Dynamic register broadcast receiver and dynamic broadcast Receiver

Dynamic register broadcast receiver and dynamic broadcast Receiver
Dynamically register broadcast recipients

 

This code serves the same purpose as the code below the static register broadcast receiver:

It is used to listen to call applications.

 

Dynamic Registration does not work normally when the application is opened for the second time.

Applicable scenarios:

Static registration: Suitable for broadcasts to be listened to after the program ends. For example, ipdialing.

Dynamic Registration: Suitable for broadcasts that do not be listened to after the program ends. For example, if the data displayed on the interface is updated by the broadcast receiver, it is unnecessary to execute the broadcast listener when the interface is closed.
