My application got refused because they say the application icon appears as a question mark. But I reviewed all the submission process steps and in no place there is mentioned a way to setup the icon, only the store icon.
Here is the message: "Please fix the following issue and resubmit your application as a new release.
After installing your application on the BlackBerry Dev Alpha, we notice the application icon appears as a question mark. If you are using our Eclipse plug-in, please check your BlackBerry_App_Descriptor.xml file and ensure you are specifying your custom application icon correctly. If you still require assistance, please post in our App World Development support forums here: supportforums.blackberry.com/t5/BlackBerry-App-World-Development/bd-p/appworld_dev. "
How can I set it while exporting the game with Construct?
EDIT: I think I solved it. I added to config.xml:
<icon src="icon-150.png" /> (and of course the file icon-150.png)
And submitted the new app. Let's hope for an approval.
