Broadcastreceiver (broadcast receiver) is one of the four major components of Android. The following is a detailed description of the use of the broadcast receiver component.
The following is an overview of Broadcastreceiver in Android Doc:

This section describes how to create a broadcast, how to send an unordered broadcast and ordered broadcast, and how to listen to text messages and outgoing calls. (when we send text messages and make phone calls, the system sends a broadcast, we can intercept this broadcast to listen for text messages and listen for outgoing calls ).
Define broadcast Receiver
1. Define the class to inherit BroadcastReceiver and override the onReceive method.
2. Afte
