"rim:background" not working for BB10...?

[ Edited ]



I am trying to implement background activity into my app. I added this code to my config.xml:


    <content src="index.html">
        <rim:background src="bg_execution.html" runOnStartup="true" />        

 to test background activity, I added this code to bg_execution.html:


onload="localStorage.setItem('i', 20);"

Theres a button in my app which reads and alerts this item from the localstorage, but it always shows up NULL --> background task is not working!


On http://developer.blackberry.com/bbos/html5/documentation/rim_background_element_1265316_11.html they say: "If you port your app to BlackBerry 10, you will need to use the <param> lement instead.". But I can't find any further information to this in the api reference.


What did I wrong? Is there another way to do this fpr BB10?


Thanks a lot!

Re: "rim:background" not working for BB10...?

The rim:background element is not supported on BB10, only BBOS.

On BlackBerry 10, we've recently introduced the concept of headless applications to the native SDK:

While our development teams are working to bring this to WebWorks as well, it is not available just yet. Currently the priority for WebWorks is the transition to our Cordova-based implementation.
