我想实现一个BroadcastReceiver开机启动Service，并在service中启动Notification的功能，但是不能正常运行。这是我的代码，大佬们能不能帮我看看为什么：



public class UpdateService extends IntentService {

    public UpdateService() {

        super("UpdateService");

        System.out.println( "开机自动服务自动启动.....");

    }

    @Override

    protected void onHandleIntent(Intent intent) {

        getNotification();

    }

    @Override

    public void onDestroy(){

        super.onDestroy();

        Log.d("Demo","onDestroy 已执行");

    }

    public void getNotification() {

        NotificationManager manager = (NotificationManager) getSystemService(Service.NOTIFICATION_SERVICE);

        Notification notification = new Notification();

        notification.tickerText = "来消息了";

        notification.icon = R.mipmap.image2;

        notification.flags = Notification.FLAG_AUTO_CANCEL;

        notification.defaults =Notification.DEFAULT_VIBRATE;

        long when = System.currentTimeMillis();

        notification.when = when;

        Intent intent = new Intent(getApplication(), FoodDetailed.class);

        PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent, Intent.FILL_IN_ACTION);

        Notification.Builder builder = new Notification.Builder(this);

        builder.setContentTitle("Bmob Test");

        builder.setContentText("IM start up");

        builder.setSmallIcon(R.drawable.img1);

        //Notification builder = new Notification.Builder(this).setTicker("显示于屏幕顶端状态栏的文本").setSmallIcon(R.mipmap .image2).build();

        manager.notify(0, notification);

    }

}



public class DeviceStartedListener extends BroadcastReceiver {

    public DeviceStartedListener() {

    }





    @Override

    public void onReceive(Context context, Intent intent) {

        Log.e("TAG", "开机自动服务自动启动.....");

        //后边的XXX.class就是要启动的服务

       Intent serviceIntent = new Intent(context, UpdateService.class);

        context.startService(serviceIntent);



        System.out.println( "开机自动服务自动启动.....");

    }

}
