Class Push

java.lang.Object

javapns.Push

public class Push
extends Object

Main class for easily interacting with the Apple Push Notification System

This is the best starting point for pushing simple or custom notifications, or for contacting the Feedback Service to cleanup your list of devices.

The JavaPNS library also includes more advanced options such as multithreaded transmission, special payloads, and more. See the library's documentation at http://code.google.com/p/javapns/ for more information.

password - the keystore's password.

                                    KeystoreException

Retrieve a list of devices that should be removed from future notification lists.

Devices in this list are ones that you previously tried to push a notification to, but to which Apple could not actually deliver because the device user has either opted out of notifications, has uninstalled your application, or some other conditions.

Important: Apple's Feedback Service always resets its list of inactive devices after each time you contact it. Calling this method twice will not return the same list of devices!

Please be aware that Apple does not specify precisely when a device will be listed by the Feedback Service. More specifically, it is unlikely that the device will be listed immediately if you uninstall the application during testing. It might get listed after some number of notifications couldn't reach it, or some amount of time has elapsed, or a combination of both.

Further more, if you are using Apple's sandbox servers, the Feedback Service will probably not list your device if you uninstalled your app and it was the last one on your device that was configured to receive notifications from the sandbox. See the library's wiki for more information.

Parameters:

keystore - a keystore containing your private key and the certificate signed by Apple (File, InputStream, byte[], KeyStore or String for a file path)

password - the keystore's password.

production - true to use Apple's production servers, false to use the sandbox servers.

Returns:

a list of devices that are inactive.

Throws:

KeystoreException - thrown if an error occurs when loading the keystore

CommunicationException - thrown if an unrecoverable error occurs while trying to communicate with Apple servers
