Android broadcasts and services work together to modify controls on the interface

1. Create a class that inherits the server rewrite Onstartcommand. Different subroutines can be executed according to the parameters passed by intent, and a broadcast will be sent after execution is completed.

Declare the server in the declaration file add <server> tags in application, do not implicitly invoke

Intent Intent = new Intent ("broadcast identification");

2. Registering the broadcast in the main Activity

(1) First create an inner class to inherit Broadcastreceiver, and then set the interface according to the content of the Inten parameters received;

(2) define an inner class variable that you just created. Create a Intenfilter Intenfilter = new Intenfilter ("broadcast identification");

(3) Registerreceiver (internal class variable, intenfilter)
