首先

繫結Servie服務
  private KWMusicService mKWService;
 private void bindMessageRouterService() {
        Intent intent = new Intent("action"); //action 為要繫結的service的action名字 
        // for android 5.0 and above
        if (ExternalAppManager.getExplicitIntent(mContext, intent) != null) {
            intent = ExternalAppManager.getExplicitIntent(mContext, intent);
        }
        mContext.bindService(intent, mConnection, Context.BIND_AUTO_CREATE);
    }

    private ServiceConnection mConnection = new ServiceConnection() {

        @Override
        public void onServiceConnected(ComponentName name, IBinder service) {

            mKWService = ((KWMusicService.LocalBinder) service).getService();
           //to do
        }

        @Override
        public void onServiceDisconnected(ComponentName arg0) {
            rebindMessageRouterService();
        }
    };
 

   //Service 例項物件 mKWService

 private void rebindMessageRouterService() { if (mKWService == null) { LogUtil.d(TAG, "rebindMessageRouterService"); bindMessageRouterService(); } }

service 要在manifest中申明下action名字 eg:
    <service
            android:name=".manager.KWMusicService"
            android:exported="true" >
            <intent-filter>
                <action android:name="com.spt.carengine.aiosvoice.kwservice" />
            </intent-filter>
        </service> 

Service端 返回一個binder

   @Override
    public IBinder onBind(Intent intent) {
        LogUtil.d(TAG, "--onBind--");
        return mBinder;
    }

    private final IBinder mBinder = new LocalBinder();

    public class LocalBinder extends Binder {
        public KWMusicService getService() {
            return KWMusicService.this;
        }
    }
