A broadcast receiver (receiver) is an Android component which allows you to register for system or application events. All registered receivers for an event are notified by the Android runtime once this event happens.
Because services aren't directly visible, Android considers them less important than activities, so they'll be the first to be killed when your phone needs more memory. Broadcast receivers are the third kind of component. Like services, they only exist in the background and don't interact with you directly.
Broadcast Receiver Overview. A broadcast receiver is an Android component that allows an application to respond to messages (an Android Intent ) that are broadcast by the Android operating system or by an application.
Android BroadcastReceiver is a dormant component of android that listens to system-wide broadcast events or intents. When any of these events occur it brings the application into action by either creating a status bar notification or performing a task.
Service: If you want to do something in background , this will be running always in background even if the application closed. You can create this in separate process and also you can give your service to other app if you want. Downloading any content or Music is good example
Broadcast Reciever: Usually system will send some info which can be recieved by your app if you would wish to ,by registering. And you can do something what you want when that thing happens by using onReceive method. Example is the system will send BroadcastReceiver when new sms arrives or Booting done
