App crashing

tomjanssens

I have no problem with my N8, but the applications I have deployed so far are very simple.

It's probably best that you debug the application on the device.

Cheers
Tom

Yes, I have upgraded it with the latest Qt from QT SDK 1.1 TP.

I also know that there could be some differences between platforms, but I would not expect so frequent crashing of the application on N8, which works perfectly ok on N97.

What ever you do, do not hard reset your phone.
This will end up in trip to service point for flashing a new firmware.
For the moment you are stuck with the tech preview.

hi borut123,

did you find the problem, i got the same problem when i change the network type (3G wifi..)

sounds like a BC problem to me, did you compile your code with NokiaQtSDK with Symbian^3 SDK ? The sis package for N97 probably won't work on N8 as the BC break between Symbian^3 and Symbian^1

Hi

I've made a few changes in the code, also fixed some memory leaks, installed Qt 4.7.2 and Qt Mobility 1.1.0. Now the app is much more stable than before.

Could you explain a bit more about what you're trying to achieve and maybe send the code snippet
of the "critical part" of youre code.

@borut123, how did you fix some memory leaks? you used some tools? Thanks

borut123

Qt Creator 2.2 has a plugin which uses Valgrind to detect memory leaks.
I think it works on linux and mac (I use it on Ubuntu).

Strange.
Please check again that you are using the latest Qt Creator (not the one which comes with Qt SDK 1.1).

Which operating system are you using?

@borut123, ok, i understand where the problem is: i am using Qt SDK 1.1
