Public class music extends Service {@ Overridepublic IBinder onBind (Intent intent) {System. out. println ("service bound successfully"); // when the service is bound successfully, call the onbind method to return an ibinder object return new MyBinder ();} public class MyBinder extends Binder {public void callchange (String name) {// call the song method classmusc (name) ;}@ Overridepublic void onCreate () {System. out. println ("service enabled"); super. onCreate ();} public void classmusc (String Singname) {Toast. makeText (getApplicationContext (), "song is" + Singname, 1 ). show () ;}@ Overridepublic void onDestroy () {System. out. println ("service destruction"); super. onDestroy ();}}
