|
* MessagingListener instance to be provided. It is expected that that listener
|
|
|

|
|
|
|
* command is to be executed, if the listener that was provided with the command
|
|
|
|
|
* is no longer registered the command is skipped. The design idea for the above
|
|
|
|
|
* is that when an Activity starts it registers as a listener. When it is paused
|
|
|
|
|
* it removes itself. Thus, any commands that that activity submitted are
|
|
|
|
|
* removed from the queue once the activity is no longer active.
