Question

I have a grails app, and I am using the java-apns 0.1.5 jar! I have a device key, which already uninstall my app from it, so my question is, should I receive same feedback from the API saying that device is not enable anymore?
My code is the following:

apnsService = APNS.newService()
        .withCert(pathToCertificate, password)
        .withFeedbackDestination("feedback.sandbox.push.apple.com",2196)
        .withSandboxDestination()
        .build();

apnsService.start();

Map<String, Date> inactiveDevices = apnsService.getInactiveDevices();
log.debug inactiveDevices

.....

the think is that, the variable inactiveDevices is always empty! why? if I uninstall the app from the device?! am I missing some think in the client(device) side?

If you are using the Sandbox destination, the feedback service may not
report info correctly. This is a known bug with a known workaround,
check the mailing list thread

The problem comes from the “Sandbox” APNs Feedback server, probably a
bug. Here is the solution if anyone has the same problem:

Create a dummy app id in the program portal, enable development push
notifications on it Create and download the associated provisioning
profile Create a new xcode project, and invoke the
registerForRemoteNotificationTypes method on start. Install the dummy
app on your device. At this point, you should have two DEVELOPMENT
apps running on your device: the original app and the dummy app. Both
should be registered to receive push notifications. Uninstall the
original app, and try to send a push notification to that app. Invoke
the feedback service, and you should receive data back.

To resume, the Sandbox Feedbacks server needs TWO DEVELOPMENT Apps
registered on the SAME iPhone to work. This manipulation is not
necessary for the production phase as the “Production” APNs Feedback
server works fine.

I would recommend just switching to test feedback with the production servers.
Please either test with the production servers or use the workaround.
