Blackberry app loads data from Internet on Simulator, but nothing loads on device

Question

Hi,

We have an application that uses XML to load data on 8900 BB device. Everything is running well on Simulator, all relevant data load. But on device we get a black page and nothing loads. Can anyone help us find the problem? Maybe that's because we don't sign the app?

We managed to load data only after we set APN in device network settings. All native and downloaded apps worked before without any APN settings, why didn't our app load data without APN?

Thank you!

Unfortunately, the "answer" to this is "networking is difficult on the BlackBerry". There are some pretty good resources out there to get you quickly up-to-speed, though. Here is a great post on the developer forums all about making network connections and the various different ways to accomplish your task:

Additionally, an accomplished BlackBerry developer has posted a very nice utility class that you might want to try using to bullet-proof your connections more:
