Broadcasts in android

 Broadcasts listens to any type of event like touch or walk or sms recieve and then do something on recieving the broadcast .via OnRecieve method   . LIKE FOR EXAMPLE

If we want to do something when an sms is recieved in mobile then first declaring broadcast and intentfilter inside the manifest then creating a class extending broadcastReciever . we can do what we want in OnResponse method.
