDStateListener interfaces.
Special-case the 
OnNotAuthorized
 events.
On authorization, relying on 
GDErrorNone
, start the app UI.
Assign IGDEventListener and IGDStateListener implementations to the Android class.
Initialize your Activity for use with the BlackBerry Dynamics runtime.
