Delphi Android Oreo: How to start service in foreground?

I need to start a service for Android Oreo in foreground but I can't find an example how to do this in Delphi 10.3 for the app and for the service.

I found hints that I have to use startForegroundService in the app and startForeground in the service but I do not know how and where to use these calls.

In the app I start my service with

  FService := TLocalServiceConnection.Create;
  FService.StartService('MySvc');

In the service I execute the following statement:

function TDM.AndroidServiceStartCommand(const Sender: TObject; const Intent: JIntent; Flags, StartId: Integer): Integer;
begin
  Result := TJService.JavaClass.START_STICKY;
end;

Example of how to start and stop a service in the foreground:

uses
  Androidapi.JNI.Support, Androidapi.Helpers;

procedure TServiceModule.StartForeground;
var
  LBuilder: JNotificationCompat_Builder;
begin
  LBuilder := TJNotificationCompat_Builder.JavaClass.init(TAndroidHelper.Context);
  LBuilder.setAutoCancel(True);
  LBuilder.setContentTitle(StrToJCharSequence('Title'));
  LBuilder.setContentText(StrToJCharSequence('Text'));
  LBuilder.setSmallIcon(TAndroidHelper.Context.getApplicationInfo.icon);
  LBuilder.setTicker(StrToJCharSequence('Caption'));
  // 1413 is just a number picked at random
  TJService.Wrap(System.JavaContext).startForeground(1413, LBuilder.build);
end;

procedure TServiceModule.StopForeground;
begin
  TJService.Wrap(System.JavaContext).stopForeground(True);
end;
