backend-services-push-hybrid-advanced and user registration

[Franck]

Hi,
I was just testing notification push registar samples successfully. I was putting some user data (id, mail, displayname) as custom parameters, but I've seen that some fields looks to be defined to store them. It looks obvious while the push notification browser (on the online platform tool) allows to define segments using fields called User.Email, User.DisplayName etc...
So I gave a try to the backend-services-push-hybrid-advanced sample application on github which makes use of the field User.Id to send notification to a specific user.
I noticed nothing particular in this sample during the registration to push notification, and I noticed that no data related to the user are stored at the device level in the platform.
So my question is simple. Is this feature exists or is broken?
I can live with my custom parameters, but maybe you thought about some features and if there are ways to not reinvent the wheel here, it would be nice to know.
My tests was only realized on android platform, if that can change someting.
Best regards,
Franck

Hi Franck,

Thank you for posting to the Telerik Developer Forums.

The "Advanced" push sample is showcasing the ability to associate a device with user Id and filter notifications on parameters in the user registration.

When a device is registered with a user already logged in (e.g. the request is authenticated with the access token of the user), a UserId field is automatically added by the server to the device registration object and can be observed in the Devices browser. That is why the sample requires user registration/authentication.

The server will automatically resole the notification filter based on the UserId stored in the device registration. You can tailor the segment for push notifications based on user properties defined in the Users content type structure (User.ID, User.DisplayName, etc.).

I hope that this answers your question. Let me know if you have further inquiries.

Hi Admin,

After deploy and run the sample apps, my screen freeze at Initialising push notification for Android....

Could you advice what's the problem?

Thanks

Hello Hong,

May I suggest that you take a look into the latest code base here? Just identified and fixed two minor issues.

However, I mostly assume that the device fails to obtain a device token - is there an internet connection available? More troubleshooting tips are available here.

In addition, could you try deploying to a device using the application package (as APK) or the Build and Deploy option?

If the issue could not be fixed, can your provide the code project (no need to include the keys in it)?

Hi,

May I check is it because I'm using the trial?

In order to send a notification to a subset of users you will need a Telerik Platform subscription plan that supports "Push to Segment".

 

Thanks!

Hello Hong,

During your Telerik Platform Trial you are entitled with a Business tier subscription and you should be able to use the Push to Segments functionality. The app could also run without the functionality to be included in your subscription - you can just tap the Send button and send message to all users (instead of pushing only to a given user or subset of users that will trigger the Push to Segment functionality).

Did you have the chance to check the recommendations from my previous post?
