Android Learning Organization _ Server simple application. Music player

Android Learning Organization _ Service simple application. Music player

1. Because we need to use Service, we need to define it in the AndroidManifest. xml file.
<Service android: name = ". Music"> <! -- We will set a music. java file to implement -->
<Intent-filter>
<Action android: name = "com. edgar. PlayService. START_AUDIO_SERVICE"/> <! -- We will specify the name of the action that calls music. java.

<Category android: name = "Android. intent. category. default"/>
</Intent-filter>
</Service> remember to comment the code in the <application> label. Do not leave it outside. An error will be reported outside.

2. Then, put the music to be played in the res/raw folder.
