I have the identical code in a similar situation, and the dialog showed up when i put in a timer before dismissing it. On mine, I've basically assumed that the data retrieval and processing is happening before the dialog really has a chance and am hoping that it will show up on phones that are using a slower 3G connection rather than a direct connection to the net.
See it yours works if you throw in a timer to make it wait a few seconds before calling dismiss(). I'm betting that it will. I'll leave it to others to say whether it will work properly without the timer when actually deployed, as I haven't reached that point yet.
