override this.Register : Java.Lang.Object * Java.Lang.Object -> boolParameters
- callbackcallbackInterface
- Object
The callback interface to be added to the list. Must not be null -- passing null here will cause a NullPointerException. Most services will want to check for null before calling this with an object given from a client, so that clients can't crash the service with bad data.
- cookie
- Object
Optional additional data to be associated with this interface.
Returns
Returns true if the interface was successfully added to the list.
Returns false if it was not added, either because #kill had
previously been called or the interface's process has gone away.
- Attributes
Remarks
Add a new interface to the list. This interface will remain in the list until a corresponding call to #unregister or its hosting process goes away. If the interface was already registered (determined by checking to see if the IInterface#asBinder callbackInterface.asBinder() object is already in the list), then it will be replaced with the new interface. Registrations are not counted; a single call to #unregister will remove an interface after any number calls to register it.
