Hi, 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.
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: http://<server addr>/notifications) and the server will answer me with a json with all the new messages. 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?. 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. Which would be the correct / recommended way to pull information from a server periodically (in the background)?. Regards, Nicolas. -- Nicolas Cisco www.nckweb.com.ar
