About sticky intent ACTION_BATTERY_CHANGED

Question

I'm using this code:

Intent i = getApplicationContext().registerReceiver(null, new IntentFilter(Intent.ACTION_BATTERY_CHANGED));

and as far as I understand i should be null if ACTION_BATTERY_CHANGED didn't occur, but it is never null and always returns me the same data. It worked fine when I used a broadcast receiver. Do I need to delete the Intent after receiving it?

As soon as you register sticky intents will always deliver you last broadcasted data. So that is the reason you are always recieving data

so I need to comapre the battery level for example to see if a new Intent was bradcasted? – user1566228 Aug 13 '12 at 14:10
this will only happen the first time you register. Later on you will recieve as soon as broadcast is done – nandeesh Aug 13 '12 at 17:59
but I dont use a Receiver. I want to check, lets say, every 60 seconds if a occured since the last check. – user1566228 Aug 13 '12 at 19:48
why would you want that when as soon as battery is changed you get a callback. – nandeesh Aug 13 '12 at 19:59

it depends on what your app does? what is the use case? – nandeesh Aug 14 '12 at 09:51

Sticky=property of adhering result=which intent adhered with os called sticky intent

Normally you send broadcast a receiver using sendBroadcast(Intent) But When you are calling this method sendStickyBroadcast(Intent) it means that A broadcast Intent can be specified to be sticky in which case it will be retained by the system after it has been sent. But by default Intent.ACTION_BATTERY_CHANGED intent is sticky.
