Listener external service

[Andres]

Hello everybody,

I need that my cordova android app reacts to an external service, I mean, I want that my app be like listening to a petition. I am going to have a pc form made with java, and when the user on the pc submits the form, (almost) immediately another user on the tablet see the results.

I was thinking on an interval ajax petition with javascript, but I don't think is the best way. Any advise?

Hi Andres,

From the description you have provided you need something similar to real-time communication functionality. At the current stage Telerik Backend Services do not provide integrated support for real-time services.

Still there is a workaround and as far as I can understand your scenario is very similar to a topic discussed in the forum here. The implementation for you case may include:

• subscribe the app to receive push notifications
• the user on the PC submits the form to Telerik Platform Database - the form data is stored in a content type
• using cloud code for data of the respective content type and its afterCreate/afterUpdate event you automatically send push notification to app users (to all or to interested users only using sending targeted push notifications).

Thus when the app is not running you will be able to notify the app user with a visual that there is something new and interesting on the server (which is the advantage of this approach). If the app is running, you will be able to handle this event and refresh your UI.

Let me know if you need further information.
