Background service stops as soon as the app closed

I am creating a messaging app for that I need a service to receive message even when the app is closed or open, I have a broadcast receiver to receive SMS and I created a service class and started in my mainActivity as

Intent mIntent=new Intent(this,BackgroundService.class);
startService(mIntent);

and in the manifest, I added the service as 

 <service android:name=".BackgroundService"
            android:enabled="true"/>

broadcastReceiver class

@Override
public void onReceive(Context context, Intent intent) {


    Bundle intentExtras = intent.getExtras();
    if (intentExtras != null) {

        Object[] sms = (Object[]) intentExtras.get(SMS_BUNDLE);
        String smsMessageStr = "";
        for (int i = 0; i < sms.length; ++i) {
            SmsMessage smsMessage = SmsMessage.createFromPdu((byte[]) 
sms[i]);

            smsBody = smsMessage.getMessageBody().toString();
            address = smsMessage.getOriginatingAddress();


            smsMessageStr += "SMS FROM :" + address + "\n";
            smsMessageStr += "Message :" + smsBody + "\n";
        }
            Toast.makeText(context, smsMessageStr, 
Toast.LENGTH_LONG).show();

backgroundService.java

public class BackgroundService extends Service{

private SmsBroadcastReceiver mSmsBroadcastReceiver;
private IntentFilter mIntentFilter;
private static final int NOTIFICATION_ID = 999;


@Override
public int onStartCommand(Intent intent, int flags, int startId) {

    mSmsBroadcastReceiver=new SmsBroadcastReceiver();
    mIntentFilter=new IntentFilter();
    mIntentFilter.addAction("android.provider.Telephony.SMS_RECEIVED");
    mIntentFilter.setPriority(999);
    registerReceiver(mSmsBroadcastReceiver,mIntentFilter);

    return START_STICKY;
}

@Nullable
@Override
public IBinder onBind(Intent intent) {
    return null;
}
}

I HAVE TRIED foreground service also as

 Notification notification = new NotificationCompat.Builder(this)
            .setContentTitle("TutorialsFace Music Player")
            .setTicker("TutorialsFace Music Player")
            .setContentText("My song")
            .setSmallIcon(R.mipmap.ic_launcher)
            .build();
        startForeground(NOTIFICATION_ID,
            notification);

but as soon as I close my app from recent apps the service also gets stopped and when I restart my app its the service gets starting

how can I make my service to live long even when the app is closed. Because my app is SMS based one so without service I cant receive the messages while my app is closed, any help will be appreciated, thanks in advance.

Yes the service is working in the same thread with the app you can override the method onDestroy to launch your service again with his own thread.

@Override
public void onDestroy() {
    super.onDestroy();
    getApplicationContext().startService(new Intent(getApplicationContext(), BackgroundService.class));
}
