Response time from APNS

[Saranyu Ngaosri]

Hello everyone, I have a question about response time from APNS, 

I am trying to send VOIP notification with pushy and this lib works fine But it takes about 20-23 seconds to get the response.

Before, I  tried to send notifications by CURL and got quickly response.

And this is my code

public String sendNotification() throws Exception {

String respon_result = "";

File cert_file = new File("/Certificates2.p12");

final ApnsClient apnsClient = new ApnsClientBuilder().setApnsServer(ApnsClientBuilder.DEVELOPMENT_APNS_HOST)

.setClientCredentials(cert_file, "*******").build();

final ApnsPayloadBuilder payloadBuilder = new SimpleApnsPayloadBuilder();

payloadBuilder.setAlertTitle("Test Voip");

payloadBuilder.setAlertBody("Test Voip by pushy");

payloadBuilder.setBadgeNumber(1);

payloadBuilder.setSound("default");

payloadBuilder.setCategoryName("call");

payloadBuilder.setContentAvailable(true);

final String payload = payloadBuilder.build();

final String token = "******";

final String topic = "";

System.out.println("Payload: " + payload );

final SimpleApnsPushNotification pushNotification = new SimpleApnsPushNotification(token, topic, payload, null,

null, PushType.VOIP);

final PushNotificationFuture<SimpleApnsPushNotification, PushNotificationResponse<SimpleApnsPushNotification>> sendNotificationFuture = apnsClient

.sendNotification(pushNotification);

try {

final PushNotificationResponse<SimpleApnsPushNotification> pushNotificationResponse = sendNotificationFuture

.get();

if (pushNotificationResponse.isAccepted()) {

System.out.println("Push notification accepted by APNs gateway.");

System.out.println("Push notification APNS-ID: " + pushNotificationResponse.getApnsId().toString());

respon_result = "Push notificationaccepted by APNs gateway." + "\n" + "Push notification APNS-ID: "

+ pushNotificationResponse.getApnsId().toString();

} else {s

System.out.println(

"Notification rejected by the APNs gateway: " + pushNotificationResponse.getRejectionReason());

pushNotificationResponse.getTokenInvalidationTimestamp().ifPresent(timestamp -> {

System.out.println("\t…and the token is invalid as of " + timestamp);

});

respon_result = "Notification rejected by the APNs gateway: "

+ pushNotificationResponse.getRejectionReason();

}

} catch (final ExecutionException e) {

System.err.println("Failed to send push notification.");

e.printStackTrace();

respon_result = "Failed to send push notification.";

} finally {

return respon_result;

}

}
