You don't have to register a BroadcastRecevier when you start a Service. That is, even if you don't register a BroadcastReceiver, our Service will work as expected. There is no must have dependency between the two.

As explained by Gridtestmail, a Service is a process you want to run in the background, without having an interface to the user.

A BroadcastReceiver is registered, when you want to be notified about certain events happening - for example, discovering a new bluetooth device or receiving an incoming call. If you register a BroadcastReceiver for receiving incoming calls , then your Receiver's onReceive() method is called whenever there is an incoming all, so you can process it. Similarly, for other event detection stuff.

I hope the concept is clear to you now.

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

Example : Service and BroadcastReceiver
