Unsubscribing from Google Cloud Messaging Client in an Android App

Question

I am developing an Android application in xamarin using GCM (Google Cloud Messaging) and Azure Notification Hub.

The problem is this: I do not know how to unsubscribe from previous tags. Even when I delete the installation again, the application continues to receive notifications for every tag that I wrote earlier.

meybe I need to implement a function:

protected override void OnUnRegistered(Context context, string registrationId)
{
     throw new NotImplementedException();
}

Answer 1

I think you need to unregister in the Azure Notification Hub.

protected override void OnUnRegistered(Context context, string registrationId)
{
    if (hub != null)
        hub.Unregister();
}

where hubis the same NotificationHubthat you used inOnRegistered

Answer 2

unregister() GoogleCloudMessaging, GCM.

protected override void OnUnRegistered(Context context, string registrationId){
     //Run on background
     GoogleCloudMessaging.getInstance(context).unregister();
}

public void unregister()
