We can use intent to start a component, or use the sendbroadcast () method to initiate a system-level event broadcast to transmit m

Explanation of Intent in Android (2) Introduction to using Intent to Broadcast events and Broadcast Receiver
The first article explains how to use Intent to start new application components. However, they can also use the sendBroadcast method to anonymously broadcast messages between components.
