how to get device Id for FCM registration in xamarin

Question

i am trying to connect xamarin app with Azure notification hub. for registration i am using this code in onTokenRefresh method.

     var client = new MobileServiceClient(App.MobileServiceUrl);
                var push = client.GetPush();
                var reg = new Registration("??????????", new List<string> { "someTag" });
                await push.RegisterAsync(reg);

Registration object needs "deviceId" as first parameter. where to get this id from, in xamarin's Android project ?

Answer 1

You can obtain that id via the static Firebase instance token property

FirebaseInstanceId.Instance.Token

So this should work:

var reg = new Registration(FirebaseInstanceId.Instance.Token, new List<string> { "someTag" });
