Sorry for this really late reply.......... What i get from your query is that it is related to how exactly the broadcast receiver working. So this what really happens when you register the receiver :- the receiver gets registered in some "file or registery file" of the Android OS. E.g you register a receiver for the EVENT that a SMS has been received. Now since you register the receiver for this ACTION_EVENT the Android OS checks its registry file to know which all receivers have to be notified. Each such broadcast receiver's object is instantiated in some order and the objects reference is held with the system itself. The broadcast receiver objects onReceive() method gets executed in which what ever the coder writes gets executed as longs as the execution is within 5 sec. Now as for the receiver when registered in any activity etc it lifecycle is governed by the activity's lifecycle i.e as long as the activity is alive the receiver will get executed if an EVENT occurs. When registered in Manifest the lifecycle is forever. Hope clears up some fog.
