Android realizes simple music playback through service

Android music playback effect, simple service on.

Here we will use one of the four components of Android: service

Note: service is one of the main components and needs to be registered.

What is service?

1: "Service" means "service". Like services on windows, services run in the background and undertake quiet and unnoticed work.

2: Service runs in the background. It is an invisible program without interface.

3: Service can be used in many applications. For example, when the user starts other activities when playing multimedia, the program should continue to play in the background; For example, detect the changes of files on SD card; Or record the change of the user's geographic information location in the background; Or start a service to run and listen for certain actions all the time, and so on.

Here is the source code:

MainActivity

Mybroadcastreceiver class (broadcast receiver):

Playingmusicservices class:

Finally, don't forget to register the service in the manifest configuration file:

Create a new raw folder under res and put the downloaded MP3 files into. The songs here are my own, and the songs here are birds.mp3.

Run without error under Android studio.
