QSystemNetworkInfo is part of Qt Mobility's System Information API, so do you also have lines like these in your .pro-file? Eg.:

CONFIG += mobility
MOBILITY = systeminfo

[popways]

Thank you for your reply.

but

CONFIG += mobility
MOBILITY = systeminfo

have already be added.

in my application,QSystemNetworkInfo is to get cellid.
any other idea?

It's easy to make it happen!

if QSystemNetworkInfo is added in main() function, then the application crash immediately.

why no people help me to fix it?

Do you have Qt Mobility library installled on the phone?

[popways]

Thank you for your reply.

Qt Mobility library 1.00(2) already installed

Is it the same version you have in SDK?

[popways]

yes, I install it under the steps: Start-Program-Nokia Qt SDK-Symbian-Install QtMobility to Symbian Device

I have been blocked by this problem serveral days. uiujhkjhi8ghu8.......................

[divanov]

And Qt is also installed on the phone?

[popways]

I try it on N8.

Same program works well on N8,but crash on 5230.
Qt and QtMobility are installed on 5230 correcttly.

Any other idea appriciated.
I think maybe some bugs in the SDK. I wish experts to fix it.

There is a known crash in QtSystemNetworkInfo on Symbian, that should have been fixed.
