How to create an app to consume real time notifications

I want to create an app to consume real time data from an API. This API give me information about different temperatures. When a certain temperature is exceeded my app need to notify the event to the user.

This app need to run in Android and a web browser. So, my problem is the architecture... My app need to be a websocket or a REST API?

Any help is appreciated!!

Solution

  • You need a notification service, and google has something like that for us...

    enter image description here

    how does this works??

    Take a look at the image below,

    you need to register your android app in the google service, and your web interface will need an id, so everytime you want to push something to the android, your web interface instead will push it to the google server with the Id of the app, then google (no matter how) will localize your app, and even if its not running, they will get the notification,

    behind the scenes there is a couple of thing that you must do, bu nothing like launching rockets from the NASA.

    I will suggest to take a look to some tutorials in order to start with the registration of your app, get the api key etc etc..
