LocalBroadcastReceiver is the same as BroadcastReceiver in Android. So if you know how to use BroadcastReceiver then you have got this. The code is almost similar.

LocalBroadcastManager localBroadcastManager = LocalBroadcastManager.getInstance(this);

2) For registering BroadcastReceiver


registerReceiver(new YourReceiver(),new IntentFilter("YourAction"));


localBroadcastManager.registerReceiver(new YourReceiver(),new IntentFilter("YourAction"));

3) For sending a broadcast message





4) For unregistering BroadcastReceiver





And that's it.
