Initialization Error

Hello, I have a QCAR app installed and working properly on my Samsung Galaxy Tab.However, I've created another app and for this app I'm getting this error: "Network connection required to initialize camera settings.Please check your connection and restart the application.If you are still experiencing problems, then your device may not be currently supported." The other app, which had already downloaded the initialization params, still works. But the new one, which hasn't downloaded the params yet, it's not working. I've already checked my internet connection (I can browse on the Web without any problems), so I can't understand why I'm getting this error. I would appreciate any help. Thanks!
