Android service call OnDestroy immediately when i start the service in sleep mode

Question

I use a BroadcastReceiverTo:

Wake up the phone
Playing sound and vibration in a service
Show an Activity

Every things work well when i test it while the phone is not in Sleep mode

BUT

When the phone is in Sleep mode (phone is locked and the screen is off), the screen goes ON and the Activity is displayed well but Vibration Service goes to OnDestroy immediately after onStartCommand!

My BroadcastReceiver:

public class TimerTimeoutBroadcastReceiver extends BroadcastReceiver {

    public void onReceive(Context context, Intent intent) {

        WakeLockManager.acquireWakeLock(context);

        Intent closeDialogs = new Intent(Intent.ACTION_CLOSE_SYSTEM_DIALOGS);
        context.sendBroadcast(closeDialogs);

        // Open OffAlarm Activity
        StartAlarmOffActivity(context);

        //StartVibrationService
        StartVibrationService(context);
    }

    private void StartAlarmOffActivity(Context context) {
        Intent alarmeActivity = new Intent(context, AlarmScreenOffActivity.class);
        alarmeActivity.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        context.startActivity(alarmeActivity);
    }

    private void StartVibrationService(Context context) {
        Intent playAlarm = new Intent(context, AlarmSoundVibrationService.class);
        context.startService(playAlarm);
    }
}

In Vibration Service:

@Override
public int onStartCommand(Intent intent, int flags, int startId) {
    if (intent == null) {
        stopSelf();
        return START_NOT_STICKY;
    }
    play();
    return START_STICKY;
}

@Override
public void onDestroy() {
    super.onDestroy();
    stop();


    WakeLockManager.releaseWakeLock();
}

In WakeLockManager:

PowerManager pm = (PowerManager) context.getSystemService(Context.POWER_SERVICE);
mWakeLock = pm.newWakeLock(PowerManager.SCREEN_BRIGHT_WAKE_LOCK | PowerManager.ON_AFTER_RELEASE , "My Tag");

My questions:

How can i prevent call OnDestroy Immediately when i start my service in sleep mode?
Should i use a notification to keep this service alive?

Edit 1

I tried to take the service as a foreground service by a notification:

private void showNotification() {

    CharSequence text = getText(R.string.alarm_vibration_service_started);

    // The PendingIntent to launch our activity if the user selects this notification
    PendingIntent contentIntent = PendingIntent.getActivity(this, 0,
            new Intent(this, AlarmScreenOffActivity.class), 0);

    // Set the info for the views that show in the notification panel.
    Notification notification = null;

    if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.JELLY_BEAN) {

        notification = new Notification.Builder(this)
                .setSmallIcon(R.mipmap.ic_launcher)  // the status icon
                .setTicker(text)  // the status text
                .setWhen(System.currentTimeMillis())  // the time stamp
                .setContentTitle(getText(R.string.alarm_vibration_service_label)+" "+mTimerTitle)  // the label of the entry
                .setContentText(text)  // the contents of the entry
                .setContentIntent(contentIntent)  // The intent to send when the entry is clicked
                .build();
    }

    // Send the notification.
    startForeground(Alarm_Vibration_SERVICE_Id,  notification);
}

Now i call showNotification in onStartCommand but it could not helped me!

I'm success when used i use a Thread.Sleep(10000) in onStartCommand after Play() and i have vibration on my phone for 10 second.

Codes:

private void play() {
    stop();
    mVibrator.vibrate(sVibratePattern, 0);

    enableTimeOut();

    mPlaying = true;
}

public void stop() {
    if (mPlaying) {
        mPlaying = false;
        mVibrator.cancel();
    }
    disableTimeOut();
}

private void enableTimeOut() {
    mHandler.sendMessageDelayed(
            mHandler.obtainMessage(TIMEOUT, true),
            1000 * ALARM_TIMEOUT_SECONDS);
}

Also i tested above codes in some cases. The result (Vibration for 10 seconds) was:

Failed: Sleep-Mode => An Activity with a countdown ----start----> TimerTimeoutBroadcastReceiver

Failed: Sleep-Mode => A Service ----start----> TimerTimeoutBroadcastReceiver

Failed: Normal-Mode => A Service ----start----> TimerTimeoutBroadcastReceiver

Success: Normal-Mode => An Activity with a countdown ----start----> TimerTimeoutBroadcastReceiver

Finally I want start TimerTimeoutBroadcastReceiver from a Service in my APP but this problem confused me!

The problem solved! Really my service (and also the notification) has worked correctly but i has this codes in onPause of the Activity:

protected void onPause() {
    Intent playAlarm = new Intent(this, AlarmVibrationService.class);
    stopService(playAlarm);
    super.onPause();
}

It (onPause) happens right after my Activity opens in sleep-mode! I don't now why it happens but it cause stopping the service. Now i removed above code and the problem solved...

Android service call OnDestroy immediately when i start the service in sleep mode
