Sending Apple Push Notifications with notnoop's java-apns library

If you need to send apple push notifications to your users, like we do in a secret project mentioned earlier this week, notnoop’s java-apns library is a good choice, because its really simple to use and saves you a lot of work.
(I presume that you already know how to get the Tokens of your users and already have a certificate for the push notifications, I only show you how easy the server part can be with this library. If you don’t know, read this first: Apple Push Service)
First you have to download the library (or add it in your maven dependencies):
The programming part isn’t that much so here’s how you do it:

public void pushMessage() {
		ApnsService service = null;
		try {
			// get the certificate
			InputStream certStream = this.getClass().getClassLoader().getResourceAsStream("your_certificate.p12");
			service = APNS.newService().withCert(certStream, "your_cert_password").withSandboxDestination().build();
			// or
			// service = APNS.newService().withCert(certStream,
			// "your_cert_password").withProductionDestination().build();
			// You have to delete the devices from you list that no longer
			//have the app installed, see method below
			// read your user list
			List<User> userList = userDao.readUsers();
			for (User user : userList) {
				try {
					// we had a daily update here, so we need to know how many
					//days the user hasn't started the app
					// so that we get the number of updates to display it as the badge.
					int days = (int) ((System.currentTimeMillis() - user.getLastUpdate()) / 1000 / 60 / 60 / 24);
					PayloadBuilder payloadBuilder = APNS.newPayload();
					payloadBuilder = payloadBuilder.badge(days).alertBody("some message you want to send here");
					// check if the message is too long (it won't be sent if it is)
					//and trim it if it is.
					if (payloadBuilder.isTooLong()) {
						payloadBuilder = payloadBuilder.shrinkBody();
					String payload =;
					String token = user.getToken();
					service.push(token, payload);
				} catch (Exception ex) {
					// some logging stuff
		} catch (Exception ex) {
			// more logging
		} finally {
			// check if the service was successfull initialized and stop it here, if it was
			if (service != null) {
	private void deleteInactiveDevices(ApnsService service) {
		// get the list of the devices that no longer have your app installed from apple
		//ignore the ="" after Date here, it's a bug...
		Map<String, Date> inactiveDevices = service.getInactiveDevices();
		for (String deviceToken : inactiveDevices.keySet()) {

Now wasn’t that an easy one this time?


  1. I used this code and in device ID i passed the right and wrong both gcm ID but how to check whether the code is working or not.

  2. To send a sound using APNS is really simple. The default sound can be added by changing the payLoadBuilder line to:
    payloadBuilder = payloadBuilder.badge(days).alertBody("some message you want to send here").sound("default");
    Custom sounds can also be used by specifying the name included in your app bundle. There are plenty of examples out there.
    Hope that helped.

  3. Hey, Please let me know how we can send emoji and sound in Java APNS code? Code snippet will be much useful.

  4. Could you please share your complete code ?
