How To Refresh The Screen Automatically In Mobile Application

Hi Venkata RajamVenkata Rajam,

As Kilian Hekhuis said yo can refer the demo on https://www.outsystems.com/forums/discussion/21226/tip-how-to-programmably-auto-refresh-a-mobile-screen/ . But by following this way the screen will get refreshed after every x seconds even if you dont have updated any chats. the best way to do that use firebase notification (https://www.outsystems.com/forge/component/1406/firebase/) component so that you can notify screen when the chats updates and on notify using firebase receiver you can refresh the chats. to do that follow the link to configure firebase https://www.outsystems.com/forums/discussion/25871/how-to-configure-the-firebase-plugin/

Hi Venkata,

What do you want to refresh? Do you display data, and you want to refresh the query? Or do you want to call a REST service every X seconds? Or what?

Anyway, the way to do it is via JavaScript: call setInterval with a function body calling a Screen Action. Don't forget to clearInterval() in the OnDestroy.

Hi Venkata,

I explained above: use a setInterval() in the OnReady, and a clearInterval() in the OnDestroy. Like in this topic (even though the poster didn't quite get it right yet).

Hi Venkata,

You should redirect to the screen, because that will indeed cause the "too many redirects". Instead, you should just refresh the query getting the chats, or the REST service retrieving the chats, and update the list that feeds the chat component. In Mobile Apps, if you refresh/change data bound to a Widget, the Widget refreshes automatically (for Blocks you need the handle OnParametersChanged).

Hi,

Use web sockets instead of refreshing every second. For a chat application are web sockets the best way to post and get data. In the Forge you can find components to implement web sockets in your app.

Hi Furkan Çetin ,

I am also suggesting the same thing by using firebase (Inside firebase the communication will be on web sockets).

How is this different in a Reactive application ???

All I want to do is do a localtion.reload() every 5 seconds ...

I have a javascript with just this line: (I tried in the onInitialize, and the onReady)

$parameters.timeout=setTimeout(location.reload(),5000);

and an onDestroy with clearInterval($parameters.timeout);

...

But the effect I see is a constant refresh iteration caused by the onReady or the onInitialize ...

What is the best way to set this so that I prevent the immediate reload but only do it every 5 seconds?

Where/How should this code be placed?

THANK YOU!

Hi Claudio,

Since this topic is already quite old (almost two years), and since your question is about Reactive Web, not Mobile, please create a new topic with your questions, thanks.
