当电话进入空闲状态时,后台服务停止

我有一个粘性的后台服务,必须一直运行.基本上它跟踪时间,它是一个自定义时钟计时器.但是一旦设备进入空闲状态(当电话屏幕关闭时),定时器(后台服务)也会暂停.

即使屏幕关闭,我该怎么做才能使它始终保持运行？

    public class TimerService extends Service {
    private Context context;
    @Override
        public IBinder onBind(Intent intent) {
            Logger.LogI(TAG, "Service binding");
            return null;
        }

      @Override
        public void onCreate() {
            super.onCreate();
            context = getApplicationContext();
        }

     @Override
        public int onStartCommand(Intent intent, int flags, int startId) {
       return Service.START_STICKY;
        }
    }

因此,当设备进入睡眠模式时,有一些方法可以使服务不被杀死.我开始将我的服务作为附加通知的前台服务.我并不是说这是长期服务的更好方法.但当然这个解决方案可以进行更多优化.在睡眠模式下,此解决方案不会使服务进入暂停状态.

以下是整个服务代码:

public class TimerService extends Service {
    private ScheduledExecutorService scheduleTaskExecutor;
    private Context context;
    @Override
    public IBinder onBind(Intent intent) {
        Logger.LogI(TAG, "Service binding");
        return null;
    }

    @Override
    public void onCreate() {
        super.onCreate();
        context = getApplicationContext();
    }

    @Override
    public int onStartCommand(Intent intent, int flags, int startId) {
        setNotification();
        if (scheduleTaskExecutor == null) {
            scheduleTaskExecutor = Executors.newScheduledThreadPool(1);
            scheduleTaskExecutor.scheduleAtFixedRate(new mainTask(), 0, 1, TimeUnit.SECONDS);
        }
        return Service.START_STICKY;
    }

    public void setNotification() {
        PendingIntent contentIntent;
        contentIntent = PendingIntent.getActivity(this, 0,
            new Intent(this, Main_Activity.class), 0);

        NotificationManager mNotificationManager = (NotificationManager) this.getSystemService(Context.NOTIFICATION_SERVICE);
        NotificationCompat.Builder mBuilder =
            new NotificationCompat.Builder(this)
            .setSmallIcon(R.drawable.notification_icon)
            .setColor(this.getResources().getColor(R.color.action_bar_color))
            .setContentTitle("MainActivity")
            .setOngoing(true)
            .setAutoCancel(false)
            .setContentText("MyApp");
        mBuilder.setContentIntent(contentIntent);
        mNotificationManager.notify(NOTIFICATION_ID, mBuilder.build());

        Notification notification = mBuilder.build();
        startForeground(NOTIFICATION_ID, notification); //NOTIFICATION_ID is a random integer value which has to be unique in an app
    }
}
private class mainTask implements Runnable {

    public void run() {
        // 1 Second Timer
    }
}
