android service 之startService(...)

1,创建一个MusicPlayService继承Service,并重写onCreat(）方法和onStartCommand(...)方法

publicclassMusicPlayServiceextendsService{@OverridepublicvoidonCreate(){//TODOAuto-generatedmethodstubLog.e(TAG,"MusicSericeonCreate()");//musicplay=BackgroundMusicPlay.getBackgroundMusicPlay(this);super.onCreate();}@OverridepublicintonStartCommand(Intentintent,intflags,intstartId){Log.e(TAG,"MusicSerice--->onStartCommand()");playMusic();returnsuper.onStartCommand(intent,flags,startId);}publicvoidplayMusic(){musicplay.musicPlay();//mp=MediaPlayer.create(getApplicationContext(),R.raw.newgalactic);//mp.setLooping(true);//mp.start();}}

注意：由于onStart(...)方法在level 2.0之后已经失效，所以2.0之后用onStartCommand代替，具体请查看API文档http://tool.oschina.net/apidocs/apidoc?api=android/reference

2，在activity中通过startService(...)调用服务

Intentintent2=newIntent(ShorMusicPlay.this,MusicPlayService.class);startService(intent2);//启动服务stopService(intent2);//结束服务
