# Introduction
Broadcast receivers in Android are a pub-sub-based messaging system that can be used by applications to broadcast and receive important announcements. Any application can broadcast a message, and the Android framework will take care of sending the message to all registered subscribers. In addition to applications, several broadcast messages are published by the Android operating system. These broadcasts can be related to boot-up, battery level, or connectivity status, among other things.

Let’s get right to it and learn how to send and receive broadcast messages.


# Send broadcasts

Android provides a mechanism for apps to broadcast custom messages. Let's learn how to send broadcast messages using the `sendBroadcast` method. The `sendBroadcast` event transmits messages to all registered subscribers at once. We can restrict the broadcast to our application using  `LocalBroadcastManager.sendBroadcast`. 

Let’s see how to send out a custom broadcast message with a button click. Assume that our application wants to send out a broadcast to all registered subscribers whenever a new video is available.

Learn about broadcast receivers and how they can be used to announce or receive events.
