event OnReceiveNotificationEvent occurs two times in a row

[Lena]

Hi.
I found information how to send native push without Kinvey (but in Russian from http://fire-monkey.ru):

http://blog.rzaripov.kz/2017/02/firebas ... ios-2.html
Everyone who writes a Delphi event OnReceiveNotificationEvent happens once.
When I send push:

Code: Select all

http://mysite.com/pushTest/api.php?method=sendPush&title=My title&text=Custom text

in my C++ code event OnReceiveNotificationEvent occurs two times in a row.
Is this the next mistake idera or my?

Code: Select all

//h file
#include <System.Net.HttpClient.hpp>
#include <System.JSON.hpp>
#include <System.PushNotification.hpp>

private:	// User declarations
	String FDeviceID;
	String FDeviceToken;

	TPushService * FPushService;
	TPushServiceConnection * FPushServiceConnection;

	void __fastcall OnReceiveNotificationEvent(TObject *Sender, TPushServiceNotification* const ANotification);
	void __fastcall OnServiceConnectionChange(TObject *Sender, TPushService::TChanges AChange);
	void __fastcall PushServiceRegister();
   	void __fastcall RegisterDevice();
