<div dir="ltr">Hi,
<div>i'm developing a messaging app (server and client) for a
subject at university. The proyect involves developing a
server with a REST protocol and an android application. In
order to have a real case to use it to compare developing an
app for android and salifish, i thought that it would be a
good idea to also implement the client for salifish.</div>
<div><br>
</div>
<div>The protocol is quite simple, i already managed to develop
the server, tested via terminal and send messages using a
simple qml app (basically i'm doing ajax calls). My problem is
how should i poll notifications and messages. I have to
periodically send an ajax call/http request to an url (eg:
<a>http://</a><server addr>/notifications) and the server will
answer me with a json with all the new messages. </div>
<div><br>
</div>
<div>My first idea is that the qml app pulls the data directly,
but, if the app is closed, no more data is pulled. Can the qml
app start a service (which runs on the backgound) in order to
continue the pulling of data?.</div>
<div><br>
</div>
<div>My second idea is to run a daemon which periodically pulls
displays notification and communicates with the qml app via
dbus. But, i've read that daemons aren't allowed in harbour
apps, i want to use this prototype as a real test case of what
will be shipping an app to Harbour. </div>
<div><br>
</div>
<div>Which would be the correct / recommended way to pull
information from a server periodically (in the background)?.</div>
<div><br>
</div>
