Module Module1

Sub Main()

    Console.WriteLine("Start notification : ")

    Dim push As New PushBroker()

    AddHandler push.OnDeviceSubscriptionExpired, AddressOf DeviceSubscriptionChanged
    AddHandler push.OnChannelException, AddressOf ChannelException
    AddHandler push.OnServiceException, AddressOf ServiceException

    AddHandler push.OnChannelDestroyed, AddressOf ChannelDestroyed

    push.RegisterGcmService(New GcmPushChannelSettings("AIzaSyCcyNj2Q8bHJqJ-gFR6N3CFtM_VJpv9lIE"))
    push.QueueNotification(New GcmNotification().ForDeviceRegistrationId("APA91bGPD7eT7_MEqnL5D23BxihL3-4JkpFGpKy_2A2MNIJHFyEqhSM0iFVMRortNg_394VjsXqyuP0vbPbTQcWL-3ab_4mp-rUn4ypfkntqXfgurBeXOc6M5j25ewuclXuhezhV5yULQzpiJWoOlhYFn28Yx8iJRTA5jup4lKYBo7uVObSsLzs").WithJson("{""alert"":""Hello World2!"",""badge"":6,""sound"":""sound.caf""}"))

    Console.WriteLine("Waiting for Queue to Finish...")

    'Stop and wait for the queues to drains
    push.StopAllServices(True)

    Console.WriteLine("Queue Finished, press return to exit...")
    Console.ReadLine()
End Sub

Sub DeviceSubscriptionChanged(sender As Object, oldSubscriptionId As String, newSubscriptionId As String, notification As INotification)
    'Currently this event will only ever happen for Android GCM
    Console.WriteLine("Device Registration Changed:  Old-> " & oldSubscriptionId & "  New-> " & newSubscriptionId & " -> " & Convert.ToString(notification))
End Sub

Sub NotificationSent(sender As Object, notification As INotification)

i have a good api key and i get my registration id with a phonegap plugin. I have already test my api key and my registration id with a little npm module to send notification. When i lunch this code, nothing appened (no event match) and no notification on my phone.

Plz help me i really need this code.

Answer 1

I have a suggestion.

In android GcmIntentService class onHandleIntent method us log.d to figure out notification is reaching at android end or not. Sometime our code for show notification is not working and we get confused on which side problem is occurring. Previously i have implemented push notification using C# PushSharp and i face same problem. but error was with my GcmIntentService, sendnotification code at android side.

working GCMIntentService class:
